	SUMMARY OF OPERATIONS AND BASIS OF PRESENTATION
	Business Description
	Omega Protein Corporation is a nutritional product company that develops, produces and delivers healthy products throughout the world to improve the nutritional integrity of foods, dietary supplements and animal feeds. The Company operates through two industry segments: animal nutrition and human nutrition.
	The animal nutrition segment is comprised primarily of two subsidiaries: Omega Protein, Inc. (“Omega Protein”) and Omega Shipyard, Inc. (“Omega Shipyard”). Omega Protein, the Company’s principal operating subsidiary, is the successor to a business conducted since 1913. Omega Protein produces and markets a variety of products produced from menhaden (a herring-like species of fish found in commercial quantities in the U.S. coastal waters of the Atlantic Ocean and Gulf of Mexico), including regular grade and value-added specialty fish meals, crude and refined fish oils and fish solubles. Omega Protein’s fish meal products are primarily used as a protein ingredient in animal feed for swine, aquaculture and household pets. Fish oil is utilized primarily for animal and aquaculture feeds, as well as additives to human food products and dietary supplements. Omega Protein’s fish solubles are sold primarily to livestock feed manufacturers, aquaculture feed manufacturers and for use as an organic fertilizer. Omega Protein’s business is seasonal in nature and generally has higher revenues during the third quarter of each fiscal year. A portion of Omega Protein’s production is transferred to the human nutrition segment where it is further processed and sold. Omega Shipyard owns and operates a drydock facility in Moss Point, Mississippi that is used to provide shoreside maintenance for Omega Protein’s fishing fleet and, subject to outside demand and excess capacity, occasionally for third-party vessels.
	The human nutrition segment, which operates under the names Nutegrity and Bioriginal, has three primary product lines: protein products, specialty oils and essential fatty acids and other nutraceutical ingredients. Nutegrity is comprised primarily of three subsidiaries: Cyvex Nutrition, Inc. (“Cyvex”), InCon Processing, L.L.C. (“InCon”) and Wisconsin Specialty Protein, L.L.C. (“WSP”). Cyvex, acquired by the Company in December 2010, is located in Irvine, California and is an ingredient provider in the nutraceutical industry. InCon, acquired by the Company in September 2011, is located in Batavia, Illinois and is a specialty processor that utilizes molecular distillation technology to concentrate Omega-3 fish oils and, subject to outside demand and excess capacity, a variety of other compound products for third-party tolling customers. WSP, acquired by the Company in February 2013, is a manufacturer and marketer of specialty dairy proteins and other related products headquartered in Madison, Wisconsin and operates a production facility in Reedsburg, Wisconsin. See Note 3 – Acquisition of Wisconsin Specialty Protein, L.L.C. for additional information related to the Company’s acquisition of WSP.
	Bioriginal Food & Science Corp. (“Bioriginal”), acquired by the Company in September 2014 and headquartered in Saskatoon, Canada with additional operations in the Netherlands, is a supplier of plant and marine based specialty oils and essential fatty acids to the food and nutraceutical industries. See Note 2 – Acquisition of Bioriginal Food & Science Corp. for additional information related to the Company’s acquisition of Bioriginal.
	Consolidation
	The consolidated financial statements include the accounts of Omega Protein Corporation and its wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.
	Financial Statement Preparation
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the Company’s financial statements and the accompanying notes and the reported amounts of revenues and expenses during the reporting period. Actual amounts, when available, could differ from those estimates and those differences could have a material effect on the financial statements.
	Revenue Recognition
	The Company derives revenue principally from the sales of a variety of protein and oil products derived from menhaden. In addition and as a result of its acquisitions of Cyvex, InCon, WSP and Bioriginal the Company’s revenues include sales of dietary supplement and food ingredients and products. The Company recognizes revenue for the sale of its products when price is established, collectability is reasonably assured and risk and rewards of ownership of its products and title are transferred to the customer.
	Shipping and Handling
	Amounts billed to customers associated with shipping and handling are included in revenues and the related costs are included in cost of sales. For 2014, 2013 and 2012, $10.3 million, $9.4 million and $14.4 million of shipping and handling costs are included in cost of sales, respectively.
	Cash and Cash Equivalents
	The Company considers cash in banks and short-term investments with original maturities of three months or less as cash and cash equivalents.
	Allowances for Doubtful Accounts
	The Company’s receivables are recorded at net realizable value. The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of the Company’s customers to make required payments. The Company considers the following factors when determining if collection is reasonably assured: customer credit worthiness, past transaction history with the customer, and changes in customer payment terms. If the Company has no previous experience with the customer, the Company typically obtains reports from credit organizations to ensure that the customer has a history of paying its creditors. The Company may also request financial information, including financial statements or other documents (e.g., bank statements), or may obtain a letter of credit from the customer to ensure that the customer has the means of making payment. If the financial condition of the Company’s customers were to deteriorate, adversely affecting their ability to make payments, additional allowances would be required.
	Inventories
	Omega Protein’s fishing season runs from mid-April to the first of November in the Gulf of Mexico and from the beginning of May into December in the Atlantic. Government regulations generally preclude Omega Protein from fishing during the off-seasons.
	Omega Protein’s inventory cost system considers all costs associated with an annual fish catch and its processing, both variable and fixed, including both costs incurred during the off-season and during the fishing season. Omega Protein’s costing system allocates cost to inventory quantities on a per unit basis as calculated by a formula that considers total estimated inventoriable costs for a fishing season (including off-season costs) to total estimated units of production and the relative fair market value of the individual products produced. Omega Protein adjusts the cost of sales, off-season costs and inventory balances at the end of each quarter based on revised estimates of total inventoriable costs and units of production. Omega Protein’s lower-of-cost-or-market-value analyses at year-end and at interim periods compare the total estimated per unit production cost of Omega Protein’s expected production to the projected per unit market prices of the products. The impairment analyses involve estimates of, among other things, future fish catches and related costs, and expected commodity prices for the fish products as well as projected purchase commitments from customers. These estimates, which management believes are reasonable and supportable, involve estimates of future activities and events which are inherently imprecise and from which actual results may differ materially.
	During the off-seasons, in connection with the upcoming fishing seasons, Omega Protein incurs costs (e.g., plant and vessel related labor, utilities, rent, repairs, and depreciation) that are directly related to Omega Protein’s infrastructure. These costs accumulate in inventory and are applied as elements of the cost of production of Omega Protein’s products throughout the fishing season ratably based on Omega Protein’s monthly units of production and the expected total units of production for the season.
	Any costs incurred during abnormal downtime related to activity at Omega Protein’s plants are charged to expense as incurred.
	The human nutrition segment generally uses standard costing for inventory it manufactures and FIFO for nutraceutical inventory. The Company’s inventory is stated at the lower of cost or market.
	Business Interruption Insurance Proceeds
	During 2012, the Company received approximately $0.3 million in proceeds, net of deductible, from its business interruption insurance coverage provider related to an incident causing downtime at one of its Gulf of Mexico production facilities in September 2011. The proceeds were calculated based on lost inventory production as well as a small amount of excess costs incurred by the Company as a result of the incident. Given that the Company experienced a slight decrease in production as a result of the incident, the proceeds related to lost inventory production were recognized as an increase in revenues and the proceeds related to excess costs were recognized as a reduction in cost of goods sold.
	Insurance
	Omega Protein carries insurance for certain losses relating to its vessels and Jones Act liabilities for employees aboard its vessels. Omega Protein records gross insurance reserves by using an estimation process that considers Company-specific and industry information as well as management’s experience, assumptions and consultation with counsel. These reserves include estimated settlement costs. In addition, insurance receivables are recorded for those portions of the claims in excess of Company insurance policy annual aggregate deductibles and stop losses. Management’s current estimated range of liabilities related to such cases is based on claims for which management can estimate the amount and range of loss. For those claims where there may be a range of loss, Omega Protein has recorded an estimated liability inside that range, based on management’s experience, assumptions and consultation with counsel. The process of estimating and establishing reserves for these claims is inherently uncertain and the actual ultimate net cost of a claim may vary materially from the estimated amount reserved. There is some degree of inherent variability in assessing the ultimate amount of losses associated with these claims due to the extended period of time that transpires between when a claim occurs and the full settlement of the claim. This variability is generally greater for Jones Act claims by vessel employees. Omega Protein evaluates loss estimates associated with claims and losses as additional information becomes available and revises its estimates. Although management believes estimated reserves related to these claims are adequately recorded, it is possible that actual results could significantly differ from the recorded reserves, which could materially impact Omega Protein’s business, financial condition or results of operations.
	The Company is primarily self-insured for health insurance. The Company purchases individual stop loss coverage with a large deductible. As a result, the Company is primarily self-insured for claims and associated costs up to the amount of the deductible, with claims in excess of the deductible amount being covered by insurance. Expected claims estimates are based on health care trend rates and historical claims data; actual claims may differ from those estimates. The Company evaluates its claims experience related to this coverage with information obtained from its risk management consultants.
	Assumptions used in preparing these insurance estimates are based on factors such as claims settlement patterns, claim development trends, claim frequency and severity patterns, inflationary trends and data reasonableness. Together these factors will generally affect the analysis and determination of the “best estimate” of the projected ultimate claim losses. The results of these evaluations are used to both analyze and adjust the Company’s insurance loss reserves.
	In addition to the above insurance policies, the Company maintains insurance coverage for property, inventory, workers compensation, general liability, product liability and other items. The nature and extent of the insurance coverage varies by line of policy.
	Advertising Costs
	The costs of advertising are expensed as incurred.
	Research and Development
	Costs incurred in research and development activities, primarily related to the Omega Protein Technology and Innovation Center, are expensed as incurred.
	Energy Swap Agreements
	The Company does not enter into financial instruments for trading or speculative purposes. During 2014, 2013 and 2012, Omega Protein entered into energy swap agreements to manage portions of its cash flow exposure related to the volatility of natural gas, diesel and fuel oil energy prices for its fish meal and fish oil production operations. The swaps effectively fix pricing for the quantities listed below during the consumption periods.

									$	275		$	(96	)
	As of December 31, 2014, Omega Protein has recorded a long-term liability of $0.7 million net of the current portion included in other current liabilities of $2.6 million to recognize the fair value of energy swap derivatives, and has also recorded a deferred tax asset of $1.2 million associated therewith. As of December 31, 2013, Omega Protein has recorded a current asset in prepaid expenses of $0.3 to recognize the fair value of energy swap derivatives, and has also recorded a deferred tax liability of $0.1 million associated therewith. The effective portion of the change in fair value from inception to December 31, 2014 is recorded in “accumulated other comprehensive loss” in the Company’s consolidated financial statements. The following table illustrates the changes recorded, net of tax, in accumulated other comprehensive loss resulting from the energy swap agreements.
			(in thousands)

	Net change associated with current period swap transactions, net of tax,			(2,350	)		278
	Balance at December 31,		$	(2,137	)	$	179
	The $2.1 million and $0.2 million reported in accumulated other comprehensive loss as of December 31, 2014 and 2013 will be reclassified to the unallocated inventory cost pool in the period when the energy consumption takes place. The amount to be reclassified, net of taxes, during the next 12 months is expected to be $1.7 million.
	The aggregate fair value of derivative instruments in gross (liability) asset positions as of December 31, 2014 and 2013 was ($3.3) million and $0.3 million, respectively. These amounts represent the maximum exposure to loss at the reporting date as a result of all of the counterparties failing to perform as contracted.

If, at any time, the swaps are determined to be ineffective due to changes in the Company’s energy usage or underlying hedge agreements or assumptions, the fair value of the portion of the energy swaps determined to be ineffective will be recognized as a gain or loss in cost of sales for the applicable period. For 2013, the Company included an expense of $0.1 million in cost of sales resulting from transactions associated with the ineffectiveness of diesel energy swaps. See Note 18 – Fair Value Disclosures for additional information.

Income Taxes
The Company utilizes the asset and liability method to account for income taxes. This method requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of existing temporary differences between the financial reporting and tax reporting basis of assets and liabilities, and operating loss and tax credits carryforwards for tax purposes. The Company records a valuation allowance to reduce the deferred tax assets to the amount that is more likely than not to be realized. The Company believes that the deferred tax assets recorded as of December 31, 2014, net of the valuation allowance, are realizable through future reversals of existing taxable temporary differences and future taxable income. If the Company were to subsequently determine that it would be able to realize deferred tax assets in the future in excess of the net recorded amount, the adjustment would increase earnings for the period in which such determination was made. The Company will continue to assess the adequacy of the valuation allowance on a quarterly basis. Any changes to the estimated valuation allowance could be material to the consolidated financial condition and results of operations.
Accounting for the Impairment of Long-Lived Assets
The Company evaluates at each balance sheet date the continued appropriateness of the carrying value of its long-lived assets, including its long-term receivables and property, plant and equipment. The Company reviews long-lived assets for impairment when events or changes in circumstances indicate that the carrying amount of any such assets or grouping of assets may not be recoverable. The Company has grouped certain assets together (primarily marine vessels) for impairment testing on a fleet basis. If indicators of impairment are present, management evaluates the undiscounted cash flows estimated to be generated by those assets or grouping of assets compared to the carrying amount of those items. The net carrying value of assets or grouping of assets not recoverable is reduced to fair value. The Company considers continued operating losses, or significant and long-term changes in business conditions, to be its primary indicators of a potential impairment.
Plant Closure
Property, plant and equipment impairments related to the Cameron, Louisiana plant are made in accordance with the impairment of long-lived assets policy. Employee severance related charges have been recognized to the extent that the amount is probable, measurable and no-future service is expected or for those still employed, recognized pro-rata over the remaining service period. Ongoing clean-up and dismantlement costs will be recognized as incurred unless obligated and measureable by a contractual commitment. See Note 4 – Plant Closure for additional information related to the charges incurred.
Property, Equipment and Depreciation
Property and equipment additions are recorded at cost. Depreciation of property and equipment is computed by the straight-line method at rates expected to amortize the cost of property and equipment, net of salvage value, over their estimated useful lives. Estimated useful lives, determined at the date of acquisition, of new assets acquired are based primarily on the review of existing property and equipment as well as other factors. Estimated useful lives are as follows:
		Useful Lives
		(years)
Stainless steel equipment			25
Fishing vessels and fish processing plants			15-20
Machinery, equipment, furniture and fixtures and other			10-Mar
Replacements and major improvements are capitalized and amortized over a period of 5 to 15 years. Upon sale or retirement, the costs and related accumulated depreciation are eliminated from the accounts. Any resulting gains or losses are included in the statement of comprehensive income.
Acquisitions, Goodwill and Other Intangible Assets
Goodwill is measured as the excess of the cost of an acquisition over the sum of the amounts assigned to the fair value of tangible and intangible assets acquired less liabilities assumed. The determination of the fair value of the intangible assets acquired involves certain judgments and estimates. These judgments can include, but are not limited to, the cash flows that an asset is expected to generate in the future and the appropriate weighted average cost of capital.
The Company does not amortize goodwill or indefinite-lived intangible assets but performs tests for impairment annually, or when indications of potential impairment exist, utilizing a fair value approach at the reporting unit level. The Company determines fair value using widely accepted valuation techniques, including the income approach which estimates the fair value of its reporting units based on the future discounted cash flows, and the market approach which estimates the fair value of its reporting units based on comparable market prices. In testing for a potential impairment of goodwill, the Company estimates the fair value of its reporting units to which goodwill relates and compares it to the carrying value (book value) of the assets and liabilities related to those businesses.
All of the Company’s goodwill and other intangible assets are the result of acquisitions in the human nutrition segment. This segment is comprised of three reporting units, 1) InCon and Cyvex, 2) WSP and 3) Bioriginal.
The Company amortizes other intangible assets with determinable lives over their estimated useful lives. The Company records an impairment charge on these assets when it determines that their carrying value may not be recoverable. The carrying value is not recoverable if it exceeds the undiscounted future cash flows resulting from the use of the asset and its eventual disposition. When there is existence of one or more indicators of impairment, the Company measures any impairment of intangible assets based on a projected discounted cash flow method using a discount rate determined by the Company’s management to be commensurate with the risk inherent in its business model. The Company’s estimates of future cash flows attributable to its other intangible assets require significant judgment based on the Company’s historical and anticipated results and are subject to many factors. See Note 10 - Goodwill and Other Intangible Assets for more information about goodwill and other intangible assets.
Pension Plans
The Company records the overfunded or underfunded status of defined benefit pension and postretirement plans as an asset or liability in its statement of financial position and changes in that funded status in the year in which the changes occur through other comprehensive income. The Company also measures the funded status of a plan as of the date of its year-end statement of financial position. The Company’s policy is to fund its pension plan at amounts not less than the minimum requirements of the Employee Retirement Income Security Act of 1974.
In 2002, the Board of Directors authorized a plan to freeze the Company’s pension plan in accordance with ERISA rules and regulations so that new employees, hired after July 31, 2002, are not eligible to participate in the pension plan and further benefits no longer accrue for existing participants. The freezing of the pension plan had the effect of vesting all existing participants in their pension benefits in the plan. See Note 15 – Benefit Plans for additional information related to the Company’s pension plans.
Comprehensive Income (Loss)
Comprehensive income (loss) is defined as change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources, including foreign currency translation adjustments, interest and energy swap transactions, and pension benefits adjustments, including recognition of actuarial losses. The Company presents comprehensive income (loss) in its consolidated statements of comprehensive income and consolidated statements of stockholders’ equity.
Accumulated Comprehensive Loss
The components of accumulated other comprehensive loss included in stockholders’ equity are as follows:
Changes in Accumulated Other Comprehensive Loss by Component
For the Year Ended December 31, 2014 (in thousands)
		Gains and Losses			Defined Benefit			Foreign currency			Total
		On Cash Flow			Pension Items			Translation

	(c)	This accumulated other comprehensive income component is reclassified to the unallocated inventory cost pool in the period when the energy consumption takes place.
	(d)	This accumulated other comprehensive income component is included in the computation of net periodic pension costs as amortization of actuarial loss which are explained in more detail in Note 15.
Concentrations of Credit Risk
Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and trade accounts receivable. The Company’s customer base generally remains consistent from year to year. The Company performs ongoing credit evaluations of its customers and generally does not require material collateral. The Company maintains reserves for potential credit losses and such losses have historically been within management’s expectations.
At December 31, 2014, the Company had cash deposits concentrated primarily in one major bank.
Earnings per Share
Basic earnings per share is calculated by dividing net income allocated to common shares outstanding by the weighted average number of shares of common stock outstanding. Diluted earnings per share assumes the exercise of stock options provided the effect is not anti-dilutive.
The Company grants certain incentive compensation awards, including restricted stock, to employees and non-employee directors that are considered to be participating securities. Due to the presence of participating securities, we have calculated our earnings per share using the two-class method. See Note 12 – Reconciliation of Basic and Diluted per Share Data.
Stock-Based Compensation
The Company has a stock-based compensation plan, which is described in more detail in Note 15.
Shares Issued to Directors
In 2014, 2013 and 2012, approximately 0, 3,200 and 7,600 shares of the Company’s stock were issued to directors in non-cash transactions as payment in lieu of Board retainer and per diem fees. Expenses were recognized on these non-cash transactions of approximately $0, $25,200 and $56,100.
Shareholder Rights Plan
On April 1, 2014, the Company’s Board of Directors terminated the Company’s Shareholder Rights Plan (“SRP”). The SRP was adopted in June 2010, shortly after the BP oil spill in the U.S. Gulf of Mexico, and was originally scheduled to terminate in June 2020.
Foreign Currency Translations
All amounts are expressed in U.S. dollars unless otherwise indicated. The U.S. dollar is the functional currency of Bioriginal’s Canadian-based subsidiaries (“Bioriginal Canada”). Monetary assets and liabilities denominated in foreign currencies are translated into U.S. dollars at exchange rates in effect at the balance sheet date. Non-monetary items are translated at rates of exchange in effect when the assets were acquired or obligations incurred. Revenue and expenses are translated at average rates in effect in the period of the transaction. Foreign exchange gains and losses are included in the condensed consolidated statement of comprehensive income.
The Euro is the functional currency of Bioriginal’s Netherlands-based subsidiaries (“Bioriginal Europe”). The operations of these subsidiaries are considered self-sustaining and their financial statements are translated into U.S. dollars using the current rate method. Under this method, all assets and liabilities are translated to U.S. dollars at exchange rates in effect at the balance sheet date and all revenue and expenses are translated at rates in effect at the time of the transactions. Exchange gains and losses arising from this translation, representing the net unrealized foreign currency translation gain (loss) on the Company's net investment in its self-sustaining subsidiaries, are recorded in the accumulated other comprehensive income (loss) component of shareholders' equity. Adjustments to the accumulated other comprehensive income (loss) account are not recorded in the condensed consolidated statement of comprehensive income until realized through a reduction in the Company's net investment in such operations.
Recently Issued Accounting Standards
In November 2014, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update (“ASU”) 2014-17, Business Combinations: Pushdown Accounting.  This ASU amended the Business Combination Accounting Standards Codification to provide guidance on whether and at what threshold an acquired entity that is a business or nonprofit activity can apply pushdown accounting in its separate financial statements. The Company’s adoption of FASB ASU No. 2013-17 effective November 14, 2014 did not have an impact on the Company’s consolidated results of operations, financial position and related disclosures.
In November 2014, the FASB issued Accounting Standards Update (“ASU”) 2014-16, Derivatives and Hedging: Determining whether the Host Contract in a Hybrid Financial Statement Issued in the Form of a Share is More Akin to Debt or Equity.  This ASU amended the Derivatives and Hedging Accounting Standards Codification to eliminate the use of different methods in practice and thereby reduce existing diversity under GAAP in the accounting for hybrid financial instruments used in the form of a share. The new standard is effective in annual periods beginning on or after December 15, 2015 with early adoption permitted. The Company’s adoption of FASB ASU No. 2014-16 is not expected to have an impact on the Company’s consolidated results of operations, financial position and related disclosures.
In August 2014, the FASB issued Accounting Standards Update (ASU) No. 2014-15, Presentation of Financial Statements- Going Concern (Subtopic 205-40). The amendments require management to assess an entity’s ability to continue as a going concern by incorporating and expanding upon certain principles that are currently in the U.S. auditing standards. Specifically, the amendments (1) provide a definition of the term substantial doubt, (2) require an evaluation every reporting period including interim periods, (3) provide principles for considering the mitigating effect of management’s plans, (4) require certain disclosures when substantial doubt is alleviated as a result of consideration of management’s plans, (5) require an express statement and other disclosures when substantial doubt is not alleviated, and (6) require an assessment for a period of one year after the date that the financial statements are issued (or available to be issued). The guidance is effective for annual periods ending after December 15, 2016 and for annual periods thereafter. Early adoption is permitted.  The Company does not expect this ASU to have a material impact on the Company’s consolidated results of operations, financial position and related disclosures.
In June 2014, the FASB issued Accounting Standards Update (ASU) No. 2014-12, Compensation — Stock Compensation (Topic 718), Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period.  A performance target in a share-based payment that affects vesting and that could be achieved after the requisite service period should be accounted for as a performance condition under Accounting Standards Codification (ASC) 718, Compensation — Stock Compensation. As a result, the target is not reflected in the estimation of the award's grant date fair value. Compensation cost would be recognized over the required service period, if it is probable that the performance condition will be achieved.  The guidance is effective for annual periods beginning after December 15, 2015 and interim periods within those annual periods. Early adoption is permitted.  The Company does not expect this ASU to have a material impact on the Company’s consolidated results of operations, financial position and related disclosures.
In May 2014, the FASB issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers.  This ASU amends the existing accounting standards for revenue recognition and is based on the principle that revenue should be recognized to depict the transfer of goods or services to a customer at an amount that reflects the consideration a company expects to receive in exchange for those goods or services.  The Company is required to adopt this ASU on January 1, 2017.  The Company is currently evaluating the potential impact of these changes on the consolidated results of operations, financial position and related disclosures.
In April 2014, the FASB issued ASU No. 2014-08, Presentation of Financial Statements and Property, Plant and Equipment: Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. This ASU changes the criteria for determining which disposals can be presented as discontinued operations and modifies related disclosure requirements. Under the new guidance, a discontinued operation is defined as a disposal of a component or group of components that is disposed of or is classified as held for sale and represents a strategic shift that has or will have a major effect on an entity's operations and financial results. The new standard is effective in annual periods beginning on or after December 15, 2014 with early adoption permitted. The guidance applies prospectively to new disposals and new classifications of disposal groups as held for sale after the effective date. The Company’s adoption of FASB ASU No. 2014-08 is not expected to have an impact on the Company’s consolidated results of operations, financial position and related disclosures.
In July 2013, the FASB issued ASU No. 2013-11, Income Taxes: Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. This ASU amended the Income Taxes Topic of the Accounting Standards Codification to eliminate a diversity in practice for the presentation of unrecognized tax benefits when net operating loss carryforwards, similar tax losses or tax credit carryforwards exist. The amendment requires that the unrecognized tax benefit be presented as a reduction of the deferred tax assets associated with the carryforwards except in certain circumstances when it would be reflected as a liability. This guidance is effective for annual periods and interim periods within those annual periods beginning after December 15, 2013. The Company’s adoption of FASB ASU No. 2013-11 effective January 1, 2014 did not have an impact on the Company’s consolidated results of operations, financial position and related disclosures.

Note 2 - Acquisition of Bioriginal Food & Science Corp. [Line Items]
Mergers, Acquisitions and Dispositions Disclosures [Text Block]	NOTE 2. ACQUISITION OF BIORIGINAL FOOD & SCIENCE CORP.
	A. Description of the Transaction
	On September 5, 2014, the Company acquired all of the issued and outstanding equity of Bioriginal pursuant to the terms of a Share Purchase Agreement (“Purchase Agreement”). Bioriginal is now a wholly owned subsidiary of the Company.  Bioriginal is a leading supplier of plant and marine based specialty oils and essential fatty acids to the food and nutraceutical industries across North America, Europe and Asia. Bioriginal is included as part of the Company’s human nutrition segment.
	B. Recording of Assets Acquired and Liabilities Assumed
	In connection with its acquisition of Bioriginal, the Company paid an aggregate purchase price of $70.5 million, plus an estimated working capital adjustment of $0.7 million, to the sellers as follows: (i) $46.5 million in cash to the sellers, (ii) assumption of approximately $21.5 million of Bioriginal’s indebtedness, and (iii) issuance of 238,377 shares of restricted common stock of the Company valued at approximately $3.2 million (based on a 30-day average closing price) to certain sellers (the “Management Sellers”). The restrictions on the shares will terminate, with certain exceptions, on the third anniversary of the closing date and are subject to the terms and conditions of the Purchase Agreement; see Note - 1 Significant Accounting Policies Summary of Operations and Basis of Presentation for more information on Restricted Stock. The Purchase Agreement also provides for a performance-based earn-out amount of up to a maximum of $8.8 million Canadian dollars to be paid in September 2017 to the Management Sellers for achieving or exceeding certain adjusted EBITDA targets for Bioriginal during calendar years 2014 through 2016; see Note 16 Commitments and Contingencies for additional information. Subsequent to December 31, 2014, the Company received $0.1 million related to the final closing payment.
	The Company incurred approximately $2.8 million in pretax transaction costs directly related to the acquisition that were expensed and included in selling, general and administrative expenses in the consolidated statement of comprehensive income for the year ended December 31, 2014. The acquisition costs consisted primarily of legal, advisory, valuation, and other consulting fees. The transaction has been accounted for using the acquisition method of accounting which requires, among other things, that all assets acquired and liabilities assumed from acquisitions be recognized at their fair values as of the acquisition date. Any excess of the purchase price over the fair values of the net assets acquired are recorded as goodwill. The following table shows the preliminary allocation of the purchase price:
			(in thousands)
	Cash		$	93
	Accounts receivable			15,072
	Inventories			20,309
	Other current assets, net including prepaid expenses			1,820

	Identifiable intangible assets (a)			16,987
	Liabilities assumed			(38,288	)
	Total identifiable net assets			19,019
	Goodwill			27,462
	Total consideration		$	46,481
		(a)	See Note 10 – Goodwill and Other Intangible Assets for weighted average lives.
	Goodwill is calculated as the excess of the consideration transferred over the net assets recognized and represents the future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. Specifically, the goodwill recorded as part of the acquisition of Bioriginal includes the following:
	● the expected synergies and other benefits that the Company believes may result from combining the operations of Bioriginal with the operations of the Company’s human nutrition segment,
	● any intangible assets that do not qualify for separate recognition, and
	● the value of the going-concern element of Bioriginal’s existing business (the higher rate of return on the assembled collection of net assets versus if the Company had acquired all of the net assets separately).
	See Note 10 - Goodwill and Other Intangible Assets, for more information about goodwill and other intangible assets.

	As of December 31, 2014 and 2013, the insurance receivable of $0.5 million and $3.0 million, respectively, primarily relates to Jones Act claims for employees aboard its vessels. This estimated amount is recorded gross of estimated claims which may be due to claimants and is included in accrued insurance liabilities.
	The Company carries insurance for certain losses relating to its fishing vessels and Jones Act liability for employees aboard its vessels (collectively, “Vessel Claims Insurance”). The typical Vessel Claims Insurance policy contains an annual aggregate deductible (“AAD”) for which Omega Protein remains responsible, while the insurance carrier is responsible for all applicable amounts which exceed the AAD. It is Omega Protein’s policy to accrue current amounts due and record amounts paid out on each claim. Once payments exceed the AAD, Omega Protein records an insurance receivable for a given policy year.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets Disclosure [Text Block]	NOTE 10. GOODWILL AND OTHER INTANGIBLE ASSETS
	The Company completed its annual impairment testing of goodwill and other indefinitely lived intangible assets for 1) InCon and Cyvex, as a single reporting unit, and 2) WSP for 2014.  As of December 31, 2014, the carrying value of InCon and Cyvex’s trade secrets and goodwill exceeded its calculated fair values by $0.6 million and $4.1 million, respectively, due primarily to recent operating results and Company revising its forward looking cash flow forecast associated with this reporting unit. Fair value was determined by utilizing market and income approaches. As a result, a $4.7 million impairment expense was recognized during the year ended December 31, 2014. Key assumptions in the fair value calculation include future fish oil and nutraceutical sales volumes and prices, tolling, the portion of sales attributable to trade secrets, production costs and the discount rate.
	As of December 31, 2014, the calculated fair value of WSP’s trade secrets exceeds its $1.1 million carrying value by 100% or more. The calculated fair value of goodwill exceeds its carrying values by less than 1%. Key assumptions in the fair value calculation include dairy protein product sales volumes and prices, the portion of sales attributable to the brand name, the cost of availability of raw materials and the discount rate.
	It should be noted that the assessments of goodwill and indefinitely lived intangible assets are based on assumptions that require speculation and are highly subjective given the early stage and transitional nature of the businesses. The Company’s annual quantitative tests have assumed increasing cash flows over the next several years, based on anticipated sales growth and improved profitability. Considering the level of sensitivity with respect to the key assumptions, if future cash flow expectations decline sufficiently, the estimated fair values would be reduced and could potentially result in a material impairment in a subsequent period.
	During 2013, the Company decided to discontinue use of the Cyvex and InCon brand names over time and replace them with a single brand, Nutegrity, and concluded that the carrying value of those trade names exceeded the fair value.  Subsequently, annual testing of the indefinite life intangible assets of InCon, Cyvex and WSP was performed, and it was concluded that the carrying value of Cyvex’s other trade names exceeded the fair value.  As a result, a cumulative $0.3 million impairment expense was recognized during the year ended December 31, 2013.
	All of the Company’s goodwill and other intangible assets are the result of acquisitions in the human nutrition segment. The following tables summarize the changes in the carrying amount of goodwill resulting from the Company’s acquisitions of Biorginal, WSP, Cyvex and InCon (in thousands):

	Less current maturities			(14,741	)			(3,112	)
	Long-term debt		$	20,486			$	21,130
	The Title XI loans are secured by certain liens on the Company’s fishing vessels and mortgages on the Company’s Reedville, Virginia and Abbeville, Louisiana plants.
	In June 2011, pursuant to the Title XI program, the United States Department of Commerce Fisheries Finance Program (the “FFP”) approved a financing application made by the Company in the amount of $10.0 million (the “Approval Letter”) which expires on June 20, 2016. To date, the Company has not borrowed any amounts under the Approval Letter and its ability to do so has been adversely affected by an EPA notice that the Company’s Omega Protein subsidiary is ineligible, as a result of its previous convictions under the Clean Water Act, for receipt of government contracts or benefits in certain cases. See “Item 1A. Risk Factors” for further detail on this EPA notice. As of December 31, 2014, the Company had approximately $21.1 million of borrowings outstanding under Title XI and was in compliance with all of the covenants contained therein.
	In March 2012, the Company entered into an Amended and Restated Loan Agreement (the “Loan Agreement”) with Wells Fargo Bank, National Association, as administrative agent (the “Agent”) for the lenders (currently Wells Fargo Bank, National Association and JP Morgan Chase Bank, N.A.) (collectively, the “Lenders”) pursuant to which the Lenders agreed to extend credit to the Company in the form of loans (each a “Loan” and collectively, the “Loans”) on a revolving basis of up to $60.0 million (the “Commitment”). In September 2014, the Company and the Lenders amended the Loan Agreement to (i) permit the acquisition by the Company of Bioriginal, (ii) permit certain existing indebtedness of Bioriginal and the related liens, (iii) add certain collateral under the Loan Agreement relating to Bioriginal, and (iv) increase the commitment of the Lenders under the Loan Agreement by $10 million to a total of $70 million. The Loan Agreement also requires the Company to comply with various affirmative and negative covenants affecting the Company’s businesses and operations, including various financial covenants.
	At the election of the Company, any Loans will bear interest at the lesser of (a) the Base Rate (defined as a fluctuating rate equal to the highest of: (x) the rate of interest most recently announced by Agent as its “prime rate,” (y) a rate determined by Agent to be 1.50% above daily one month LIBOR (except during certain periods of time), and (z) the Federal Funds Rate plus 1.00%) plus the Applicable Margin (as defined in the Loan Agreement), (b) a rate per annum determined by Agent to be equal to LIBOR in effect for the applicable interest period plus the Applicable Margin, or (c) the Maximum Rate (as defined in the Loan Agreement).
	All obligations of the Company under the Loan Agreement are secured by a first and superior lien (subject to Permitted Liens, as defined in the Loan Agreement) against any and all assets of the Company (other than the assets of Bioriginal and certain excluded property, including property pledged to secure federal FFP loans).
	The Loan Agreement requires the Company to comply with various affirmative and negative covenants affecting the Company’s businesses and operations. In addition, the Loan Agreement requires the Company to comply with the following financial covenants:
		●	The Company is required to maintain on a consolidated basis Tangible Net Worth equal to at least the sum of the following: (a) $150,000,000, plus (b) 50% of net income (if positive, with no deduction for losses) earned in each quarterly accounting period commencing after June 30, 2011, plus (c) 100% of the net proceeds from any Equity Interests (as defined in the Loan Agreement) issued after the date of the Loan Agreement, plus (d) 100% of any increase in stockholders’ equity resulting from the conversion of debt securities to Equity Interests after the closing date of the Loan Agreement.
		●	The Company is required to maintain on a consolidated basis an Asset Coverage Ratio (as defined in the Loan Agreement) of at least 2.50 to 1.00.
		●	The Company is required to maintain a positive Adjusted Profitability (as defined in the Loan Agreement), measured on a trailing four quarters basis.
	All Loans and all other obligations outstanding under the Loan Agreement are payable in full on March 21, 2017. As of December 31, 2014 and 2013, the Company had $2.0 million and $0, respectively, outstanding under the Loan Agreement and approximately $3.5 million in letters of credit. As of December 31, 2014, the Company was in compliance with all financial covenants under the Loan Agreement. The Company has no off-balance sheet arrangements other than normal operating leases and standby letters of credit.
	On June 6, 2010, Bioriginal Europe entered into a credit facility with ING Bank N.V. which provides borrowings up to 250,000 Euro.  Under the credit facility, interest is paid at 2.97% plus the EURIBOR rate (currently 2.98%) and is secured by Bioriginal Europe’s equipment.  The credit facility contains cross default provisions and other covenants.   As of December 31, 2014, $0 was outstanding under this credit facility.
	On March 31, 2012, Bioriginal Europe entered into a credit facility with ING Commercial Finance B.V. which provides borrowings up to an amount based on accounts receivable and inventory balances, and matures on March 31, 2015.  Advances are repayable on demand and bear interest payable monthly at 1.75% + EURIBOR (currently 1.76%).  The credit facility is secured by accounts receivable and inventory of Bioriginal Europe to a maximum of 85% of accounts receivable and 60% of inventory.  The credit facility contains cross default provisions and other covenants.  As of December 31, 2014, $2.4 million was outstanding under this credit facility, which is included in current maturities.
	On April 15, 2014, Bioriginal Canada entered into a credit facility with HSBC Bank of Canada (the “Bioriginal Credit Facility”) which provides borrowings up to $20.0 million Canadian dollars and matures on March 15, 2019, subject to HSBC’s right to terminate the facility in its sole discretion. Under the Bioriginal Credit Facility, Bioriginal Canada has an operating line of credit for which interest is paid at HSBC prime rate plus 1.25% (currently 4.5%) and is secured by Bioriginal Canada’s accounts receivable and inventory to a maximum of $17.0 million Canadian dollars and is payable on demand. Additionally, there is a separate maximum of $4.2 million related to letters of credit. At September 30, 2014 Bioriginal has issued $4.2 million in letters of credit in support of product purchases from a foreign supplier. Generally these letters of credit are insured by Export Development Canada and are not considered to be drawn under this credit facility. As of December 31, 2014, $9.7 million was outstanding under these subsections of the credit facility, which is included in current maturities.
	The Bioriginal Credit Facility requires Bioriginal to comply with various affirmative and negative covenants affecting Bioriginal’s businesses and operations. In addition, the Bioriginal Credit Facility requires Bioriginal to comply with the following financial covenants:

	The American Jobs Creation Act of 2004 (the “Act”) provides a deduction for income from qualified domestic production activities, which was phased in from 2005 through 2010. In return, the Act also provides for a two-year phase-out of the existing extra-territorial income exclusion (ETI) for foreign sales that was viewed to be inconsistent with international trade protocols by the European Union.
	Under the guidance in FASB ASC 740-10-55 to the Tax Deduction on Qualified Production Activities Provided by the American Jobs Creation Act of 2004, the deduction is treated as a “special deduction”. As such, the special deduction has no effect on deferred tax assets and liabilities existing at the enactment date. Rather, the impact of this deduction is reported in the period in which the deduction is claimed on the Company’s tax return.
	Temporary differences and tax credit carryforwards that gave rise to significant portions of deferred tax assets and liabilities as of December 31, 2014 and 2013 are as follows:
		2014			2013

	The Company or one of its subsidiaries files income tax returns in the U.S. federal jurisdiction, and various states and foreign jurisdictions. With a few exceptions, the Company is no longer subject to U.S. federal, state and local or non-U.S. income tax examinations by tax authorities for years before 2013. The Company is not currently under examination by the Internal Revenue Service, the various states or foreign jurisdictions.
	A reconciliation of the beginning and ending amount of unrecognized tax benefits, as presented in “Other long-term liabilities” on the balance sheet, is as follows:
		2014			2013			2012
		(in thousands)
	Balance at January 1,	$	1,572		$	1,514		$	1,513
	Additions for tax positions of prior years		6			58			37
	Reductions for tax positions of prior years		(174	)		—			(36	)
	Balance at December 31,	$	1,404		$	1,572		$	1,514
Included in the balances at December 31, 2014, 2013 and 2012 are $1.4 million, $1.6 million and $1.5 million, respectively, of tax positions for which the ultimate deductibility is uncertain. The final settlement of these uncertain positions could positively or negatively impact the effective tax rate in the period settled. Because of the impact of deferred tax accounting, other than interest and penalties, the disallowance of the shorter deductibility period would not materially affect the annual effective tax rate but would accelerate the payment of cash to the taxing authority to an earlier period.
The Company recognizes interest accrued related to unrecognized tax benefits in interest expense and penalties in operating expenses. The Company recorded an accrual for payment of $12,000 in interest and $43,000 in penalties at December 31, 2014. The Company recorded an accrual for payment of $81,000 in interest and $26,000 in penalties at December 31, 2013. The Company recorded an accrual for payment of $53,000 in interest and a reversal of $2,000 in penalties at December 31, 2012.

Compensation and Employee Benefit Plans [Text Block]	NOTE 15. BENEFIT PLANS
	Defined Contribution Plan
	All qualified employees of the Company are covered under the Omega Protein 401(k) Savings and Retirement Plan (the “Plan”) as of December 31, 2014. WSP’s 401(k) plan was incorporated into the Plan as of May 1, 2013. The Company’s matching contributions to the Plan were approximately $1.2 million, $1.2 million, and $1.1 million during 2014, 2013, and 2012, respectively.
	Employees of Bioriginal are covered under a separate defined contribution plan. From the date the Company acquired Bioriginal until December 31, 2014, Bioriginal made matching contributions of $0.1 million to its plan.
	Pension Plan
	Plan benefits are generally based on an employee’s years of service and compensation level. The plan has adopted an excess benefit formula integrated with covered compensation.
	In 2002, the Board of Directors froze the Company’s pension plan in accordance with ERISA rules and regulations so that new employees, after July 31, 2002, are not eligible to participate in the pension plan and further benefits no longer accrue for existing participants. The freezing of the pension plan had the effect of vesting all existing participants in their pension benefits in the plan.
	Amounts listed as pension benefits adjustment under the caption “Comprehensive Income (loss)” on the Consolidated Statements of Stockholders’ Equity of $(1.4) million, $3.6 million and $0.3 million for 2014, 2013 and 2012, respectively, represent the change, net of tax, in the portion of the additional pension liability recorded under “Accumulated Other Comprehensive Loss” on the Consolidated Balance Sheet. During 2015, the Company expects total net periodic benefit cost to be approximately $1.0 million. The amounts in accumulated other comprehensive loss that are expected to be recognized as a component of net periodic benefit cost during the 2015 year are as follows (in thousands):
	Net Actuarial Loss		$	1,200
	Prior Service Cost		$	0
	The Company’s funding policy is to make contributions as required by applicable regulations. The Company uses a December 31 measurement date for its pension plan. The following tables set forth the benefit obligations, fair value of plan assets, and the funded status of the Company’s pension plan, amounts recognized in the Company’s financial statements, and the principal weighted average assumptions used:

	The Company, in consultations with its actuarial firm, employs a building block approach in determining the assumed long-term rate of return for plan assets. The Company reviews historical market data and long-term historical relationships between equities and fixed income in accordance with the widely-accepted capital market principle that assets with higher volatility generally generate greater returns over the long run. The Company also evaluates current market factors such as inflation and interest rates before it determines long-term capital market assumptions. After taking into account diversification of asset classes and the need to periodically re-balance asset classes, the Company establishes the assumed long-term portfolio rate of return by a building block approach. The Company also reviews peer data and historical returns to check its long-term rate of return for reasonability and appropriateness.
	A change in the assumed discount rate creates a deferred actuarial gain or loss. Generally, when the assumed discount rate decreases compared to the prior measurement date, a deferred actuarial loss is created. When the assumed discount rate increases compared to the prior measurement date, a deferred actuarial gain is created. Actuarial gains and losses also are created when actual results differ from assumptions. The net of the deferred gains and losses are amortized to pension expense over the average service life of the remaining plan participants, when it exceeds certain thresholds defined in FASB ASC 715-30-35. This approach to amortization of gains and losses has the effect of reducing the volatility of pension expense attributable to investment returns and liability experience. Over time, it is not expected to reduce or increase the pension expense relative to an approach that immediately recognizes losses and gains.
	As a result of the annual review of assumptions, the Company’s 2015 expected return on plan assets is 7.25%, consistent with 2014, and the discount rate decreased from 4.36% to 3.51%. The discount rate selected by the Company is consistent with general movements in interest rates. Additionally, the Company performed a yield curve analysis which concluded that when the Citigroup Yield Curve is applied to the Plan, it produces a discount rate of 3.51% and the selected discount rate is equal to the yield curve analysis.

Plan assets are well diversified and managed by independent investment advisors, who are in turn overseen and monitored by an investment advisor engaged by the Investment Committee. The Plan’s investment objective is long-term capital appreciation with a prudent level of risk. The Plan’s Investment Committee periodically completes asset performance studies with the goal of maintaining an optimal asset allocation in order to meet future Plan benefit obligations. The investment objectives of the Plan assets have a long-term focus and the Plan is invested in accordance with prudent investment practices that emphasize long-term investment fundamentals which avoid any significant concentrations of risks.
Equity securities do not include any of the Company’s common stock at December 31, 2014 and 2013, respectively.

Stock Incentive Plans
On June 27, 2000, the 1998 Incentive Plan and the Director Plan were amended and restated in their entirety and renamed the 2000 Long-Term Incentive Plan (“2000 Incentive Plan”), and the 2000 Incentive Plan was approved by the Company’s stockholders. Under the 2000 Incentive Plan, the Company is authorized to issue shares of Common Stock pursuant to “Awards” granted in various forms, including incentive stock options (intended to qualify under Section 422 of the Internal Revenue Code of 1986, as amended), non-qualified stock options and other similar stock-based Awards. The substantive changes from the 1998 Incentive Plan and the Directors Plan in the amendment and restatement of the 2000 Incentive Plan were (a) the 2000 Incentive Plan allows annual option grant awards of 10,000 shares to each non-employee Director and (b) the 2000 Incentive Plan allows for the aggregate number of option shares available for issuance under the plan to equal 25% of the number of shares of common stock outstanding at any time with an absolute maximum of no more than 15 million shares available for awards at any time. Reference is made to the Company’s 2000 proxy statement for a complete summary of all the differences among the three plans.
On April 13, 2006, the Board of Directors approved the establishment of the Omega Protein Corporation 2006 Incentive Plan (“2006 Incentive Plan”) which was subsequently approved by the Company’s stockholders and became effective on June 7, 2006.
The Company has granted stock options under the 2006 Incentive Plan in the form of non-qualified stock options. See “Stock-Based Compensation” regarding the method the Company utilizes to record compensation expense for employee stock options. The Company establishes the exercise price based on the fair market value of the Company’s stock (as defined in the relevant plan) at the date of grant. Each quarter, the Company reports the potential dilutive impact of stock options in its diluted earnings per common share using the treasury-stock method. Out-of-the-money stock options (i.e., the average stock price during the period is below the strike price of the stock option) are not included in diluted earnings per common share.
The Company has also issued shares of restricted stock under the 2006 Incentive Plan. Holders of shares of restricted stock are entitled to all rights of a stockholder of the Company, including the right to vote the shares and receive any dividends or other distributions. The shares are considered issued and outstanding on the date granted and are included in the basic earnings per share calculation.
Stock-Based Compensation
Stock Options
Net income for the years ended December 31, 2014, 2013 and 2012 includes $0 million, $0.6 million and $3.1 million ($0 million, $0.4 million and $2.0 million after-tax), respectively, of stock-based compensation costs related to stock options which are primarily included in selling, general and administrative expenses in the consolidated statement of comprehensive income. As of December 31, 2014, there was $0 of unrecognized compensation costs related to non-vested stock options.

The fair value of the Company’s stock options is the estimated present value at grant date using the Black-Scholes option pricing model with the following weighted average assumptions for the years ended December 31, 2012: expected dividend yield of 0%; weighted-average volatility of 65.7%; risk-free interest rate of 0.86%; and an expected term of 5 to 6 years. The expected dividend yield is based on the Company’s annual dividend payout at grant date. Expected volatility is based on the historical volatility of the Company’s stock for a period approximating the expected life. The risk-free interest rate is based on the U.S. treasury yield in effect at the time of grant and has a term equal to the expected life. The expected term of the options represents the period of time the options are expected to be outstanding.
Restricted Stock
The Company has issued shares of restricted stock under the 2006 Incentive Plan. Shares of restricted stock have generally vested on the third anniversary of the grant date or in equal installments over three years except for shares of restricted stock granted to non-employee directors which vest six months after the grant date. Non-vested shares are generally forfeited upon the termination of employment or service as a director. Holders of shares of restricted stock are entitled to all rights of a stockholder of the Company, including the right to vote the shares and receive any dividends or other distributions. The non-vested shares are considered participating securities and the Company has calculated earnings per share using the two-class method. See Note 12 – Reconciliation of Basic and Diluted Per Share Data.
Net income for the years ended December 31, 2014, 2013 and 2012 includes $2.0 million, $1.4 million and $0.6 million ($1.3 million, $0.9 million and $0.4 million after-tax), respectively, of stock-based compensation costs related to restricted stock which are primarily included in selling, general and administrative expenses in the consolidated statement of comprehensive income. As of December 31, 2014, there was approximately $4.3 million ($2.8 million after tax) of unrecognized compensation cost related to non-vested restricted shares that is expected to be recognized over a weighted-average period of 1.65 years. Based on restricted stock issued as of December 31, 2014, share-based compensation expense for fiscal year 2015 is expected to be approximately $2.0 million ($1.3 million after tax).
The following table shows restricted stock granted under the 2006 Long-Term Incentive Plan to the Company’s employees and non-employee directors for the year ended December 31, 2014:

The aggregate intrinsic value of the Company’s outstanding non-vested restricted stock at December 31, 2014 and 2013 was $6.1 million and $6.0 million, respectively. 255,850 shares of the Company’s restricted shares outstanding at December 31, 2014 are expected to vest during the year 2015.
Performance Units
On February 6, 2014, the Company adopted a cash incentive performance unit plan. The value of the units will be determined by reference to the performance of the Company’s common stock during the relevant performance period compared to the performance of the Russell 2000 Index member companies (the “Peer Group”) during that same period. One third of the Performance Units granted will be earned at the end of each calendar year of the performance period and will be valued for the calendar year based on the Total Shareholder Return (“TSR”) of the Company compared to the TSR of the Peer Group. The performance units contain a service provision of approximately 3 years and are liability-classified awards included in other long-term liabilities which are adjusted to fair value on a quarterly basis.
The Company’s compensation expense related to performance units was approximately $0.3 million for the year ended December 31, 2014, which is primarily reflected in selling, general and administrative expenses in the consolidated statement of comprehensive income. As of December 31, 2014, there was approximately $0.8 million of unrecognized compensation cost related to performance units that is expected to be recognized over the next 2.0 years, of which $0.4 million of compensation expense is expected to be recognized during the year 2015.

Rental expense for long-term operating leases was $3.1 million, $2.7 million and $2.4 million in 2014, 2013 and 2012, respectively.

Bioriginal Contingency

In September 2014, the Company acquired all of the outstanding equity of Bioriginal pursuant to the terms of a share purchase agreement. A portion of the equity of Bioriginal was indirectly held by the Management Sellers, who continue to be employed by Bioriginal and share in the management of Bioriginal’s business. Bioriginal is now a wholly owned subsidiary of the Company.

In addition to the acquisition date cash purchase price and restricted stock, the Management Sellers may also earn additional amounts based on the annual adjusted EBITDA of Bioriginal’s business during each of the calendar years 2014 through 2016. If the adjusted EBITDA meets or exceeds agreed upon targets for the calendar year, the payout ranging from $1.2 million Canadian dollars to $2.9 million Canadian dollars will be earned, subject to certain forfeitures based on termination of Management Sellers’ employment. The maximum total payment for all three years is $8.8 million Canadian dollars.

The earn-out payments in Canadian dollars, if any, will be estimated on a quarterly basis and paid in September 2017. The Company will record the estimated contractual obligation as compensation expense during each year as it is deemed probable that such amount will be payable. For the year ended December 31, 2014, the Company recorded a $0.4 million liability related to this provision of the agreement. The Company expects that the threshold for a $1.2 million Canadian payment was achieved for 2014.

InCon Contingency

In September 2011, the Company acquired all of the outstanding equity of InCon in a cash transaction pursuant to the terms of an equity purchase agreement. The equity of InCon was indirectly held by four individuals (the “Sellers”), some of whom continue to be employed by InCon and share in the management of InCon’s business. InCon is now a wholly owned subsidiary of the Company.

In addition to the acquisition date cash purchase price, the Sellers may also earn additional amounts based on the annual EBITDA of InCon’s toll processing and specialty product business during calendar years 2012 through 2016. The Company and the Sellers amended the earn-out terms on April 25, 2013 by lowering the earn-out by 35% of the original formula in 2013 and all future years. The annual earn-out provisions (as amended) are determined based on a percentage of InCon’s EBITDA, adjusted for certain product sales and costs, which percentage ranges from 3.25% of the first $3.0 million of EBITDA to 19.5% of EBITDA in excess of $12.0 million.

The annual earn-out payments, if any, will be estimated on a quarterly basis and paid subsequent to year end. The Company will record the estimated contractual obligation as compensation expense during each year as it is deemed probable that such amount will be payable. In addition, the earn-out payments are subject to certain reductions associated with future InCon capital expenditures and forfeitures based on termination of employment of a Seller. For the years ended December 31, 2014, 2013 and 2012, the Company has not recorded an annual earn-out estimate.

Legal Contingencies

The Company was named in a lawsuit filed in federal court in the Southern District of Mississippi in connection with the death of an employee at the Company’s Moss Point, Mississippi plant in April 2012. The lawsuit was dismissed with prejudice by the court in September 2014, and the Company later settled the lawsuit and any possible appeal of the court’s ruling on confidential terms that were not material to the Company’s business, financial condition or results of operations.

Insurance

The Company believes its insurance coverage to be in such form, against such risks, for such amounts and subject to such deductibles and self-retentions as are generally prudent for its operations but the securing of such coverage by necessity requires judgment in the balancing of retained risk and the cost effectiveness of such insurance programs. In recent years, for example, the Company has elected to increase its deductibles and self-retentions in order to manage rising insurance premium costs. These higher deductibles and self-retentions will expose the Company to greater risk of loss if future claims occur.

Insurance coverage may not be available in the future at current costs or on what the Company considers to be commercially reasonable terms. Furthermore, any insurance proceeds received for any loss of, or damage to, any of the Company’s facilities may not be sufficient to restore the loss or damage without negative impact on our results of our business, financial condition or results of operations. In addition, should a Company insurer become insolvent, the Company would be responsible for payment of all outstanding claims associated with that insurer’s policies.

Regulatory Matters

The Company is subject to various possible claims and lawsuits regarding environmental matters. Except as noted below, management believes that costs, if any, related to these matters will not have a material adverse effect on the results of operations, cash flows or financial position of the Company.

In April 2010, the Company received a request for information from the EPA concerning its bail wastewater practices used in its fishing operations at its Reedville, Virgina facility. In February 2011, the U.S. Coast Guard conducted inspections at the Company’s Reedville facility regarding the Reedville vessels’ bilge water discharge practices. Based on these inquiries, both agencies commenced investigations of the Company’s bail waste water and bilge water practices at its Reedville facility. The U.S. Attorney’s Office for the Eastern District of Virginia subsequently reviewed both the results of the Coast Guard inspection and the EPA request for information.

In June 2013, the Company’s subsidiary, Omega Protein, resolved both the U.S. Coast Guard and EPA investigations by entering into a plea agreement with the United States Attorney’s Office for the Eastern District of Virginia. Pursuant to terms of the plea agreement, the Company’s subsidiary pled guilty to two Clean Water Act violations. The plea agreement required the subsidiary to pay a $5.5 million fine, be placed on a three year term of probation, and implement an environmental compliance program. In addition to the $5.5 million fine, the subsidiary was required to make a $2.0 million contribution to the National Fish and Wildlife Foundation to fund projects in Virginia related to the protection of the environmental health of the Chesapeake Bay. The plea agreement was approved by the U.S. District Court for the Eastern District of Virginia in June 2013 and the subsidiary paid both the $5.5 million fine and the $2.0 million contribution in July 2013. Omega Protein will be on probation until June 2016, unless the probation period is terminated earlier by the court. The Company recorded charges related to the investigation of $8.0 million for the year ended 2012.

In 2013, Omega Protein requested an equivalency determination from the U.S. Coast Guard for its Gulf of Mexico fleet regarding the use of certain vessel equipment required for “ocean-going vessels” (as defined by Coast Guard regulations) that operate beyond the 12 nautical mile limit. In April 2013 the Coast Guard granted Omega Protein a partial waiver for its 2013 fishing season that allowed Omega Protein to travel, but not fish, outside 12 nautical miles of shore. In January 2014, the Coast Guard granted Omega Protein’s request to utilize alternate and enhanced management procedures to satisfy the Coast Guard’s required vessel equipment, subject to certain restrictions. The Coast Guard also granted Omega Protein a 12 month waiver from the equipment requirements to allow the Company sufficient time to implement these alternate measures and also allowed fishing beyond the 12 nautical mile limit for a 12 month period, subject to certain restrictions. The Company implemented these alternate measures prior to the 2015 fishing season.

Indemnification

The Company’s Articles of Incorporation and By-Laws limit the liability of the Company’s officers and directors to the fullest extent permitted by Nevada law. Nevada provides that directors of Nevada corporations may be relieved of monetary liabilities for breach of their fiduciary duties as directors, except under certain circumstances, including (i) acts or omissions which involve intentional misconduct, fraud or a knowing violation of law or (ii) the willful or grossly negligent payment of unlawful distributions.

The Company’s Articles of Incorporation and By-Laws generally require the Company to indemnify its directors and officers to the fullest extent permitted by Nevada law. The Company’s Articles of Incorporation and By-Laws also require the Company to advance expenses to its directors and its officers to the fullest extent permitted by Nevada law upon receipt of an undertaking by or on behalf of such director or officer to repay such amount if it should be ultimately determined that they are not entitled to indemnification by the Company. The Company also has entered into indemnification agreements with all of its directors and certain of its officers which provides for the indemnification and advancement of expenses by the Company. The Company also maintains director and officer liability insurance with respect to liabilities arising out of certain matters, including matters arising under the securities laws. This insurance is subject to limitations, conditions and deductibles set forth in the respective insurance policy.

Fair Value Disclosures [Abstract]
Fair Value Disclosures [Text Block]	NOTE 18. FAIR VALUE DISCLOSURES
	The following disclosures of the estimated fair value of financial instruments are made in accordance with the requirements of FASB ASC 825-10-50, Disclosure About Fair Value of Financial Instruments. The estimated fair value amounts have been determined by the Company using available market information and appropriate valuation methodologies and are described in the following paragraphs.
	Fair value estimates are subject to certain inherent limitations. Estimates of fair value are made at a specific point in time, based on relevant market information and information about the financial instrument. The estimated fair values of financial instruments presented below are not necessarily indicative of amounts the Company might realize in actual market transactions. Estimates of fair value are subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates.
	The carrying amounts of cash and cash equivalents, accounts receivables, accounts payable and accrued expenses are the approximate fair value because of the short maturity of these items. For non-financial assets, such as goodwill, carrying values are compared to fair value on an annual basis as required by impairment standards and the carrying value is reduced when determined necessary as a result of impairment testing.
	FASB ASC 820-10 defines fair value, provides a consistent framework for measuring fair value under accounting principles generally accepted in the United States and expands fair value financial statement disclosure requirements. The FASB’s prescribed valuation techniques are based on observable and unobservable inputs. Observable inputs reflect readily obtainable data from independent sources, while unobservable inputs reflect our market assumptions. The standard classifies these inputs into the following hierarchy:
	Level 1 Inputs– Quoted prices for identical instruments in active markets.
	Level 2 Inputs– Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.
	Level 3 Inputs– Instruments with primarily unobservable value drivers.
	The carrying values and respective fair values of the Company’s long-term debt are presented below (in thousands). The fair value of the Company’s total debt is estimated based on the quoted market prices available to the Company for issuance of similar debt with similar terms at year end 2014.
		Years Ended December 31,
		2014		2013
	Total Debt (Level 2):
	Carrying Value	$	35,227	$	24,242
	Estimated Fair Value	$	36,851	$	25,285
	The following tables set forth by level within the fair value hierarchy the Company's financial assets and liabilities that were accounted for at fair value on a recurring basis as of December 31, 2014 and 2013. As required by FASB ASC 820-10, financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company's assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy levels.

	The determination of the fair values above incorporates various factors required under FASB ASC 820-10. These factors include not only the credit standing of the counterparties involved and the impact of credit enhancements (such as cash deposits, letters of credit and priority interests), but also the impact of the Company’s nonperformance risk on its liabilities.
	The fair value of the diesel, propane and natural gas energy swaps is derived from the underlying market price of similar instruments at a specific valuation date. The underlying market price for the diesel and natural gas swaps is based upon the NYMEX Futures Curve. The underlying market price for propane is based upon the Mont Belvieu Propane futures curve. These methods rely upon quoted prices for similar instruments in active markets. When such inputs have a significant impact on the measurement of fair value, the instrument is categorized in Level 2.

		-1	Revenues, gross profit, operating income, and net income (loss) are rounded to thousands each quarter. Therefore, the sum of the quarterly amounts may not equal the annual amounts reported.
		-2	Earnings per share are computed independently for each quarter and the full year based upon respective average shares outstanding. Therefore, the sum of the quarterly earnings per share amounts may not equal the annual amounts reported.
		-3	Gross profit as a percentage of revenues for the quarter ended December 31, 2013 increased substantially as compared to the previous three quarters of 2013. This increase was due to greater than anticipated inventory production after September 30, 2013. As a result, standard cost for 2013 inventory, for which sales commenced largely in the third quarter of 2013, was decreased and cumulatively adjusted all previous sales of 2013 inventory production during the quarter ended December 31, 2013. The impact of the change in standard cost to the quarter ended December 31, 2013 is estimated to be approximately $4 million.
		-4	Included in the quarter ended December 31, 2013 expense is a $6.6 million charge related to the loss on the plant closure. For quarters ended March 31, June 30, September 30 and December 31, 2014 has $1.3 million, $2.6 million, $1.5 million and $1.6 million of expenses related to the loss on the plant closure.
		-5	Included in the quarter ended December 31, 2014 expense is a $4.7 million charge related to impairment of goodwill and other intangible assets.
	The Company’s menhaden harvesting and processing business is seasonal in nature. Omega Protein generally has higher sales during the menhaden harvesting season (which includes the second and third quarter of each fiscal year) due to increased product availability and customer demand. Additionally, due to differences in gross profit margins for Omega Protein’s various products, any variation in the mix of product sales between quarters may result in significant variations of total gross profit margins. As a result, the Company’s quarterly operating results have fluctuated in the past and may fluctuate in the future. In addition, from time to time Omega Protein defers sales of inventory based on prices for its products, which may affect comparable period comparisons.

Accounting Policies [Abstract]
Consolidation, Policy [Policy Text Block]	Consolidation
	The consolidated financial statements include the accounts of Omega Protein Corporation and its wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.
Basis of Accounting, Policy [Policy Text Block]	Financial Statement Preparation
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the Company’s financial statements and the accompanying notes and the reported amounts of revenues and expenses during the reporting period. Actual amounts, when available, could differ from those estimates and those differences could have a material effect on the financial statements.
Revenue Recognition, Policy [Policy Text Block]	Revenue Recognition
	The Company derives revenue principally from the sales of a variety of protein and oil products derived from menhaden. In addition and as a result of its acquisitions of Cyvex, InCon, WSP and Bioriginal the Company’s revenues include sales of dietary supplement and food ingredients and products. The Company recognizes revenue for the sale of its products when price is established, collectability is reasonably assured and risk and rewards of ownership of its products and title are transferred to the customer.
Shipping and Handling Cost, Policy [Policy Text Block]	Shipping and Handling
	Amounts billed to customers associated with shipping and handling are included in revenues and the related costs are included in cost of sales. For 2014, 2013 and 2012, $10.3 million, $9.4 million and $14.4 million of shipping and handling costs are included in cost of sales, respectively.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and Cash Equivalents
	The Company considers cash in banks and short-term investments with original maturities of three months or less as cash and cash equivalents.
Receivables, Policy [Policy Text Block]	Allowances for Doubtful Accounts
	The Company’s receivables are recorded at net realizable value. The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of the Company’s customers to make required payments. The Company considers the following factors when determining if collection is reasonably assured: customer credit worthiness, past transaction history with the customer, and changes in customer payment terms. If the Company has no previous experience with the customer, the Company typically obtains reports from credit organizations to ensure that the customer has a history of paying its creditors. The Company may also request financial information, including financial statements or other documents (e.g., bank statements), or may obtain a letter of credit from the customer to ensure that the customer has the means of making payment. If the financial condition of the Company’s customers were to deteriorate, adversely affecting their ability to make payments, additional allowances would be required.
Inventory, Policy [Policy Text Block]	Inventories
	Omega Protein’s fishing season runs from mid-April to the first of November in the Gulf of Mexico and from the beginning of May into December in the Atlantic. Government regulations generally preclude Omega Protein from fishing during the off-seasons.
	Omega Protein’s inventory cost system considers all costs associated with an annual fish catch and its processing, both variable and fixed, including both costs incurred during the off-season and during the fishing season. Omega Protein’s costing system allocates cost to inventory quantities on a per unit basis as calculated by a formula that considers total estimated inventoriable costs for a fishing season (including off-season costs) to total estimated units of production and the relative fair market value of the individual products produced. Omega Protein adjusts the cost of sales, off-season costs and inventory balances at the end of each quarter based on revised estimates of total inventoriable costs and units of production. Omega Protein’s lower-of-cost-or-market-value analyses at year-end and at interim periods compare the total estimated per unit production cost of Omega Protein’s expected production to the projected per unit market prices of the products. The impairment analyses involve estimates of, among other things, future fish catches and related costs, and expected commodity prices for the fish products as well as projected purchase commitments from customers. These estimates, which management believes are reasonable and supportable, involve estimates of future activities and events which are inherently imprecise and from which actual results may differ materially.
	During the off-seasons, in connection with the upcoming fishing seasons, Omega Protein incurs costs (e.g., plant and vessel related labor, utilities, rent, repairs, and depreciation) that are directly related to Omega Protein’s infrastructure. These costs accumulate in inventory and are applied as elements of the cost of production of Omega Protein’s products throughout the fishing season ratably based on Omega Protein’s monthly units of production and the expected total units of production for the season.
	Any costs incurred during abnormal downtime related to activity at Omega Protein’s plants are charged to expense as incurred.
	The human nutrition segment generally uses standard costing for inventory it manufactures and FIFO for nutraceutical inventory. The Company’s inventory is stated at the lower of cost or market.
Insurance Premiums Revenue Recognition, Policy [Policy Text Block]	Business Interruption Insurance Proceeds
	During 2012, the Company received approximately $0.3 million in proceeds, net of deductible, from its business interruption insurance coverage provider related to an incident causing downtime at one of its Gulf of Mexico production facilities in September 2011. The proceeds were calculated based on lost inventory production as well as a small amount of excess costs incurred by the Company as a result of the incident. Given that the Company experienced a slight decrease in production as a result of the incident, the proceeds related to lost inventory production were recognized as an increase in revenues and the proceeds related to excess costs were recognized as a reduction in cost of goods sold.
Liability Reserve Estimate, Policy [Policy Text Block]	Insurance
	Omega Protein carries insurance for certain losses relating to its vessels and Jones Act liabilities for employees aboard its vessels. Omega Protein records gross insurance reserves by using an estimation process that considers Company-specific and industry information as well as management’s experience, assumptions and consultation with counsel. These reserves include estimated settlement costs. In addition, insurance receivables are recorded for those portions of the claims in excess of Company insurance policy annual aggregate deductibles and stop losses. Management’s current estimated range of liabilities related to such cases is based on claims for which management can estimate the amount and range of loss. For those claims where there may be a range of loss, Omega Protein has recorded an estimated liability inside that range, based on management’s experience, assumptions and consultation with counsel. The process of estimating and establishing reserves for these claims is inherently uncertain and the actual ultimate net cost of a claim may vary materially from the estimated amount reserved. There is some degree of inherent variability in assessing the ultimate amount of losses associated with these claims due to the extended period of time that transpires between when a claim occurs and the full settlement of the claim. This variability is generally greater for Jones Act claims by vessel employees. Omega Protein evaluates loss estimates associated with claims and losses as additional information becomes available and revises its estimates. Although management believes estimated reserves related to these claims are adequately recorded, it is possible that actual results could significantly differ from the recorded reserves, which could materially impact Omega Protein’s business, financial condition or results of operations.
	The Company is primarily self-insured for health insurance. The Company purchases individual stop loss coverage with a large deductible. As a result, the Company is primarily self-insured for claims and associated costs up to the amount of the deductible, with claims in excess of the deductible amount being covered by insurance. Expected claims estimates are based on health care trend rates and historical claims data; actual claims may differ from those estimates. The Company evaluates its claims experience related to this coverage with information obtained from its risk management consultants.
	Assumptions used in preparing these insurance estimates are based on factors such as claims settlement patterns, claim development trends, claim frequency and severity patterns, inflationary trends and data reasonableness. Together these factors will generally affect the analysis and determination of the “best estimate” of the projected ultimate claim losses. The results of these evaluations are used to both analyze and adjust the Company’s insurance loss reserves.
	In addition to the above insurance policies, the Company maintains insurance coverage for property, inventory, workers compensation, general liability, product liability and other items. The nature and extent of the insurance coverage varies by line of policy.
Advertising Costs, Policy [Policy Text Block]	Advertising Costs
	The costs of advertising are expensed as incurred.
Research and Development Expense, Policy [Policy Text Block]	Research and Development
	Costs incurred in research and development activities, primarily related to the Omega Protein Technology and Innovation Center, are expensed as incurred.
Derivatives, Policy [Policy Text Block]	Energy Swap Agreements
	The Company does not enter into financial instruments for trading or speculative purposes. During 2014, 2013 and 2012, Omega Protein entered into energy swap agreements to manage portions of its cash flow exposure related to the volatility of natural gas, diesel and fuel oil energy prices for its fish meal and fish oil production operations. The swaps effectively fix pricing for the quantities listed below during the consumption periods.
	Energy Swap		Consumption Period		Quantity	Price Per Unit			Energy Swap Asset/(Liability) as of			Deferred Tax Asset/(Liability) as of
									31-Dec-14			31-Dec-14

	As of December 31, 2014, Omega Protein has recorded a long-term liability of $0.7 million net of the current portion included in other current liabilities of $2.6 million to recognize the fair value of energy swap derivatives, and has also recorded a deferred tax asset of $1.2 million associated therewith. As of December 31, 2013, Omega Protein has recorded a current asset in prepaid expenses of $0.3 to recognize the fair value of energy swap derivatives, and has also recorded a deferred tax liability of $0.1 million associated therewith. The effective portion of the change in fair value from inception to December 31, 2014 is recorded in “accumulated other comprehensive loss” in the Company’s consolidated financial statements. The following table illustrates the changes recorded, net of tax, in accumulated other comprehensive loss resulting from the energy swap agreements.
			(in thousands)
			2014			2013
	Balance at January 1,		$	179		$	28
	Net loss (gain), net of tax, reclassified to unallocated inventory cost pool			34			(127	)
	Net change associated with current period swap transactions, net of tax,			(2,350	)		278
	Balance at December 31,		$	(2,137	)	$	179
	The $2.1 million and $0.2 million reported in accumulated other comprehensive loss as of December 31, 2014 and 2013 will be reclassified to the unallocated inventory cost pool in the period when the energy consumption takes place. The amount to be reclassified, net of taxes, during the next 12 months is expected to be $1.7 million.
	The aggregate fair value of derivative instruments in gross (liability) asset positions as of December 31, 2014 and 2013 was ($3.3) million and $0.3 million, respectively. These amounts represent the maximum exposure to loss at the reporting date as a result of all of the counterparties failing to perform as contracted.
	As of December 31, 2014 (in thousands)		Gross Amounts of Recognized Assets (Liabilities)			Gross Amounts of Assets (Liabilities)Offset			Net Amounts of Assets (Liabilities) Presented in the Balance Sheet

	Energy swap derivatives – asset position		$	275		$	—		$	275
	If, at any time, the swaps are determined to be ineffective due to changes in the Company’s energy usage or underlying hedge agreements or assumptions, the fair value of the portion of the energy swaps determined to be ineffective will be recognized as a gain or loss in cost of sales for the applicable period. For 2013, the Company included an expense of $0.1 million in cost of sales resulting from transactions associated with the ineffectiveness of diesel energy swaps. See Note 18 – Fair Value Disclosures for additional information.
	Subsequent to December 31, 2014, Omega Protein entered into the following energy swap agreements:
	Energy Swap		Consumption Period		Quantity	Price Per Unit
	Diesel - NYMEX Heating Oil Swap		May – November, 2015		352,025 Gallons	$	1.87
	Natural Gas - NYMEX Natural Gas Swap		April – October, 2015		73,575 MMBTUs	$	3.04

	Propane – NGL-Mont Belvieu Propane		June – November, 2016		308,400 Gallons	$	0.53
Income Tax, Policy [Policy Text Block]	Income Taxes
	The Company utilizes the asset and liability method to account for income taxes. This method requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of existing temporary differences between the financial reporting and tax reporting basis of assets and liabilities, and operating loss and tax credits carryforwards for tax purposes. The Company records a valuation allowance to reduce the deferred tax assets to the amount that is more likely than not to be realized. The Company believes that the deferred tax assets recorded as of December 31, 2014, net of the valuation allowance, are realizable through future reversals of existing taxable temporary differences and future taxable income. If the Company were to subsequently determine that it would be able to realize deferred tax assets in the future in excess of the net recorded amount, the adjustment would increase earnings for the period in which such determination was made. The Company will continue to assess the adequacy of the valuation allowance on a quarterly basis. Any changes to the estimated valuation allowance could be material to the consolidated financial condition and results of operations.
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]	Accounting for the Impairment of Long-Lived Assets
	The Company evaluates at each balance sheet date the continued appropriateness of the carrying value of its long-lived assets, including its long-term receivables and property, plant and equipment. The Company reviews long-lived assets for impairment when events or changes in circumstances indicate that the carrying amount of any such assets or grouping of assets may not be recoverable. The Company has grouped certain assets together (primarily marine vessels) for impairment testing on a fleet basis. If indicators of impairment are present, management evaluates the undiscounted cash flows estimated to be generated by those assets or grouping of assets compared to the carrying amount of those items. The net carrying value of assets or grouping of assets not recoverable is reduced to fair value. The Company considers continued operating losses, or significant and long-term changes in business conditions, to be its primary indicators of a potential impairment.
Costs Associated with Exit or Disposal Activities or Restructurings, Policy [Policy Text Block]	Plant Closure
	Property, plant and equipment impairments related to the Cameron, Louisiana plant are made in accordance with the impairment of long-lived assets policy. Employee severance related charges have been recognized to the extent that the amount is probable, measurable and no-future service is expected or for those still employed, recognized pro-rata over the remaining service period. Ongoing clean-up and dismantlement costs will be recognized as incurred unless obligated and measureable by a contractual commitment. See Note 4 – Plant Closure for additional information related to the charges incurred.
Property, Plant and Equipment, Policy [Policy Text Block]	Property, Equipment and Depreciation
	Property and equipment additions are recorded at cost. Depreciation of property and equipment is computed by the straight-line method at rates expected to amortize the cost of property and equipment, net of salvage value, over their estimated useful lives. Estimated useful lives, determined at the date of acquisition, of new assets acquired are based primarily on the review of existing property and equipment as well as other factors. Estimated useful lives are as follows:
			Useful Lives
			(years)
	Stainless steel equipment			25
	Fishing vessels and fish processing plants			15-20
	Machinery, equipment, furniture and fixtures and other			10-Mar
	Replacements and major improvements are capitalized and amortized over a period of 5 to 15 years. Upon sale or retirement, the costs and related accumulated depreciation are eliminated from the accounts. Any resulting gains or losses are included in the statement of comprehensive income.
Goodwill and Intangible Assets, Policy [Policy Text Block]	Acquisitions, Goodwill and Other Intangible Assets
	Goodwill is measured as the excess of the cost of an acquisition over the sum of the amounts assigned to the fair value of tangible and intangible assets acquired less liabilities assumed. The determination of the fair value of the intangible assets acquired involves certain judgments and estimates. These judgments can include, but are not limited to, the cash flows that an asset is expected to generate in the future and the appropriate weighted average cost of capital.
	The Company does not amortize goodwill or indefinite-lived intangible assets but performs tests for impairment annually, or when indications of potential impairment exist, utilizing a fair value approach at the reporting unit level. The Company determines fair value using widely accepted valuation techniques, including the income approach which estimates the fair value of its reporting units based on the future discounted cash flows, and the market approach which estimates the fair value of its reporting units based on comparable market prices. In testing for a potential impairment of goodwill, the Company estimates the fair value of its reporting units to which goodwill relates and compares it to the carrying value (book value) of the assets and liabilities related to those businesses.
	All of the Company’s goodwill and other intangible assets are the result of acquisitions in the human nutrition segment. This segment is comprised of three reporting units, 1) InCon and Cyvex, 2) WSP and 3) Bioriginal.
	The Company amortizes other intangible assets with determinable lives over their estimated useful lives. The Company records an impairment charge on these assets when it determines that their carrying value may not be recoverable. The carrying value is not recoverable if it exceeds the undiscounted future cash flows resulting from the use of the asset and its eventual disposition. When there is existence of one or more indicators of impairment, the Company measures any impairment of intangible assets based on a projected discounted cash flow method using a discount rate determined by the Company’s management to be commensurate with the risk inherent in its business model. The Company’s estimates of future cash flows attributable to its other intangible assets require significant judgment based on the Company’s historical and anticipated results and are subject to many factors. See Note 10 - Goodwill and Other Intangible Assets for more information about goodwill and other intangible assets.
Pension and Other Postretirement Plans, Policy [Policy Text Block]	Pension Plans
	The Company records the overfunded or underfunded status of defined benefit pension and postretirement plans as an asset or liability in its statement of financial position and changes in that funded status in the year in which the changes occur through other comprehensive income. The Company also measures the funded status of a plan as of the date of its year-end statement of financial position. The Company’s policy is to fund its pension plan at amounts not less than the minimum requirements of the Employee Retirement Income Security Act of 1974.
	In 2002, the Board of Directors authorized a plan to freeze the Company’s pension plan in accordance with ERISA rules and regulations so that new employees, hired after July 31, 2002, are not eligible to participate in the pension plan and further benefits no longer accrue for existing participants. The freezing of the pension plan had the effect of vesting all existing participants in their pension benefits in the plan. See Note 15 – Benefit Plans for additional information related to the Company’s pension plans.
Comprehensive Income, Policy [Policy Text Block]	Comprehensive Income (Loss)
	Comprehensive income (loss) is defined as change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources, including foreign currency translation adjustments, interest and energy swap transactions, and pension benefits adjustments, including recognition of actuarial losses. The Company presents comprehensive income (loss) in its consolidated statements of comprehensive income and consolidated statements of stockholders’ equity.
Stockholders' Equity, Policy [Policy Text Block]	Accumulated Comprehensive Loss
	The components of accumulated other comprehensive loss included in stockholders’ equity are as follows:
	Changes in Accumulated Other Comprehensive Loss by Component
	For the Year Ended December 31, 2014 (in thousands)
			Gains and Losses			Defined Benefit			Foreign currency			Total

		(c)	This accumulated other comprehensive income component is reclassified to the unallocated inventory cost pool in the period when the energy consumption takes place.
		(d)	This accumulated other comprehensive income component is included in the computation of net periodic pension costs as amortization of actuarial loss which are explained in more detail in Note 15.
Concentration Risk, Credit Risk, Policy [Policy Text Block]	Concentrations of Credit Risk
	Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and trade accounts receivable. The Company’s customer base generally remains consistent from year to year. The Company performs ongoing credit evaluations of its customers and generally does not require material collateral. The Company maintains reserves for potential credit losses and such losses have historically been within management’s expectations.
	At December 31, 2014, the Company had cash deposits concentrated primarily in one major bank.
Earnings Per Share, Policy [Policy Text Block]	Earnings per Share
	Basic earnings per share is calculated by dividing net income allocated to common shares outstanding by the weighted average number of shares of common stock outstanding. Diluted earnings per share assumes the exercise of stock options provided the effect is not anti-dilutive.
	The Company grants certain incentive compensation awards, including restricted stock, to employees and non-employee directors that are considered to be participating securities. Due to the presence of participating securities, we have calculated our earnings per share using the two-class method. See Note 12 – Reconciliation of Basic and Diluted per Share Data.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Stock-Based Compensation
	The Company has a stock-based compensation plan, which is described in more detail in Note 15.
	Shares Issued to Directors
	In 2014, 2013 and 2012, approximately 0, 3,200 and 7,600 shares of the Company’s stock were issued to directors in non-cash transactions as payment in lieu of Board retainer and per diem fees. Expenses were recognized on these non-cash transactions of approximately $0, $25,200 and $56,100.
	Shareholder Rights Plan
	On April 1, 2014, the Company’s Board of Directors terminated the Company’s Shareholder Rights Plan (“SRP”). The SRP was adopted in June 2010, shortly after the BP oil spill in the U.S. Gulf of Mexico, and was originally scheduled to terminate in June 2020.
Foreign Currency Transactions and Translations Policy [Policy Text Block]	Foreign Currency Translations
	All amounts are expressed in U.S. dollars unless otherwise indicated. The U.S. dollar is the functional currency of Bioriginal’s Canadian-based subsidiaries (“Bioriginal Canada”). Monetary assets and liabilities denominated in foreign currencies are translated into U.S. dollars at exchange rates in effect at the balance sheet date. Non-monetary items are translated at rates of exchange in effect when the assets were acquired or obligations incurred. Revenue and expenses are translated at average rates in effect in the period of the transaction. Foreign exchange gains and losses are included in the condensed consolidated statement of comprehensive income.
	The Euro is the functional currency of Bioriginal’s Netherlands-based subsidiaries (“Bioriginal Europe”). The operations of these subsidiaries are considered self-sustaining and their financial statements are translated into U.S. dollars using the current rate method. Under this method, all assets and liabilities are translated to U.S. dollars at exchange rates in effect at the balance sheet date and all revenue and expenses are translated at rates in effect at the time of the transactions. Exchange gains and losses arising from this translation, representing the net unrealized foreign currency translation gain (loss) on the Company's net investment in its self-sustaining subsidiaries, are recorded in the accumulated other comprehensive income (loss) component of shareholders' equity. Adjustments to the accumulated other comprehensive income (loss) account are not recorded in the condensed consolidated statement of comprehensive income until realized through a reduction in the Company's net investment in such operations.
New Accounting Pronouncements, Policy [Policy Text Block]	Recently Issued Accounting Standards
	In November 2014, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update (“ASU”) 2014-17, Business Combinations: Pushdown Accounting.  This ASU amended the Business Combination Accounting Standards Codification to provide guidance on whether and at what threshold an acquired entity that is a business or nonprofit activity can apply pushdown accounting in its separate financial statements. The Company’s adoption of FASB ASU No. 2013-17 effective November 14, 2014 did not have an impact on the Company’s consolidated results of operations, financial position and related disclosures.
	In November 2014, the FASB issued Accounting Standards Update (“ASU”) 2014-16, Derivatives and Hedging: Determining whether the Host Contract in a Hybrid Financial Statement Issued in the Form of a Share is More Akin to Debt or Equity.  This ASU amended the Derivatives and Hedging Accounting Standards Codification to eliminate the use of different methods in practice and thereby reduce existing diversity under GAAP in the accounting for hybrid financial instruments used in the form of a share. The new standard is effective in annual periods beginning on or after December 15, 2015 with early adoption permitted. The Company’s adoption of FASB ASU No. 2014-16 is not expected to have an impact on the Company’s consolidated results of operations, financial position and related disclosures.
	In August 2014, the FASB issued Accounting Standards Update (ASU) No. 2014-15, Presentation of Financial Statements- Going Concern (Subtopic 205-40). The amendments require management to assess an entity’s ability to continue as a going concern by incorporating and expanding upon certain principles that are currently in the U.S. auditing standards. Specifically, the amendments (1) provide a definition of the term substantial doubt, (2) require an evaluation every reporting period including interim periods, (3) provide principles for considering the mitigating effect of management’s plans, (4) require certain disclosures when substantial doubt is alleviated as a result of consideration of management’s plans, (5) require an express statement and other disclosures when substantial doubt is not alleviated, and (6) require an assessment for a period of one year after the date that the financial statements are issued (or available to be issued). The guidance is effective for annual periods ending after December 15, 2016 and for annual periods thereafter. Early adoption is permitted.  The Company does not expect this ASU to have a material impact on the Company’s consolidated results of operations, financial position and related disclosures.
	In June 2014, the FASB issued Accounting Standards Update (ASU) No. 2014-12, Compensation — Stock Compensation (Topic 718), Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period.  A performance target in a share-based payment that affects vesting and that could be achieved after the requisite service period should be accounted for as a performance condition under Accounting Standards Codification (ASC) 718, Compensation — Stock Compensation. As a result, the target is not reflected in the estimation of the award's grant date fair value. Compensation cost would be recognized over the required service period, if it is probable that the performance condition will be achieved.  The guidance is effective for annual periods beginning after December 15, 2015 and interim periods within those annual periods. Early adoption is permitted.  The Company does not expect this ASU to have a material impact on the Company’s consolidated results of operations, financial position and related disclosures.
	In May 2014, the FASB issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers.  This ASU amends the existing accounting standards for revenue recognition and is based on the principle that revenue should be recognized to depict the transfer of goods or services to a customer at an amount that reflects the consideration a company expects to receive in exchange for those goods or services.  The Company is required to adopt this ASU on January 1, 2017.  The Company is currently evaluating the potential impact of these changes on the consolidated results of operations, financial position and related disclosures.
	In April 2014, the FASB issued ASU No. 2014-08, Presentation of Financial Statements and Property, Plant and Equipment: Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. This ASU changes the criteria for determining which disposals can be presented as discontinued operations and modifies related disclosure requirements. Under the new guidance, a discontinued operation is defined as a disposal of a component or group of components that is disposed of or is classified as held for sale and represents a strategic shift that has or will have a major effect on an entity's operations and financial results. The new standard is effective in annual periods beginning on or after December 15, 2014 with early adoption permitted. The guidance applies prospectively to new disposals and new classifications of disposal groups as held for sale after the effective date. The Company’s adoption of FASB ASU No. 2014-08 is not expected to have an impact on the Company’s consolidated results of operations, financial position and related disclosures.
	In July 2013, the FASB issued ASU No. 2013-11, Income Taxes: Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. This ASU amended the Income Taxes Topic of the Accounting Standards Codification to eliminate a diversity in practice for the presentation of unrecognized tax benefits when net operating loss carryforwards, similar tax losses or tax credit carryforwards exist. The amendment requires that the unrecognized tax benefit be presented as a reduction of the deferred tax assets associated with the carryforwards except in certain circumstances when it would be reflected as a liability. This guidance is effective for annual periods and interim periods within those annual periods beginning after December 15, 2013. The Company’s adoption of FASB ASU No. 2013-11 effective January 1, 2014 did not have an impact on the Company’s consolidated results of operations, financial position and related disclosures.

[1]	Revenues, gross profit, operating income, and net income (loss) are rounded to thousands each quarter. Therefore, the sum of the quarterly amounts may not equal the annual amounts reported.
[2]	Excludes revenue from internal customers of $1.9 million for fish oil that was transferred from the animal nutrition segment to the human nutrition segment at cost.
[3]	Excludes revenue from internal customers of $1.3 million for fish oil that was transferred from the animal nutrition segment to the human nutrition segment at cost.
[4]	Excludes revenue from internal customers of $1.6 million for fish oil that was transferred from the animal nutrition segment to the human nutrition segment at cost.
[5]	Gross profit as a percentage of revenues for the quarter ended December 31, 2013 increased substantially as compared to the previous three quarters of 2013. This increase was due to greater than anticipated inventory production after September 30, 2013. As a result, standard cost for 2013 inventory, for which sales commenced largely in the third quarter of 2013, was decreased and cumulatively adjusted all previous sales of 2013 inventory production during the quarter ended December 31, 2013. The impact of the change in standard cost to the quarter ended December 31, 2013 is estimated to be approximately $4 million.
[6]	Included in the quarter ended December 31, 2013 expense is a $6.6 million charge related to the loss on the plant closure. For quarters ended March 31, June 30, September 30 and December 31, 2014 has $1.3 million, $2.6 million, $1.5 million and $1.6 million of expenses related to the loss on the plant closure.
[7]	Included in the quarter ended December 31, 2014 expense is a $4.7 million charge related to impairment of goodwill and other intangible assets.
[8]	Includes revenues and related expenses for Bioriginal from September 5, 2014 through December 31, 2014.
[9]	Includes revenues and related expenses for WSP from February 27, 2013 through December 31, 2013.

[1]	Revenues, gross profit, operating income, and net income (loss) are rounded to thousands each quarter. Therefore, the sum of the quarterly amounts may not equal the annual amounts reported.
[2]	Excludes revenue from internal customers of $1.9 million for fish oil that was transferred from the animal nutrition segment to the human nutrition segment at cost.
[3]	Excludes revenue from internal customers of $1.3 million for fish oil that was transferred from the animal nutrition segment to the human nutrition segment at cost.
[4]	Excludes revenue from internal customers of $1.6 million for fish oil that was transferred from the animal nutrition segment to the human nutrition segment at cost.
[5]	Gross profit as a percentage of revenues for the quarter ended December 31, 2013 increased substantially as compared to the previous three quarters of 2013. This increase was due to greater than anticipated inventory production after September 30, 2013. As a result, standard cost for 2013 inventory, for which sales commenced largely in the third quarter of 2013, was decreased and cumulatively adjusted all previous sales of 2013 inventory production during the quarter ended December 31, 2013. The impact of the change in standard cost to the quarter ended December 31, 2013 is estimated to be approximately $4 million.
[6]	Included in the quarter ended December 31, 2013 expense is a $6.6 million charge related to the loss on the plant closure. For quarters ended March 31, June 30, September 30 and December 31, 2014 has $1.3 million, $2.6 million, $1.5 million and $1.6 million of expenses related to the loss on the plant closure.
[7]	Included in the quarter ended December 31, 2014 expense is a $4.7 million charge related to impairment of goodwill and other intangible assets.
[8]	Earnings per share are computed independently for each quarter and the full year based upon respective average shares outstanding. Therefore, the sum of the quarterly earnings per share amounts may not equal the annual amounts reported.
