	NOTE 1. SIGNIFICANT ACCOUNTING POLICIES
	SUMMARY OF OPERATIONS AND BASIS OF PRESENTATION
	Business Description
	Omega Protein Corporation is a nutritional company that develops, produces and delivers healthy products throughout the world to improve the nutritional integrity of functional 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 name Nutegrity, has three primary product lines: protein products, Omega-3 fish oil ingredients 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 participates in the nutraceutical industry as an ingredient provider. InCon, acquired by the Company in September 2011, is located in Batavia, Illinois and is a specialty toll processor that utilizes molecular distillation technology to concentrate a variety of compound products, including Omega-3 fish oils. WSP, acquired by the Company on February 27, 2013, is a manufacturer and marketer of specialty dairy and other protein products headquartered in Madison, Wisconsin and operates a production facility in Reedsburg, Wisconsin. See Note 2 – Acquisition of Wisconsin Specialty Protein, L.L.C. for additional information related to the Company’s acquisition of WSP.
	Basis of Presentation
	These interim financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information, the instructions to Quarterly Report on Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, certain information and footnote disclosures normally provided have been omitted. The interim financial statements should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2012. The year end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America.
	In the opinion of management the accompanying unaudited condensed consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments) necessary for a fair statement of the Company’s consolidated financial position as of September 30, 2013, and the results of its operations for the three and nine month periods ended September 30, 2013 and 2012 and its cash flows for the nine month periods ended September 30, 2013 and 2012. Operating results are not necessarily indicative of the results that may be expected for the year ending December 31, 2013.
	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.
	Certain amounts applicable to the prior periods have been reclassified to conform to the classifications currently followed. Specifically, the presentation of our unaudited condensed consolidated statements of comprehensive income for the three and nine months ended September 30, 2012 was revised to classify $6.2 million and $10 million, respectively, of shipping and handling related costs that were previously netted against revenue to cost of sales.  These revisions were not considered to be material, individually or in the aggregate, to previously issued financial statements. These revisions had no effect on the results of operations (net or comprehensive income), financial condition (stockholders’ equity), or cash flows in any period presented or in any previously issued financial statements.
	Additionally, for the nine months ended September 30, 2012, the Company reclassified $0.7 million of cash flows from investing activities to cash flows from operating activities related to accrued capital expenditures.  This revision was not considered to be material, individually or in the aggregate, to previously issued financial statements. The revisions had no effect on the results of operations (net or comprehensive income) or financial condition (stockholders’ equity).
	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 recent acquisitions of Cyvex, InCon and WSP, the Company’s revenues also include sales of dietary supplement ingredients to the nutraceutical industry and whey protein products to the food and nutritional supplement industries. The Company recognizes revenue for the sale of its products when price is established, collectability is reasonably assured, and title and rewards of ownership of its products 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.
	Inventories
	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.
	Energy Swap Agreements
	The Company does not enter into financial instruments for trading or speculative purposes. Omega Protein enters 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.

														$	134,200			$	(15,100	)
	As of September 30, 2013 and December 31, 2012, Omega Protein has recorded a long-term asset of $1,000 and $0, respectively, net of the current portion included in prepaid expenses and other current assets of $34,000 and $134,200, respectively, to recognize the fair value of energy swap derivatives, and has also recorded a deferred tax liability of $12,200 and $15,100, respectively, associated therewith. The effective portion of the change in fair value from inception to September 30, 2013 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 income (loss) resulting from the energy swap agreements (in thousands).
			Three Months Ended								Nine Months Ended
			September 30,								September 30,
			2013				2012				2013				2012
	Beginning balance		$	(78	)		$	(720	)		$	28			$	(420	)
	Net (gain) loss, net of tax, reclassified to unallocated inventory cost pool			(92	)			116				(108	)			377
	Net change associated with current period swap transactions, net of tax			193				895				103				334
	Ending balance		$	23			$	291			$	23			$	291
	The $22,700 reported in accumulated other comprehensive loss as of September 30, 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 approximately $22,100.
	The aggregate fair value of derivative instruments in gross asset positions as of September 30, 2013 and December 31, 2012 was $58,000 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. This exposure could be reduced by up to $5,000 and $0.2 million, respectively, of liabilities included in master netting arrangements with those same counterparties.
	The aggregate fair value of derivative instruments in gross liability positions as of September 30, 2013 and December 31, 2012 was $24,000 and $0, 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. This exposure could be reduced by up to $6,000 and $0, respectively, of assets included in master netting arrangements with those same counterparties.
	As of September 30, 2013 (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		$	58			$	(5	)		$	53
	Energy swap derivatives – liability position		$	(24	)		$	6			$	(18	)
	As of December 31, 2012 (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		$	295			$	(161	)		$	134
	If, at any time, the swaps are determined to be ineffective, in whole or in part, 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 the nine months ended September 30, 2013 and 2012, the Company recognized a charge of $0.1 and $0, respectively, to cost of sales resulting from transactions associated with the prior ineffectiveness of diesel energy swaps. See Note 16 – Fair Value Disclosures for additional information.
	Acquisitions, Goodwill and Other Intangible Assets
	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, Cyvex, InCon and WSP. On February 27, 2013, the Company purchased all of the equity interests in WSP. In the third quarter of 2011, the Company completed its acquisition of InCon Processing, L.L.C., a Delaware limited liability company. In the fourth quarter of 2010, the Company completed its acquisition of Cyvex Nutrition, Inc., a California corporation. All three acquisitions were accounted for as cash transactions using the acquisition method of accounting. Accordingly, the Company has recorded goodwill and certain other identifiable intangible assets that are more fully explained in Note 2 – Acquisition of Wisconsin Specialty Protein, L.L.C. and Note 8 – Goodwill and Other Intangible Assets.
	Construction Contract
	Omega Shipyard engaged in a single fixed price construction contract with a third party that was completed in the fourth quarter of 2012.  The contract provided for revenue to be billed as milestones were attained based on the total estimated construction cost. The Company recognized revenue and expenses related to the contract on a percentage of completion basis based on a ratio of costs incurred to date bore to total projected costs.
	During the quarter ended June 30, 2012, Omega Shipyard revised its total estimated construction costs such that the Company expected to have gross loss upon completion.  As a result, gross profit recognized on the contract in previous quarters was reversed and the full extent of the expected loss was recognized during the quarter ended June 30, 2012.  The Company reassessed these estimates on a quarterly basis. For the three and nine months ended September 30, 2012, the Company incurred gross losses of $0.1 million and $0.5 million, respectively, with respect to the construction contract. There were no third party construction contracts during 2013.
Accumulated Other Comprehensive Loss
The components of accumulated other comprehensive (loss) gain, net of tax, included in stockholders’ equity are as follows:
Changes in Accumulated Other Comprehensive Loss by Component
For the Nine Months Ended September 30, 2013 (in thousands)
		Gains and Losses					Defined Benefit					Total
		On Cash Flow					Pension Items
		Hedges
Beginning balance December 31, 2012		$	28				$	(9,952	)			$	(9,924	)
Other comprehensive loss before reclassifications			103					—					103
Amounts reclassified from accumulated other comprehensive loss			(108	)	(a)			753		(b)			645
Net current-period other comprehensive income			(5	)				753					748
Ending balance September 30, 2013		$	23				$	(9,199	)			$	(9,176	)
	(a)	This accumulated other comprehensive income component is reclassified to the unallocated inventory cost pool in the period when the energy consumption takes place.
	(b)	This accumulated other comprehensive income component is included in the computation of net periodic pension costs as amortization of actuarial gains which are explained in more detail in Note 16 to the consolidated financial statements of the Company’s Form 10-K for the fiscal year ended December 31, 2012.
Recently Issued Accounting Standards
In July 2013, the FASB issued ASU No. 2013-11 which 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 is currently evaluating the impact the adoption of this guidance will have on its consolidated financial statements.
On February 5, 2013, the FASB issued ASU No. 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. The standard requires companies to present, either in a single note or parenthetically on the face of the financial statements, the effect of significant amounts reclassified from each component of accumulated other comprehensive income based on its source and the income statement line items affected by the reclassification. The standard is effective prospectively for public entities for fiscal years, and interim periods within those years, beginning after December 12, 2012, which corresponds to the Company’s first fiscal quarter beginning January 1, 2013. The Company’s adoption of FASB ASU No. 2013-02, effective January 1, 2013, did not have an impact on the Company’s consolidated results of operations or financial position.
In January 2013, the FASB issued ASU No. 2013-01, Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities. The standard limits the scope of balance sheet offsetting disclosures, contained in the new guidance issue in December 2011 discussed below, to recognized derivative instruments, repurchase agreements and securities borrowing and lending transactions. Effective for annual and interim periods beginning on or after January 1, 2013, the Company’s adoption of FASB ASU No. 2013-01 effective January 1, 2013 did not have an impact on the Company’s consolidated results of operations, financial position and related disclosures.
In July 2012, the FASB issued ASU No. 2012-02 regarding subsequent measurement guidance for long-lived intangibles. This guidance is meant to reduce the cost and complexity of performing an impairment test for indefinite-lived intangible assets by simplifying how an entity tests those assets for impairment and to improve consistency in impairment testing guidance among long-lived asset categories. This guidance is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, which corresponds to the Company’s first fiscal quarter beginning January 1, 2013. The Company’s adoption of FASB ASU No. 2012-02 effective January 1, 2013 did not have an impact on the Company’s consolidated results of operations, financial position and related disclosures.
In December 2011, the FASB issued ASU No. 2011-11, Disclosures about Offsetting Assets and Liabilities. The standard requires an entity to disclose information about offsetting and related arrangements to enable users of its financial statements to understand the effect of those arrangements on its financial position. The amendments in this update will enhance disclosures required by U.S. GAAP by requiring improved information about financial instruments and derivative instruments to help reconcile differences in the offsetting requirements under U.S. GAAP and International Financial Reporting Standards (IFRS). The amendments are effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. The Company’s adoption of FASB ASU No. 2011-11 effective January 1, 2013 did not have an impact on the Company’s consolidated results of operations or financial position.
Stock-Based Compensation
Stock Options
The Company has a stock-based compensation plan, which is described in more detail in Note 16 to the consolidated financial statements of the Company’s Form 10-K for the fiscal year ended December 31, 2012. The Company has issued non-qualified stock options under its stock incentive plans. The options generally vest in equal installments over three years and expire in ten years. Non-vested options are generally forfeited upon termination of employment.
Net income for the three months ended September 30, 2013 and 2012 includes $0.2 million and $0.8 million ($0.1 million and $0.5 million after-tax), respectively, of stock-based compensation costs related to stock options. Net income for the nine months ended September 30, 2013 and 2012 includes $0.5 million and $2.3 million ($0.3 million and $1.5 million after-tax), respectively, of stock-based compensation costs related to stock options. The stock-based compensation costs related to stock options are recorded primarily in selling, general and administrative expenses in the unaudited condensed consolidated statement of comprehensive income. As of September 30, 2013 there was $0.1 million ($0.1 million after-tax) of total unrecognized compensation costs related to non-vested stock options that is expected to be recognized during the remainder of fiscal year 2013.
Restricted Stock
The Company has issued shares of restricted stock under the 2006 Incentive Plan. Shares of restricted stock generally vest on the third anniversary of the grant date 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 13 – Reconciliation of Basic and Diluted Per Share Data.
During the nine month periods ended September 30, 2013 and 2012, the Company issued 58,036 and 25,000 shares of restricted stock for each period, respectively, under the 2006 Incentive Plan to employees and non-employee directors. The Company’s compensation expense related to restricted stock was approximately $0.4 million and $0.1 million ($0.3 million and $0.1 million after tax) for the three months ended September 30, 2013 and 2012, respectively, and $1.0 million and $0.4 million ($0.6 million and $0.3 million after tax) for the nine months ended September 30, 2013 and 2012, respectively, which is primarily reflected in selling, general and administrative expenses in the unaudited condensed consolidated statement of comprehensive income. As of September 30, 2013, there was approximately $1.9 million ($1.2 million after tax) of unrecognized compensation cost related to non-vested restricted stock that is expected to be recognized over a weighted-average period of 1.6 years, of which $0.4 million ($0.3 million after-tax) of total restricted stock compensation is expected to be recognized during the remainder of fiscal year 2013.

Mergers, Acquisitions and Dispositions Disclosures [Text Block]	'
	NOTE 2. ACQUISITION OF WISCONSIN SPECIALTY PROTEIN, L.L.C.
	A. Description of the Transaction
	On February 27, 2013, the Company acquired 100% of the outstanding equity interest of WSP, a Wisconsin limited liability company, in a cash transaction pursuant to the terms of an agreement and plan of merger. WSP is now a wholly owned subsidiary of the Company. WSP produces and markets a variety of value-added whey protein ingredients for the food and nutritional supplement industries, including organic and other specialty protein products, using processes applicable to a variety of nutritional dairy ingredients. The Company believes the acquisition of WSP will enhance its presence in the specialty proteins markets and advance its goal of providing sustainable, value-added nutrition ingredients. WSP is included as part of the Company’s human nutrition segment.
	B. Recording of Assets Acquired and Liabilities Assumed
	The Company paid an aggregate cash purchase price for the equity of WSP of $26.5 million plus $0.6 million representing WSP’s excess working capital on the closing date and reimbursable capital expenditures, utilizing cash on hand.
	The Company incurred approximately $0.8 million in pretax transaction costs directly related to the acquisition that were expensed and included in selling, general and administrative expenses in the unaudited condensed consolidated statement of comprehensive income for the nine month period ended September 30, 2013. 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 summarizes the fair values of the WSP assets and acquired liabilities assumed.
			Amounts recognized as of acquisition date
			(in thousands)
	Cash		$	403
	Other current assets, net including receivables, prepaid and inventory			2,515
	Property, plant, and equipment, net			14,095
	Identifiable intangible assets (a)			4,920
	Liabilities assumed			(5,996	)
	Total identifiable net assets			15,937
	Goodwill			11,142
	Total consideration, prior to final working capital adjustment		$	27,079
		(a)	See Note 8 – 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 WSP includes the following:
	● the expected synergies and other benefits that the Company believes will result from combining the operations of WSP with the operations of the Company’s human nutrition segment, including Cyvex and InCon,
	● any intangible assets that do not qualify for separate recognition, and
	● the value of the going-concern element of WSP’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).
	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. See Note 8 - Goodwill and Other Intangible Assets, for more information about goodwill and other intangible assets.
	WSP’s results of operations are included in the Company’s unaudited condensed consolidated statement of comprehensive income beginning on February 27, 2013. Revenues generated by WSP included in the unaudited condensed consolidated statement of comprehensive income from February 27, 2013 through September 30, 2013 were approximately $6.6 million. Net income for the same period was approximately $35,000.
	C. Unaudited Pro Forma Financial Information
	The unaudited financial information in the table below summarizes the combined results of operations of the Company and WSP on a pro forma basis, as though the companies had been combined as of January 1, 2012. The pro forma financial information is presented for informational purposes only and is not indicative of the results of operations that would have been achieved if the acquisition had actually taken place on January 1, 2012 and is not intended to be a projection of future results or trends.

	As of September 30, 2013 and December 31, 2012, the insurance receivable of $1.8 million and $8.6 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 unit’s 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, net of allowance for doubtful accounts. As of September 30, 2013 and December 31, 2012, there was no allowance for doubtful insurance receivable accounts.

	NOTE 8. 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.
	During the third quarter of 2013, the Company decided to discontinue use of the Cyvex and InCon brand names over time and replace them with a single brand, Nutegrity. During the third quarter of 2013 and 2012, the Company also completed its annual impairment testing of goodwill and indefinite life intangible assets for InCon.  As a result, the Company concluded that the carrying value of its trade names exceeded the fair value by approximately $0.1 million in both 2013 and 2012. As a result, impairment expense was $0.1 million for the three and nine months ended September 30, 2013 and 2012. Additionally, as of September 30, 2013, the calculated fair value of trade secrets exceeded its carrying value by less than 5% and the calculated fair value of goodwill exceeds its carrying value by a larger amount. It should be noted that the calculated fair values on which the assessment is based are highly subjective given the early stage and transitional nature of the business.
	All of the Company’s goodwill and other intangible assets are the result of acquisitions in the human nutrition segment. The following table summarizes the changes in the carrying amount of goodwill resulting from the Company’s acquisitions (in thousands):
		WSP		Cyvex		InCon		Total
	1-Jan-13	$	—		7,050	$	936	$	7,986
	Acquisitions (1)		11,142		—		—		11,142
	30-Sep-13	$	11,142		7,050	$	936	$	19,128
	(1) On February 27, 2013, the Company acquired WSP, and the allocation of the purchase price over the fair value of the tangible and intangible assets acquired resulted in $11.1 million of goodwill.
	The following table summarizes the Company’s intangible assets, other than goodwill (dollars in thousands):

	Purchase Obligation
	In May 2012, the Company entered into a contract to purchase renewable diesel oil (“RDO”) beginning in July 2012 through the 2013 fishing season. The RDO will be utilized in one of the Company’s four fish processing plants. The contract is priced at a discount to prevailing market prices of the BTU equivalent of Platts NY Harbor 2.2% Sulfur No.6 Oil as delivery is made throughout the fishing seasons. The contract was modified in June 2013 and as of September 30, 2013, approximately 0.2 million gallons are still committed under the contract, subject to certain force majeure provisions.
	InCon Contingency
	In September 2011, the Company acquired all of the outstanding equity of InCon Processing, L.L.C., (“InCon”), a Delaware limited liability company, 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”), three 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 earnings before interest, taxes, depreciation, and amortization (“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. For the nine month periods ended September 30, 2013 and 2012, the Company has not recorded an annual earn-out estimate.
	Legal Contingencies
	On May 18, 2011, the Company’s fishing vessel, F/V Sandy Point, was involved in a collision with a commercial cargo vessel, Eurus London. As a result of the collision, the Company’s vessel sank and three Company crew members died. The Company has filed a limitation action under maritime law to limit its potential liability for the incident to $50,000, the value of the sunken vessel, in the U.S. District Court for the Southern District of Mississippi. Representatives of the three deceased crewmembers, as well as certain other crewmembers, filed lawsuits against the Company. All claims in the matter have been settled. All claims arising from the incident have been covered by the Company’s insurance program, subject to customary deductibles.
	In conjunction with the sinking of the vessel, the Company recorded a net insurance receivable of approximately $5.9 million related primarily to costs expended salvaging the sunken vessel from the Mississippi ship channel and other claims and a net receivable of $1.8 million related to the insurance value of the vessel. The $1.8 million receivable related to the vessel value was received in 2011. An additional $5.7 million related to the salvage of the vessel has been received from the Company’s primary insurance carrier. In June 2013, the Company completed the settlement of the vessel and salvage receivables with its insurance carrier.
	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 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.
	In June 2013, the Company’s subsidiary, Omega Protein, Inc., 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, Inc. will be on probation until June 2016, unless the probation period is terminated earlier by the court.
	Omega Protein had requested a waiver from the Coast Guard for its Gulf of Mexico fleet regarding the use of certain vessel equipment applicable to “ocean-going vessels” (as defined by Coast Guard regulations) that operate beyond the 12 nautical mile limit and in April 2013 the Coast Guard granted Omega Protein a partial waiver for its 2013 fishing season only that allows Omega Protein to travel, but not fish, outside 12 nautical miles of shore. Omega Protein has a pending waiver request with the Coast Guard to allow its vessels to fish beyond the 12 nautical mile limit and has been in discussions with the Coast Guard regarding this issue. If the Coast Guard does not grant this waiver, Omega Protein will have to continue restricting its 2013 fishing to within 12 nautical miles of shore or install additional equipment on its vessels which will result in additional expense.

	NOTE 12. RELATED PARTY TRANSACTIONS
	In September 2011, the Company acquired all of the outstanding equity of InCon Processing, L.L.C., (“InCon”), a Delaware limited liability company, 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”), three of whom continue to be employed by InCon and share in the management of InCon’s business. During the nine months ended September 30, 2012, the Company received a payment from the Sellers of $0.2 million to account for a final working capital adjustment in conjunction with the acquisition.
	The Sellers own and operate privately held businesses with which InCon continues to provide toll distillation services and pilot plant runs, primarily InCon Process Systems and InCon Industries. InCon recorded revenue from these related parties for the three months ended September 30, 2013 and 2012 of approximately $6,900 and $142,600, respectively, and $366,400 and $149,200, respectively, for the nine months ended September 30, 2013 and 2012. Purchases from these same related parties for the three months ended September 30, 2013 and 2012 were approximately $33,400 and $0, respectively, and $44,500 and $2,500, respectively, for the nine months ended September 30, 2013 and 2012.

	NOTE 13. RECONCILIATION OF BASIC AND DILUTED PER SHARE DATA (in thousands except per share date)
	We compute basic earnings per share 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.

	Options to purchase 238,000 and 752,000 shares of common stock were outstanding during the three and nine months ended September 30, 2012, respectively, but were not included in the computation of diluted earnings per share because the adjusted exercise prices of the options based upon the assumed proceeds were greater than the average market price of the shares during that period.

Income Tax Disclosure [Text Block]	'
	NOTE 17. INCOME TAXES
	The Company generally determines, with the exception of certain nonrecurring items, its periodic income tax benefit or expense based upon the current period income and the annual estimated tax rate for the Company adjusted for any change to prior period estimates. The estimated tax rate is revised, if necessary, as of the end of each successive interim period during the fiscal year to the Company’s current annual estimated tax rate.
	For the three months ended September 30, 2012, the income tax provision reflects an effective tax rate of 90.8%, compared to an effective tax rate of 34.6% for the quarter ended September 30, 2013.  For the nine months ended September 30, 2012, the income tax provision reflects an effective tax rate of 49.3%, compared to an effective tax rate of 34.4% for the nine months ended September 30, 2013.  The statutory tax rate of 35% for U.S. federal taxes was in effect for the three and nine months ended September 30, 2012 and 2013, respectively.  The decrease in the effective tax rates for the three and nine month periods ended September 30, 2013 is primarily a result of a nonrecurring, predominately non-deductible charge related to the U.S. Attorney investigation recognized during the three months ended September 30, 2012.  See Note 11 Commitments and Contingencies – Regulatory Matters for additional information.

	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.
	Certain amounts applicable to the prior periods have been reclassified to conform to the classifications currently followed. Specifically, the presentation of our unaudited condensed consolidated statements of comprehensive income for the three and nine months ended September 30, 2012 was revised to classify $6.2 million and $10 million, respectively, of shipping and handling related costs that were previously netted against revenue to cost of sales.  These revisions were not considered to be material, individually or in the aggregate, to previously issued financial statements. These revisions had no effect on the results of operations (net or comprehensive income), financial condition (stockholders’ equity), or cash flows in any period presented or in any previously issued financial statements.
	Additionally, for the nine months ended September 30, 2012, the Company reclassified $0.7 million of cash flows from investing activities to cash flows from operating activities related to accrued capital expenditures.  This revision was not considered to be material, individually or in the aggregate, to previously issued financial statements. The revisions had no effect on the results of operations (net or comprehensive income) or financial condition (stockholders’ equity).
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 recent acquisitions of Cyvex, InCon and WSP, the Company’s revenues also include sales of dietary supplement ingredients to the nutraceutical industry and whey protein products to the food and nutritional supplement industries. The Company recognizes revenue for the sale of its products when price is established, collectability is reasonably assured, and title and rewards of ownership of its products 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.
Inventory, Policy [Policy Text Block]	'
	Inventories
	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.
Derivatives, Policy [Policy Text Block]	'
	Energy Swap Agreements
	The Company does not enter into financial instruments for trading or speculative purposes. Omega Protein enters 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.

	The $22,700 reported in accumulated other comprehensive loss as of September 30, 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 approximately $22,100.
	The aggregate fair value of derivative instruments in gross asset positions as of September 30, 2013 and December 31, 2012 was $58,000 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. This exposure could be reduced by up to $5,000 and $0.2 million, respectively, of liabilities included in master netting arrangements with those same counterparties.
	The aggregate fair value of derivative instruments in gross liability positions as of September 30, 2013 and December 31, 2012 was $24,000 and $0, 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. This exposure could be reduced by up to $6,000 and $0, respectively, of assets included in master netting arrangements with those same counterparties.

	If, at any time, the swaps are determined to be ineffective, in whole or in part, 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 the nine months ended September 30, 2013 and 2012, the Company recognized a charge of $0.1 and $0, respectively, to cost of sales resulting from transactions associated with the prior ineffectiveness of diesel energy swaps. See Note 16 – Fair Value Disclosures for additional information.
Goodwill and Intangible Assets, Policy [Policy Text Block]	'
	Acquisitions, Goodwill and Other Intangible Assets
	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, Cyvex, InCon and WSP. On February 27, 2013, the Company purchased all of the equity interests in WSP. In the third quarter of 2011, the Company completed its acquisition of InCon Processing, L.L.C., a Delaware limited liability company. In the fourth quarter of 2010, the Company completed its acquisition of Cyvex Nutrition, Inc., a California corporation. All three acquisitions were accounted for as cash transactions using the acquisition method of accounting. Accordingly, the Company has recorded goodwill and certain other identifiable intangible assets that are more fully explained in Note 2 – Acquisition of Wisconsin Specialty Protein, L.L.C. and Note 8 – Goodwill and Other Intangible Assets.
Revenue Recognition, Percentage-of-Completion Method [Policy Text Block]	'
	Construction Contract
	Omega Shipyard engaged in a single fixed price construction contract with a third party that was completed in the fourth quarter of 2012.  The contract provided for revenue to be billed as milestones were attained based on the total estimated construction cost. The Company recognized revenue and expenses related to the contract on a percentage of completion basis based on a ratio of costs incurred to date bore to total projected costs.
	During the quarter ended June 30, 2012, Omega Shipyard revised its total estimated construction costs such that the Company expected to have gross loss upon completion.  As a result, gross profit recognized on the contract in previous quarters was reversed and the full extent of the expected loss was recognized during the quarter ended June 30, 2012.  The Company reassessed these estimates on a quarterly basis. For the three and nine months ended September 30, 2012, the Company incurred gross losses of $0.1 million and $0.5 million, respectively, with respect to the construction contract. There were no third party construction contracts during 2013.

New Accounting Pronouncements, Policy [Policy Text Block]	'
	Recently Issued Accounting Standards
	In July 2013, the FASB issued ASU No. 2013-11 which 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 is currently evaluating the impact the adoption of this guidance will have on its consolidated financial statements.
	On February 5, 2013, the FASB issued ASU No. 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. The standard requires companies to present, either in a single note or parenthetically on the face of the financial statements, the effect of significant amounts reclassified from each component of accumulated other comprehensive income based on its source and the income statement line items affected by the reclassification. The standard is effective prospectively for public entities for fiscal years, and interim periods within those years, beginning after December 12, 2012, which corresponds to the Company’s first fiscal quarter beginning January 1, 2013. The Company’s adoption of FASB ASU No. 2013-02, effective January 1, 2013, did not have an impact on the Company’s consolidated results of operations or financial position.
	In January 2013, the FASB issued ASU No. 2013-01, Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities. The standard limits the scope of balance sheet offsetting disclosures, contained in the new guidance issue in December 2011 discussed below, to recognized derivative instruments, repurchase agreements and securities borrowing and lending transactions. Effective for annual and interim periods beginning on or after January 1, 2013, the Company’s adoption of FASB ASU No. 2013-01 effective January 1, 2013 did not have an impact on the Company’s consolidated results of operations, financial position and related disclosures.
	In July 2012, the FASB issued ASU No. 2012-02 regarding subsequent measurement guidance for long-lived intangibles. This guidance is meant to reduce the cost and complexity of performing an impairment test for indefinite-lived intangible assets by simplifying how an entity tests those assets for impairment and to improve consistency in impairment testing guidance among long-lived asset categories. This guidance is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, which corresponds to the Company’s first fiscal quarter beginning January 1, 2013. The Company’s adoption of FASB ASU No. 2012-02 effective January 1, 2013 did not have an impact on the Company’s consolidated results of operations, financial position and related disclosures.
	In December 2011, the FASB issued ASU No. 2011-11, Disclosures about Offsetting Assets and Liabilities. The standard requires an entity to disclose information about offsetting and related arrangements to enable users of its financial statements to understand the effect of those arrangements on its financial position. The amendments in this update will enhance disclosures required by U.S. GAAP by requiring improved information about financial instruments and derivative instruments to help reconcile differences in the offsetting requirements under U.S. GAAP and International Financial Reporting Standards (IFRS). The amendments are effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. The Company’s adoption of FASB ASU No. 2011-11 effective January 1, 2013 did not have an impact on the Company’s consolidated results of operations or financial position.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	'
	Stock-Based Compensation
	Stock Options
	The Company has a stock-based compensation plan, which is described in more detail in Note 16 to the consolidated financial statements of the Company’s Form 10-K for the fiscal year ended December 31, 2012. The Company has issued non-qualified stock options under its stock incentive plans. The options generally vest in equal installments over three years and expire in ten years. Non-vested options are generally forfeited upon termination of employment.
	Net income for the three months ended September 30, 2013 and 2012 includes $0.2 million and $0.8 million ($0.1 million and $0.5 million after-tax), respectively, of stock-based compensation costs related to stock options. Net income for the nine months ended September 30, 2013 and 2012 includes $0.5 million and $2.3 million ($0.3 million and $1.5 million after-tax), respectively, of stock-based compensation costs related to stock options. The stock-based compensation costs related to stock options are recorded primarily in selling, general and administrative expenses in the unaudited condensed consolidated statement of comprehensive income. As of September 30, 2013 there was $0.1 million ($0.1 million after-tax) of total unrecognized compensation costs related to non-vested stock options that is expected to be recognized during the remainder of fiscal year 2013.
	Restricted Stock
	The Company has issued shares of restricted stock under the 2006 Incentive Plan. Shares of restricted stock generally vest on the third anniversary of the grant date 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 13 – Reconciliation of Basic and Diluted Per Share Data.
	During the nine month periods ended September 30, 2013 and 2012, the Company issued 58,036 and 25,000 shares of restricted stock for each period, respectively, under the 2006 Incentive Plan to employees and non-employee directors. The Company’s compensation expense related to restricted stock was approximately $0.4 million and $0.1 million ($0.3 million and $0.1 million after tax) for the three months ended September 30, 2013 and 2012, respectively, and $1.0 million and $0.4 million ($0.6 million and $0.3 million after tax) for the nine months ended September 30, 2013 and 2012, respectively, which is primarily reflected in selling, general and administrative expenses in the unaudited condensed consolidated statement of comprehensive income. As of September 30, 2013, there was approximately $1.9 million ($1.2 million after tax) of unrecognized compensation cost related to non-vested restricted stock that is expected to be recognized over a weighted-average period of 1.6 years, of which $0.4 million ($0.3 million after-tax) of total restricted stock compensation is expected to be recognized during the remainder of fiscal year 2013.
