Organization, Consolidation and Presentation of Financial Statements Disclosure and Significant Accounting Policies [Text Block]	'
	1	BASIS OF PRESENTATION
	The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information pursuant to the instructions to Form 10-Q and Regulation S-X of the Securities and Exchange Commission (SEC). These interim condensed consolidated financial statements are unaudited and, in the opinion of management, include all adjustments (consisting of normal recurring adjustments and accruals) necessary to present fairly the Condensed Consolidated Balance Sheets, Condensed Consolidated Statements of Operations, and Condensed Consolidated Statements of Cash Flows for the periods presented in accordance with GAAP. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. The results of operations for the interim periods are not necessarily indicative of the results to be expected for the full fiscal year. The Condensed Consolidated Balance Sheet as of March 31, 2014 was derived from the audited financial statements. These condensed consolidated financial statements and notes should be read in conjunction with the Company’s audited consolidated financial statements for the year ended March 31, 2014, contained in the Company’s annual report on Form 10-K as filed with the SEC on June 27, 2014.
	The accompanying condensed consolidated financial statements include the accounts of Cyanotech Corporation and its wholly owned subsidiary, Nutrex Hawaii, Inc. (“Nutrex Hawaii” or “Nutrex”, collectively the “Company”). All significant intercompany balances and transactions have been eliminated in consolidation.
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosures of any contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the periods reported.  Management reviews these estimates and assumptions periodically and reflects the effect of revisions in the period that they are determined to be necessary.  Actual results could differ from those estimates and assumptions.
	Recent Accounting Pronouncements
	In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers", which will supersede most existing U.S. GAAP revenue recognition guidance. This new standard requires an entity to recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which an entity expects to be entitled in exchange for those goods or services. In addition, ASU 2014-09 contains expanded disclosure requirements relating to the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. ASU 2014-09 is effective for fiscal periods beginning after December 15, 2016 and permits the use of either the full retrospective or cumulative effect transition method. Early adoption is not permitted. We have not yet selected a transition method and are evaluating the impact that this new standard will have on our consolidated financial statements.

	The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying value of such assets may not be recoverable. Recoverability of these assets is measured by a comparison of the carrying amount to forecasted undiscounted future cash flows expected to be generated by the asset. If the carrying amount exceeds its estimated future cash flows, then an impairment charge is recognized to the extent that the carrying amount exceeds the asset’s fair value. Management has determined no asset impairment existed as of September 30, 2014. The Company recognized a loss on disposal of assets in the amount of $3,000 and $13,000 for the three and six months ended September 30, 2014, respectively. The Company recognized a loss on disposal of assets in the amount of $21,000 and $26,000 for the three and six months ended September 30, 2013, respectively.
	The Company has capitalized $57,000 and $112,000 of interest for the three and six months ended September 30, 2014, respectively. $55,000 and $98,000 of interest was capitalized for the three and six month period ended September 30, 2013.

	Term Loan Agreements
	The Company executed a loan agreement with a lender providing for $5,500,000 in aggregate credit facilities (the “Loan”) secured by substantially all the Company’s assets, pursuant to a Term Loan Agreement dated August 14, 2012 (the “Loan Agreement”). The Loan Agreement is evidenced by promissory notes in the amounts of $2,250,000 and $3,250,000, the repayment of which is partially guaranteed under the provisions of a United States Department of Agriculture (“USDA”) Rural Development Guarantee program (the “Guarantees”). The proceeds of the Loan will be used to acquire new processing equipment and leasehold improvements at its Kona, Hawaii facility.
	The provisions of the Loan require the payment of interest only for the first 12 months of the term; thereafter, and until its maturity on August 14, 2032, the obligation fully amortizes over nineteen (19) years. Interest on the Loan accrues on the outstanding principal balance at an annual variable rate equal to the published Wall Street Journal prime rate (3.25% at September 30, 2014) plus 1.0% and is adjustable on the first day of each calendar quarter and fixed for that quarter. At no time shall the annual interest rate be less than 5.50%. The Loan has a prepayment penalty of 5% for any prepayment made prior to the first anniversary of the date of the Loan Agreement, which penalty is reduced by 1% each year thereafter until the fifth anniversary of such date, after which there is no prepayment penalty. The balance under this Loan was $5,328,000 at September 30, 2014. Proceeds from the Loan are classified as restricted cash until drawn upon to acquire new processing equipment and leasehold improvements.
	The Loan includes a one-time origination and guaranty fee totaling $214,500 and an annual renewal fee payable in the amount of 0.25% of the USDA guaranteed portion of the outstanding principal balance as of December 31 of each year, beginning December 31, 2012. The USDA has guaranteed 80% of all amounts owing under the Loan. The Company is subject to financial covenants and customary affirmative and negative covenants. The Company was in compliance with these financial covenants at September 30, 2014.
	The Company has three equipment loans with John Deere credit providing for $103,000 in equipment financing; these loans are payable in 48 equal monthly principal payments. At September 30, 2014 and March 31, 2014, the total outstanding combined balance was approximately $29,000 and $42,000, respectively. The equipment loans mature at various dates between May 2015 and June 2016. The loans are at a 0% rate of interest and are net of unamortized discount of $1,000 and $1,000 at September 30, 2014 and March 31, 2014, respectively.
	In September 2011, the Company executed a Term Loan Agreement with Nissan Motor Acceptance Corporation providing for $23,000 in equipment financing, secured by the equipment. The Term Loan has a maturity date of September 13, 2016 and is payable in 60 equal monthly principal payments. The interest rate under this Term Loan is 0%. Imputed interest at a rate of 2% (cash discount offered by seller) has been recorded and is being amortized as interest over the term of the loan. The balance outstanding under the Term Loan was $9,000 and $12,000 at September 30, 2014 and March 31, 2014, respectively, less the unamortized discount of $200 and $300 at September 30, 2014 and March 31, 2014, respectively.
	Future principal payments under the term loan and capital lease agreements as of September 30, 2014 are as follows:

	7	COMMITMENTS AND CONTINGENCIES
	On September 12, 2012, the Company entered into an agreement with ThyssenKrupp Industrial Solutions (USA), Inc. (“TKIS”), formerly Uhde Corporation of America, for the purchase of supercritical carbon dioxide extraction equipment to be used in the processing of its natural astaxanthin (“Equipment”). Pursuant to the terms of the agreement, TKIS will build, ship and provide assistance in installing the Equipment. The Equipment, which was originally scheduled for delivery approximately 14 months from the date of the agreement, is now scheduled for a delivery in the third quarter of this fiscal year. The Company will pay TKIS an aggregate of $3,222,000 for the equipment and services, of which $645,000 remains unpaid as of September 30, 2014. Progress payments through September 30, 2014 of $2,577,000 have been classified in construction in progress in the consolidated balance sheet.
	The Company is subject to legal proceedings and claims from time to time in the ordinary course of business. Although management cannot predict with certainty the ultimate resolution of legal proceedings and claims asserted against the Company, management does not believe that any currently pending legal proceeding to which the Company is a party is likely to have a material adverse effect on its business, results of operations, cash flows or financial condition.
	We have previously disclosed the negative effect of the legal costs of one pending patent lawsuit against the Company and a related administrative proceeding initiated by the Company to challenge the validity of the patent which is the subject of the lawsuit.–––’–’ Our legal costs grew significantly in the first quarter of this fiscal year due to costs related to development of reports by our medical and economic experts, the extension of discovery and deposition deadlines, and costs related to preparation for the oral hearing with the Patent Trial and Appeal Board (“PTAB”) on our Inter Partes Review (see Risk Factors, pages 14-15, and discussion of increase in Operating Expenses, page 16-17).
	Patent litigation and Inter Partes Review matters :
	On June 29, 2012, U.S.Nutraceuticals LLC, d/b/a Valensa International [“ Valensa ”] and The Board of Trustees of the University of Illinois [the “ Patent Owner ”] filed a lawsuit against Cyanotech Corporation and Nutrex Hawaii, Inc. in the U.S. District Court for the Middle District of Florida, Ocala Division (the “ Litigation ”) primarily alleging infringement of U.S. patent no. 5,527,533   2 (the “ ’533 Patent ” or “ Patent ”).
	In an effort by the Company to accelerate a determination of the invalidity of the ‘533 Patent, the Company petitioned the PTAB of the U. S. Patent and Trademark Office on June 28 and 29, 2013 to conduct an administrative review of the validity of the ‘533 Patent, as challenged in our Petition; PTAB instituted an Inter Partes Review of 18 of the 27 Claims within the ‘533 Patent on December 19, 2013 (“ IPR ”). The Patent Owner is the respondent in the IPR.
	1Form 10-K, Item 3 – Legal Proceedings, dated March 31, 2014 (filed June 27, 2014), Form 8-K, Item 8.01 – Other Events, dated June 30, 2013 (filed August 26, 2013); and Forms 10-Q for the quarter ended September 30, 2013 (see Item 2 – Management’s Discussion and Analysis, Operating Expenses, page 16); and Form 10-Q/A (filed February 14, 2014) for the quarter ended December 31, 2013 (see Item 2 – Management’s Discussion and Analysis, Operating Expenses, page 16).
	(a) Factual Basis : (i) The product involved in the Litigation and the Inter Partes Review is a natural health supplement called astaxanthin (“ Astaxanthin ”) which the Company grows and harvests, and in different forms markets, and sells to wholesalers, retailers and consumers. Valensa is Patent Owner’s licensee of certain rights under the ‘533 Patent and was one of the Company’s domestic wholesale customers for several years until the expiration of its supply contract with us and after it was given a 12-month notice in December 2011 that our Company would no longer sell bulk product to Valensa and to other domestic bulk customers. Valensa manufactures, markets and sells products containing Astaxanthin to wholesalers and retailers.
	(ii) All Claims within the ‘533 Patent are “method of treating” claims. The ‘533 Patent is generally described in the “Field of Invention” section as a method for retarding and ameliorating certain specified diseases, injuries or damage (“condition”) by administering a therapeutically-effective amount of Astaxanthin to an individual suffering from the condition. The ‘533 Patent includes 27 Claims pertaining to: retinal damage; retinal injury; neuronal damage to a retina; age-related macular degeneration; ischemic or intraocular pressure-related disease of a retina; inflammatory disease of a retina; a free radical-induced injury to the central nervous system or comprised of a traumatic or an ischemic injury; a degenerative disease; or a degenerative central nervous system disease of a brain or spinal cord. Patent Owner and Valensa assert that all 27 Claims under the ‘533 Patent are valid. The Company asserts that all 27 Claims are invalid and therefore the entire ‘533 Patent is invalid.
	(iii) Patent Owner and Valensa allege in the Litigation, but the Company denies, that the scope of the ‘533 Patent method claims extends to, and its 27 Claims apply to, our manufacturing, marketing and sales of Astaxanthin as a nutritional supplement. Patent Owner and Valensa allege, but the Company denies, that the Claims of the ‘533 Patent broadly cover “eye health,” although those particular words do not appear in the ‘533 Patent. The Company alleges that whether one or all Claims within the ‘533 Patent are determined to be valid, no Claim was infringed by any of our manufacturing, marketing or sales of Astaxanthin products and we have not induced anyone to infringe the Patent.
	(iv) Fact discovery concluded in July 2014. Expert discovery and advice of counsel discovery will conclude in November 2014. Based upon new evidence discovered in the course of the discovery process, the federal court granted leave to the Company to file both Third Amended Counterclaims (filed on September 16, 2014) and Fourth Amended Counterclaims (filed on October 6, 2014). Plaintiffs responded to the Fourth Amended Counterclaims on October 17, 2014. The patent in dispute expired October 27, 2014. Trial remains scheduled for the Court's docket on March 2, 2015.
	(b) Relief Sought by Patent Owner and Valensa : (i) a declaration of patent infringement; (ii) a declaration that the patent infringement was intentional; (iii) a preliminary and a permanent injunction barring us and our employees and affiliates from infringing the ‘533 Patent      3 ; (iv) damages for infringement, plus interest and plus treble damages for willful infringement; (v) an award of attorneys’ fees and costs of suit, plus interest; and (vi) any further relief awarded by the Court.
	(c) Relief Sought by Company : (i) a declaration of invalidity and unenforceability based on original patentability or on patent misuse; (ii) a declaration of non-infringement; (iii) a declaration of unfair competition under Hawaii law and under the Federal Lanham Act; (iv) a determination that this case is exceptional , thereby entitling the Company to recover its attorneys’ fees; (v) an award of compensatory damages to Company; (vi) an award of statutory damages under Hawaii law; (vii) an order that Patent Owner and Valensa pay over all of their unlawful profits to Company; (viii) an order to Patent Owner and Valensa to destroy all materials (e.g., advertising materials) in the possession or control of either Patent Owner and Valensa which have been determined to be false; (ix) an injunction against Patent Owner and Valensa from continuing any methods of competition declared to be in violation of Hawaii law or the Lanham Act; and (x) any further relief awarded by the Court.
	The Court records of the Litigation 4 and the filings in the Inter Partes Review 5 can be found as indicated in the respective footnotes. An oral hearing before PTAB was held on July 16, 2014.

	8	SHARE-BASED COMPENSATION
	The Company accounts for share-based payment arrangements using fair value. If an award vests or becomes exercisable based on the achievement of a condition other than service, such as for meeting certain performance or market conditions, the award is classified as a liability. Liability-classified awards are remeasured to fair value at each balance sheet date until the award is settled. The Company currently has no liability-classified awards. Equity-classified awards, including grants of employee stock options, are measured at the grant-date fair value of the award and are not subsequently remeasured unless an award is modified. The cost of equity-classified awards is recognized in the statement of operations over the period during which an employee is required to provide the service in exchange for the award, or the vesting period. All of the Company’s stock options are service-based awards, and because the Company’s stock options are “plain vanilla,” as defined by the U.S. Securities and Exchange Commission in Staff Accounting Bulletin No. 107, they are reflected only in equity and compensation expense accounts.
	As of September 30, 2014, the Company had three equity-based compensation plans: the Independent Director Stock Option and Restricted Stock Grant Plan (the “2014 Directors Plan”); the 2005 Stock Option Plan (the “2005 Plan”); and the 2004 Independent Director Stock Option and Stock Grant Plan (the “2004 Directors Plan”). The Company’s equity based compensation plans provide for the awarding of stock options and shares of restricted common stock for eligible employees, certain outside consultants and independent directors.
	On August 28, 2014, the Company’s shareholders approved the 2014 Directors Plan. This plan authorizes the Board of Directors to provide additional incentive to the Company’s independent directors through equity based compensation in the form of stock options and restricted stock. Awards under the 2014 Directors Plan are limited to the authorized amount of 350,000 shares. As of September 30, 2014, there were 333,439 shares available for grant under the 2014 Directors Plan.
	Under the 2005 Plan, eligible employees and certain independent consultants may be granted options to purchase shares of the Company’s common stock. The shares issuable under the 2005 Plan will either be shares of the Company’s authorized but previously unissued common stock or shares reacquired by the Company, including shares purchased on the open market.  As of September 30, 2014, there were 395,148 options available for grant under the 2005 Plan.
	The 2004 Directors Plan was terminated on August 28, 2014. As a result, no additional awards will be issued under this plan
	The following table presents shares authorized, available for future grant and outstanding under each of the Company’s plans:
			As of September 30, 2014
			Authorized			Available		Outstanding
	2014 Plan			350,000			333,439		16,561
	2005 Plan			2,075,000			395,148		1,472,686
	2004 Directors Plan			—			—		12,000
	Total			2,425,000			728,587		1,501,247
	All stock option grants made under equity-based compensation plans were issued at exercise prices no less than the Company’s closing stock price on the date of grant. Options under the 2005 Plan and 2014 Directors Plan were determined by the Board of Directors or the Stock Option and Compensation Committee of the Board in accordance with the provisions of the respective plans.  The terms of each option grant include vesting, exercise, and other conditions are set forth in a Stock Option Agreement evidencing each grant. No option can have a life in excess of ten (10) years.  The Company records compensation expense for employee stock options based on the estimated fair value of the options on the date of grant using the Black-Scholes option-pricing model. The model requires various assumptions, including a risk-free interest rate, the expected term of the options, the expected stock price volatility over the expected term of the options and the expected dividend yield. Compensation expense for employee stock options is recognized ratably over the vesting term. Compensation expense recognized for options issued under the 2005 Plan was $160,000 and $353,000 for the three and six months ended September 30, 2014, respectively. Compensation expense recognized for options issued under the 2005 Plan was $176,000 and $354,000 for the three and six months ended September 30, 2013, respectively. Compensation expense recognized for restricted stock issued under the 2014 Directors Plan was $78,000 for the three and six months ended September 30, 2014. Compensation expense recognized for restricted stock and options issued under the 2004 Directors Plan was $51,000 for the three and six months ended September 30, 2013, respectively. All share-based compensation has been classified as general and administrative expense.
	A summary of option activity under the Company’s stock plans for the six months ended September 30, 2014 is presented below:
	Option Activity		Shares			Weighted Average		Weighted Average		Aggregate

Income Tax Disclosure [Abstract]	'
Income Tax Disclosure [Text Block]	'
	9	INCOME TAXES
	We utilize our estimated annual effective tax rate to determine our provision (benefit) for income taxes for interim periods. The income tax provision (benefit) is computed by taking the estimated annual effective tax rate and multiplying it by the year to date pre-tax book income (loss). We recorded income tax expense of $325,000 and $229,000 for the three months ended September 30, 2014 and 2013, respectively. Our effective tax rate was 63.4% and 68.4% for the quarters ended September 30, 2014 and 2013, respectively. We recorded an income tax expense (benefit) of ($426,000) and income tax expense of $335,000 for the six months ended September 30, 2014 and 2013, respectively. Our effective tax rate was 65.4% and 71.1% for the six months ended September 30, 2014 and 2013, respectively.
	The effective tax rate for the three and six months ended September 30, 2014 differs from the statutory rate of 34% as a result of the state taxes (net of federal benefit) and permanent differences.
	The Company is subject to taxation in the United States and two state jurisdictions. The preparation of tax returns requires management to interpret the applicable tax laws and regulations in effect in such jurisdictions, which could affect the amount of tax paid by the Company. Management, in consultation with its tax advisors, files its tax returns based on interpretations that are believed to be reasonable under the circumstances. The income tax returns, however, are subject to routine reviews by the various taxing authorities.  As part of these reviews, a taxing authority may disagree with respect to the tax positions taken by management (“uncertain tax positions”) and therefore may require the Company to pay additional taxes. Management evaluates the requirement for additional tax accruals, including interest and penalties, which the Company could incur as a result of the ultimate resolution of its uncertain tax positions. Management reviews and updates the accrual for uncertain tax positions as more definitive information becomes available from taxing authorities, completion of tax audits, expiration of statute of limitations, or upon occurrence of other events.
	As of September 30, 2014, there was no liability for income tax associated with unrecognized tax benefits. The Company recognizes accrued interest related to unrecognized tax benefits as well as any related penalties in interest income or expense in its consolidated condensed statements of operations, which is consistent with the recognition of these items in prior reporting periods.
	With few exceptions, the Company is no longer subject to U.S. federal, state, local, and non-U.S. income tax examination by tax authorities for tax years before 2009.

Earnings Per Share [Abstract]	'
Earnings Per Share [Text Block]	'
	10	EARNINGS PER SHARE
	Basic earnings per share is computed on the basis of the weighted average number of common shares outstanding. Diluted earnings per share is computed on the basis of the weighted average number of common shares outstanding plus the potentially dilutive effect of outstanding stock options using the “treasury stock” method.
	Reconciliations between the numerator and the denominator of the basic and diluted earnings per share computations for the three months ended September 30, 2014 and 2013 are as follows:
			Three Months Ended September 30, 2014
			Net Income			Shares		Per Share

	Effect of dilutive securities — Common stock options			—			224		—
	Diluted income per share		$	106			5,699	$	0.02
	Reconciliations between the numerator and the denominator of the basic and diluted earnings per share computations for the six months ended September 30, 2014 and 2013 are as follows:
			Six Months Ended September 30, 2014
			Net Income			Shares		Per Share
			(Numerator)			(Denominator)		Amount

	Effect of dilutive securities — Common stock options			—			185		—
	Diluted income per share		$	136			5,655	$	0.02
	Basic and diluted loss per share are the same in periods of a net loss, because common share equivalents are anti-dilutive when a net loss is recorded. Diluted earnings per share does not include the impact of common stock options totaling 632,642 and 672,568 for the three months ended September 30, 2014 and 2013, respectively, and 632,642 and 565,416 for the six months ended September 30, 2014 and 2013, respectively, as the effect of their inclusion would be anti-dilutive.
