Sustainability Certifications
MSC, ASC, BAP, Seafood Watch — what do these certifications actually verify? And what happens when none of them is available?
The Fundamental Limit of Certification
All third-party certifications are proxies. They substitute a documented, audited process for direct knowledge of the fishery, the vessel, and the handling. A certification is a credible claim that a supply chain met specific standards at the time of the last audit — it is not a guarantee that any particular fish in front of you is fresh, handled well, or correctly labeled. The strongest form of trust is direct traceability: knowing the name of the vessel, the fishing area, the date of harvest, and the person responsible. Certifications are the best available alternative when that direct traceability does not exist.
The Major Certifications
The leading international certification for wild-capture fisheries. Chain-of-custody certification traces certified fish through the supply chain. The blue oval with a fish checkmark is the retail label.
Strengths
- ✓Rigorous fishery assessments against evidence-based standards
- ✓Chain-of-custody certification required at every supply chain step
- ✓Public audit reports — anyone can review the assessment
- ✓Annual surveillance and five-year full recertification
Limitations
- •Assessment costs are significant; smaller artisanal fisheries often cannot afford it
- •Some critics argue standards are too lenient on certain trawl fisheries
- •Certification does not guarantee freshness, handling quality, or fair labor practices
- •Chain-of-custody can be gamed by unscrupulous actors in complex supply chains
The farmed seafood equivalent of MSC. Developed with input from WWF. Covers environmental impact, feed sourcing, chemical use, and labor standards across multiple farmed species.
Strengths
- ✓Addresses environmental, social, and feed-sourcing criteria
- ✓Species-specific standards (salmon, shrimp, tilapia, oysters, etc.)
- ✓Third-party audit with public disclosure
- ✓Growing retail adoption — increasingly available at major chains
Limitations
- •Variable stringency across species standards
- •Relatively newer than MSC; some standards still maturing
- •Does not guarantee product quality or taste
- •Certification is expensive, limiting access for smaller farms
A U.S.-based certification from the Global Aquaculture Alliance. Common in U.S. retail on shrimp, tilapia, and salmon. Uses a star rating (1–4 stars) based on how many supply chain steps are certified.
Strengths
- ✓Widely available at U.S. retailers
- ✓Multi-star system rewards full supply chain coverage
- ✓Covers environmental, social, food safety, and traceability
Limitations
- •Generally considered less rigorous than ASC
- •Funded by industry — independence concerns have been raised
- •Single-star certification covers only one supply chain step
Not a certification but a science-based consumer guide rating seafood as Best Choice, Good Alternative, or Avoid. The Seafood Watch app and website are widely used by consumers and buyers.
Strengths
- ✓Comprehensive, species-and-source-specific ratings
- ✓Independent — not funded by industry certification fees
- ✓Updated regularly as fishery data changes
- ✓Business partner program engages retailers and food service
Limitations
- •No on-product label verification — you have to look it up
- •Ratings can change, creating lag between advice and behavior
- •Cannot verify the actual product in front of you is from the rated source
A state-sponsored marketing program for Alaska seafood. Wild Alaska Pure / True North designations indicate Alaska-origin and wild-caught status, backed by Alaska's seafood origin requirements.
Strengths
- ✓Alaska has among the strongest fisheries management in the world
- ✓State-mandated documentation and chain of custody
- ✓Covers all major Alaska commercial species
Limitations
- •A marketing program, not an independent third-party audit
- •Says nothing about harvest method within Alaska
- •Does not address handling quality or labor standards
When No Certification Is Present
Ask for the harvest method. Hook-and-line, jig, troll, and pot are inherently selective. Knowing the method is often more informative than a certification.
Ask for the fishing area. Named states and specific fishing grounds (e.g., 'Southeast Alaska', 'Gulf of Mexico') are verifiable claims.
Ask for the vessel name or producer name. A seller who can name their harvester has a supply chain worth trusting.
Use Seafood Watch as a reference — look up the species and source before you buy.
For Alaska wild-caught: Alaska's fisheries management is world-class. Even uncertified Alaska seafood from a documented harvest is a reasonable baseline.
The Hierarchy
In order of what to trust: (1) Direct purchase from a named harvester with verifiable harvest records. (2) MSC- or ASC-certified product with intact chain of custody. (3) Non-certified product from a documented, managed fishery you can research. (4) A vague claim of “sustainable” with no verification. Certifications exist to solve the traceability gap — they are a proxy, not the thing itself.
