Today’s seafood buyers simply can’t afford to accept vague sustainability claims—they need proof they can stand behind.
As scrutiny of seafood sustainability grows, buyers demand real credentials that hold up to questions from customers, procurement teams and regulators.
Marine Stewardship Council (MSC) certification gives seafood businesses a recognized way to separate environmentally sustainable sourcing from empty green claims. For buyers, the MSC blue fish label represents a framework for helping support a healthier ocean, supply chain accountability and long-term supply confidence.
In a market where promises have come too easily, MSC carries genuine weight with its rigorous certification process built around stock, environmental impact and fishery management.
What is MSC certification?
Launched in 1997, the MSC is an independent non-profit organization established by the World Wildlife Fund and Unilever.
It was created to address the collapse of the Grand Banks cod fishery after years of intense fishing pressure. The collapse devastated coastal communities, disrupted supply and showed how quickly overfishing can affect the environment, livelihoods and seafood supplies.
Decades later, MSC certification is widely recognized as one of the most rigorous environmental standards for fishing in the seafood industry.
The fishery certification process is neither quick nor superficial. It can take up to 18 months, followed by annual audits and full reassessment every five years.
“It’s a rigorous process, and not all fisheries pass,” explains MSC’s Anthony Mastitski.
To earn the MSC label, fisheries are independently assessed by third-party auditors against a science-based framework built on three core principles:
- Sustainable fish stocks: Fishing must ensure populations remain healthy and productive over the long term.
- Minimizing environmental impact: Operations must actively reduce environmental impact by limiting bycatch, safeguarding habitats, and protecting the broader marine ecosystem.
- Effective fishery management: Fisheries must adhere to local, national, and international regulations and adapt to evolving environmental conditions.
MSC certification is more than a marketing claim; it gives buyers and consumers independent evidence that a product comes from a fishery assessed against recognized standards.
“Sustainability and traceability are core to what we do, and MSC certification helps validate that with buyers,” explains Cassie Canastra Larsen, CEO of Canastra Fishing Co.

Why MSC certification matters for seafood businesses
Sustainability now directly influences buying decisions, not just brand perception.
The global sustainable seafood market is projected to reach $33.34 billion by 2032, up from $13.12 billion in 2018. This growth marks a significant shift in consumer values when it comes to making responsible food choices.
Over 1,850 MSC-certified products are available in the U.S. and Canada. The blue fish label is now a staple in most major supermarket chains, including Whole Foods Market, Kroger, Aldi, ShopRite, Walmart, and Target.
The momentum is equally strong across the pond. In the U.K., 63% of wild-caught seafood sold in supermarkets now carries the MSC label. Spending on MSC-labeled products reached £1.7 billion ($2.3 billion) in 2025, a 14% jump from the previous period.
Foodservice has followed suit. McDonald’s and IKEA have both committed to sourcing only MSC-certified seafood for their menus.
“A lot of major retailers and international buyers will not buy certain seafood products unless they are MSC certified,” says Ben McKinney, Canastra Fishing Co. Chief Operating Officer.
“If you walk into a restaurant, retailer or wholesaler anywhere in the world and you see that something is MSC certified, you know it’s caught sustainably, processed the right way and can be traced right back to that fishery.”

The blue fish label advantages for seafood buyers
MSC certification speaks directly to buyer anxiety around seafood sourcing today.
Retailers, restaurants and institutional buyers don’t just want to know whether a product tastes good or arrives on time. They also need to know whether the sourcing story holds up and that they’re actually supporting environmentally sustainable fishing standards.
Market access and compliance
Certification opens doors with organizations that build sustainability standards into procurement as a non-negotiable.
As more governments, retailers and foodservice groups tighten expectations around sourcing, MSC-certified seafood gives distributors a stronger position in competitive bids and supplier conversations.
It also reduces the chance that a product gets excluded as rules, policies and buyer standards change.
Supply stability
Seafood supply chains already face pressure from weather, quotas, tariffs and shifting demand.
MSC certification doesn’t remove that volatility, but it does show that a fishery operates within environmentally sustainable limits and follows a management framework designed to protect the stock over time.
That matters to buyers planning menus, retail programs and long-term supply agreements.
Commercial value
MSC certification gives distributors a stronger way to sell on value, not just price.
Buyers can always find cheaper seafood. But the blue fish label gives consumers a clear reason to choose a certified product over lower-cost alternatives with weaker credentials.
MSC certification serves as a sales and marketing asset; it supports shelf differentiation, menu storytelling, ESG reporting and consumer-facing campaigns.
Supply chain transparency
Transparency has become one of the strongest trust signals in seafood. The MSC Chain of Custody supports that trust by tracking certified seafood through the supply chain. It gives buyers stronger accountability and better confidence in product origin.
“And if a customer asks us six months later where a product came from, we can trace it back through bills of lading, invoices and records right to the source,” McKinney says of Canastra Fishing Co.’s operations.
Credibility in an era of greenwashing
Vague claims like “natural,” “responsibly sourced,” or “ocean-friendly” no longer carry the same weight. What buyers need these days is proof they can show to customers.
“As buyers and consumers become more alert to greenwashing, third-party certification helps businesses show that their sustainability claims are backed by science and rigor,” says Camila Flanagan of MSC.
That credibility becomes even stronger when certification connects to a supply chain that buyers can see, understand and trust.
Turning sustainability into a strategic advantage
MSC certification has moved beyond mere compliance.
The blue fish label now supports stronger commercial conversations around trust, accountability, supply and reputation. It gives buyers something they increasingly need: a claim they can explain, document and defend.
That matters in a market where vague environmental language no longer carries the same authority.
MSC certification doesn’t replace a strong relationship with a supplier that has real control over its supply chain and product quality.
But in a seafood market shaped by risk, scrutiny and shifting expectations, MSC is a clear commercial advantage.
Canastra Fishing Co. combines a domestic fleet, transparent sourcing and MSC certification to give buyers a clear line between catch and product.
