The blue fish label

Only seafood from fisheries that meet our strict standard for sustainability can be sold with the MSC blue fish label. It's our way of making sure you know that your seafood purchase is good for the oceans because it's wild, sustainable, and traceable back to a certified fishery.

Rigorous.

Each MSC certified fishery is independently assessed by third-party experts on its specific impacts to wild fish populations and the ecosystems they are part of. The third-party independent assessment team is made up of experts in fisheries management. These teams consult with stakeholders interested in the fishery, from retailers to NGOs to governing bodies. This ensures that all information and perspectives are considered and that outcomes are based on the most current science. To be certified, the fishery must meet 28 detailed criteria across three principles. This rigorous process can take up to 18 months.

Impartial.

Certification by an independent team of experts is necessary to avoid conflicts of interest so the process remains impartial and credible. As such, the MSC does not decide what fisheries get certified; that's up to the independent certifiers.

Traceable.

From ocean to plate, MSC certified seafood is tracked, kept separate from non-certified products, and is clearly labeled so it can be traced back to a certified sustainable source. Every company at every step of the supply chain must be certified and audited annually to ensure these strict rules are adhered to.

Transparent.

Once certified, fisheries are audited annually to ensure that they are maintaining the required level of sustainability and meeting any conditions of improvement. All assessments, decisions, audits, and reports are published on fisheries.msc.org.

Truthful.

An independent study found that as much as 30% of seafood is mislabeled. Whether intentional or not, seafood mislabeling (seafood fraud)   is unfair to consumers. Regular DNA testing has shown that products with the MSC blue fish are correctly labeled so you can trust that the seafood is what the packaging or menu says it is.

Fisheries improving

As well as fishing healthy populations, fisheries must show they are managing their impacts on habitats and other marine species.
