What MSC certification means
The blue MSC label is used for seafood that comes from fisheries assessed against the MSC Fisheries Standard. The purpose of the standard is to help ensure that fishing is environmentally responsible and that fish stocks and marine ecosystems can remain healthy over time.
Science-based standards
The MSC Fisheries Standard is built on scientific requirements for sustainable fishing. It is reviewed regularly to reflect international best practice in fisheries management and marine science.
What certified fisheries must show
Fisheries that want certification must show that fish stocks are sustainable, that the wider marine ecosystem is protected, and that management systems are strong enough to respond to changing conditions.
Independent assessment
MSC does not certify fisheries by itself. Certification decisions are made by independent third-party assessors who review evidence, consult relevant stakeholders, and publish their findings. Once a fishery is certified, it is reviewed every year.
Traceability through the supply chain
MSC certification also depends on traceability. Certified seafood must be kept separate from non-certified seafood through the supply chain so that products carrying the MSC label can be traced back to a certified source.
Why this matters
For fisheries and seafood businesses, MSC certification can help provide verified proof of sustainability and support access to markets that require independently certified seafood products.
