 Before a seafood product can carry the MSC eco-label, the fishery must acquire the MSC Fisheries certification.Additionally, all companies in the supply chain that take ownership of the product including distributors, wholesalers, manufacturers, pack houses, traders, retailers, catering organizations and restaurants must acquire the MSC Chain of Custody Certification.Critics condemn the Marine Stewardship Council for certifying specific fisheries that may be in trouble, harmful to the environment, or where there is a lack of information available.
