The Marine Stewardship Council (MSC) is a non-profit organisation which aims to set standards for sustainable fishing. Fisheries that wish to demonstrate they are well-managed and sustainable compared to the MSC's standards are assessed by a team of Conformity Assessment Bodies (CABs). . The mission of the MSC is to use its ecolabel, for which the MSC receives royalties for licensing it to products, and fishery certification program to recognise and reward sustainable fishing practices.
