Aquaculture welfare certification schemes provide a framework for improving farmed fish welfare, but the variation in standards, auditing rigour, and species coverage means not all labels provide equal assurance.
Certification provides a floor of welfare standards that uncertified production may not meet, but the floor varies considerably between schemes. Some labels address primarily environmental sustainability with minimal welfare content. Consumers choosing certified fish products are making a better welfare choice than uncertified alternatives in most cases, but the limitations of current certification - particularly for emerging species and in-water welfare measurement - mean certification is a step toward improved welfare rather than a guarantee of optimal outcomes.
