European sea bass is a premium farmed fish produced primarily in the Mediterranean. Establishing welfare standards for this species is an important and underdeveloped area of aquaculture reform.
Sea bass aquaculture welfare sits in a regulatory gap: welfare science and standards have focused primarily on salmon, leaving Mediterranean farmed species without species-specific guidance. The welfare challenges are partially shared with salmon (stocking density, slaughter methods, disease) and partially distinct: sea bass social dynamics, temperature tolerance, and feeding behaviour require species-specific management approaches. The premium market positioning of sea bass in European retail creates consumer access to welfare labelling that could drive improvement if welfare standards were established and enforced. The aquaculture welfare reform movement needs to expand beyond salmon to encompass all major farmed species; sea bass represents an important and tractable next step.
