European sea bass (Dicentrarchus labrax) is one of the Mediterranean's most important farmed fish species, with growing attention to welfare standards in a competitive industry.
Mediterranean sea bass farming has expanded rapidly with little welfare regulation, creating an industry where economic pressures consistently override welfare considerations. High stocking densities reduce production costs but impose chronic stress on fish that are intelligent enough to suffer meaningfully from it. Slaughter practices are a particular concern — ice slurry stunning followed by live exsanguination can involve prolonged consciousness. More humane approaches including percussion stunning or electrical stunning before killing are available but require capital investment. Consumers and certification bodies are the primary drivers of change, as regulatory pressure in the EU has been slow to reach aquaculture. Greek and Turkish operations face significant welfare gaps compared to Norwegian salmon farms, which have more developed welfare standards.
