European sea bass is a prized aquaculture species in the Mediterranean. Intensive farming conditions, handling stress, and slaughter methods create welfare challenges that are increasingly scrutinised by welfare-conscious retailers and consumers.
Sea bass welfare in Mediterranean aquaculture is shaped by cage conditions, handling practices, and slaughter methods. The species' sensitivity to handling — shown by acute cortisol responses to even brief net operations — means that harvest procedures are welfare-critical events requiring careful management. Ice slurry without prior stunning, still common in Mediterranean production, causes bass to remain conscious for up to 9 minutes while experiencing cold shock and asphyxiation — a significant welfare failure that pre-slaughter electrical or percussion stunning can prevent. Consumer demand for higher-welfare certified sea bass creates market incentives for producers to invest in better stunning equipment and lower-density cage management.
