European sea bass is a premium aquaculture species in the Mediterranean with welfare challenges around density, handling, and slaughter that are only beginning to be addressed by the industry.
Sea bass welfare in Mediterranean aquaculture receives less regulatory attention than salmon in northern Europe, despite comparable evidence for fish sentience and welfare-relevant responses to their farming conditions. High density causes chronic social stress and physical injury from inter-fish aggression. Live chilling slaughter — placing fish in ice slurry while conscious — causes distress before insensibility. The premium market positioning of Mediterranean sea bass creates an opportunity for welfare differentiation — consumers and restaurateurs who pay premium prices have the purchasing power to demand welfare standards commensurate with those prices.
