European sea bass is a popular farmed fish in Mediterranean aquaculture. Understanding its welfare needs helps consumers and producers improve farming practices.
Sea bass welfare in aquaculture reflects the broader challenge of farming highly active, schooling marine fish in intensive conditions. Sea bass in the wild swim continuously in shoals, navigating complex environments and exhibiting predator avoidance behaviour. Captive conditions that prevent normal movement and social behaviour cause chronic stress detectable through cortisol levels and behaviour. The most significant welfare interventions for sea bass farming are stocking density management, water quality maintenance, and humane pre-slaughter stunning. Consumer demand for welfare-certified Mediterranean sea bass is low but growing - purchasing ASC-certified fish and asking retailers about welfare standards drives market improvement.
