Atlantic cod aquaculture is developing as wild stocks recover, with early welfare lessons from existing operations informing more humane production standards.
Atlantic cod aquaculture is at an early stage where welfare standards can be built into the industry before large-scale consolidation makes reform difficult. The species presents specific welfare challenges: cod are highly gregarious and schooling disruption during handling is particularly stressful; they are susceptible to bacterial and viral diseases under high-density conditions; and their seasonal reproductive cycle creates management challenges. Early adoption of welfare best practices — appropriate stocking densities, minimizing handling frequency, disease prevention through water quality management, and pre-slaughter stunning — establishes industry norms that persist as production scales. The parallel wild stock recovery offers an opportunity to monitor interactions between farmed escapes and wild fish with welfare implications for both populations.
