Atlantic cod aquaculture has developed significantly but faces specific welfare challenges related to cod biology and intensive production conditions.
Cod are intelligent fish with strong behavioural needs that are difficult to meet in intensive culture. Their natural foraging behaviour, involving active searching over varied substrates, is prevented in tanks and cages. High stocking densities create chronic social stress. Spawning behaviour in captivity causes aggression and injury. Welfare improvements for cod require understanding the species-specific needs better than current research allows, making investment in cod welfare science a priority for the growing industry.
