Farmed Atlantic Cod Welfare: Recovery and Aquaculture Challenges

Atlantic cod aquaculture has faced significant challenges, and understanding the welfare needs of this species is important for any sustainable revival of cod farming.

Key Facts

Atlantic cod populations collapsed due to overfishing in the 1990s, devastating wild fisheries
Cod aquaculture has been attempted but faces challenges including disease and cannibalism
Cod are active, social fish that require appropriate social groupings and space
Skeletal deformities are a welfare concern in farmed cod, often linked to nutrition
Temperature management is critical as cod are adapted to cold, North Atlantic waters
Cod show measurable stress responses to handling, crowding, and poor water quality

Welfare Considerations

Atlantic cod in aquaculture face welfare challenges that contributed to the commercial difficulties of the industry. High rates of cannibalism in intensive systems cause injury and mortality. Skeletal deformities linked to nutritional deficiencies affect a significant proportion of farmed fish. Like other carnivorous fish species, cod have high oxygen requirements and suffer measurably in overcrowded, poor-quality water. Any revival of cod aquaculture must incorporate welfare standards addressing these known problems from the outset.

What You Can Do

Choose wild-caught cod from certified sustainable fisheries over poorly managed sources
Support aquaculture welfare research that informs responsible cod farming if it develops
Advocate for welfare standards to be incorporated into any new cod aquaculture licensing
Reduce overall seafood consumption and support ocean recovery programs
