Farmed Cod Welfare: Challenges in Atlantic Cod Aquaculture

Atlantic cod farming presents distinct welfare challenges including stress responses, crowding effects and disease susceptibility that require evidence-based management.

Key Facts

Atlantic cod aquaculture has expanded as wild cod stocks remain depleted from historic overfishing
Cod show strong stress responses to handling, netting and transport, elevating cortisol significantly
High stocking densities increase aggression, fin damage and susceptibility to bacterial infections
Cod have complex social hierarchies and show competition-related welfare impacts in crowded conditions
Vibriosis and furunculosis are major disease concerns in cod farms affecting fish health and welfare
Welfare indicators for cod are less developed than for salmon, creating assessment challenges

Welfare Considerations

Farmed cod experience significant welfare challenges related to their stress physiology, social complexity and disease vulnerability. Compared to salmon, welfare science for cod lags behind, meaning many producers rely on practices not yet validated for this species. Advancing species-specific welfare standards and indicators is an important research priority for the growing cod farming industry.

What You Can Do

Choose seafood from farms with independently audited welfare standards
Support organisations developing species-specific welfare indicators for cod
Encourage retailers to source cod from farms with documented lower stocking densities
Advocate for mandatory welfare assessment requirements in aquaculture regulations
Support wild cod stock recovery efforts to reduce pressure for intensive aquaculture
