Farmed Cod Welfare: A Growing Aquaculture Species

Atlantic cod is an emerging aquaculture species following the collapse of wild cod fisheries. Understanding the welfare challenges of farmed cod helps ensure welfare considerations are built in from the beginning.

Key Facts

Atlantic cod aquaculture has developed primarily in Norway, Iceland, and Canada as wild stocks remain depleted.
Cod are piscivorous (fish-eating) and require high-protein diets — their feed requirements have significant wild fish input.
Vertebral compression and spinal deformity have been identified as welfare problems in farmed cod, linked to nutrition and stocking density.
Cod show temperature-dependent behavior — welfare in farming must account for their thermal preference range.
Unlike salmon, cod are less domesticated and may be more prone to stress responses from handling and confinement.

Welfare Considerations

Farmed cod represents an opportunity to build welfare standards into an emerging aquaculture sector before poor practices become entrenched. The welfare challenges — spinal deformity, stress responses, feed requirements — are known, and addressing them at the outset is far more effective than retrofitting welfare onto established systems. Norway's experience with salmon welfare provides both lessons and infrastructure that can be applied to cod. Building welfare science into cod aquaculture development from the beginning, rather than as an afterthought, could establish a higher baseline than the salmon industry achieved.

What You Can Do

Support research institutions developing welfare standards for emerging aquaculture species.
Choose cod products from farms with documented welfare programs.
Advocate for welfare requirements to be built into aquaculture licensing for new species.
Support sustainable wild fishery recovery as an alternative to intensive cod farming.
