Atlantic Cod Welfare in Aquaculture: A Developing Industry

Atlantic cod aquaculture is an emerging industry in Norway and Iceland, with welfare questions that parallel those for salmon but with important species differences.

Key Facts

Farmed cod production remains small compared to salmon but is growing as wild stocks recover slowly
Cod are highly susceptible to stress-induced mortality, particularly during grading and handling
Cod aggregate during spawning and show complex social behaviour not yet accounted for in farm systems
Cod maturation in sea cages causes welfare problems including reduced growth and feed intake
Recirculating aquaculture systems are being developed for cod as a welfare and biosecurity improvement

Welfare Considerations

Cod farming faces species-specific welfare challenges including high stress sensitivity during handling, premature sexual maturation that causes welfare and production problems, and disease susceptibility. Cod in sea cages that mature prematurely spend energy on reproduction rather than growth and show increased aggression and reduced feed intake. Light manipulation to prevent maturation has welfare implications through disruption of natural cycles. The species sensitivity to handling stress means that routine farm operations including grading and vaccinating carry higher welfare costs per individual than in salmon. Welfare standards for cod farming are being developed but lag behind those for salmon.

What You Can Do

Support development of species-specific welfare standards for farmed cod
Choose cod products with aquaculture certification where available
Advocate for welfare assessment requirements in aquaculture licensing for new species
Support research into cod-specific welfare indicators and husbandry optimisation
Reduce consumption of uncertified intensively farmed cod from systems without welfare standards
