Welfare of Farmed Atlantic Cod and Haddock

Atlantic cod and haddock aquaculture is growing as wild stocks recover, but these species have specific welfare needs that commercial systems are only beginning to address.

Key Facts

Wild Atlantic cod populations collapsed in the early 1990s — aquaculture has partially filled the supply gap
Cod and haddock are schooling fish with social behaviours that can be maintained in aquaculture conditions
Light manipulation is used to control spawning timing — welfare implications of artificial photoperiod are under study
Fin damage from conspecific biting is common in crowded cod aquaculture
Sea lice affect cod aquaculture as well as salmon — treatment welfare concerns are similar
Cod are slower-growing than salmon — production cycles of 2-3 years create longer welfare exposure periods
Norwegian cod aquaculture has invested substantially in welfare research relative to earlier aquaculture species

Welfare Considerations

Cod and haddock welfare in aquaculture benefits from lessons learned in salmon farming — the industry has developed with greater initial welfare awareness. Norway has been particularly active in cod welfare research, investigating social behaviour, lighting effects, and handling stress. Fin damage from biting is a persistent problem indicating crowding or nutritional stress. The longer production cycle compared to salmon means welfare problems that develop gradually have more time to accumulate. As wild cod stocks slowly recover and aquaculture expands to meet continuing demand, maintaining welfare standards as production scales is an ongoing challenge.

What You Can Do

Choose cod or haddock from certified welfare-aware aquaculture when purchasing farmed fish
Support research funding for gadoid (cod family) welfare science
Advocate for welfare standards to be included in cod aquaculture licensing conditions
Consider wild-caught sustainably certified cod where available as an alternative
Engage with retailers about their cod welfare sourcing standards
