Farmed Atlantic Cod Welfare: A Developing Aquaculture Sector

Atlantic cod farming is a developing sector whose welfare considerations are being integrated into production systems as the industry matures.

Key Facts

Atlantic cod populations collapsed from intensive fishing leading to interest in aquaculture as an alternative supply route
Cod farming is commercially practiced in Norway, Iceland, and Canada with production growing but still small relative to historical wild catch
Cod are cannibalistic and aggressive with size variation in cohorts creating significant welfare risks from inter-individual predation
Appetite and feeding behavior assessment provides a non-invasive welfare indicator for cod welfare monitoring
Vaccination programs for bacterial diseases including vibriosis have reduced antibiotic use improving both welfare and antibiotic resistance outcomes

Welfare Considerations

Atlantic cod welfare in aquaculture involves challenges around cannibalism management requiring careful size grading, handling stress during transfers, disease management, and slaughter welfare. Compared to salmon, cod welfare science is less developed but is receiving growing attention as the sector expands. Best practice includes careful stocking density management, regular grading to reduce size variation and cannibalism risk, minimal handling protocols, and pre-slaughter stunning. The welfare science base for cod is developing alongside the industry itself.

What You Can Do

Choose farmed cod products from certified producers where welfare standards are available
Support aquaculture welfare research covering developing sectors including cod aquaculture
Advocate for welfare standards to be integrated into cod aquaculture regulation from the industry's early development
Ask retailers about welfare certification requirements in their farmed cod supply chains
