Farmed Cod Welfare Challenges and Industry Development

Atlantic cod farming has expanded but faces significant welfare challenges distinct from salmon aquaculture.

Key Facts

Atlantic cod aquaculture produces around 25,000 tonnes annually, primarily in Norway
Cod show strong cannibalism at early life stages requiring careful size grading
Spinal deformities affect 5-15% of farmed cod, causing chronic pain and reduced mobility
Cataracts are more prevalent in farmed than wild cod, possibly linked to diet
Cod respond strongly to crowding stress with pronounced cortisol elevation

Welfare Considerations

Cod welfare presents different challenges from salmon: higher aggression, size variation within cohorts and deformity rates require active management. Spinal deformities and cataracts cause chronic welfare problems that reduce quality of life throughout the production cycle. Selective breeding for welfare traits and improved early-life husbandry can address these issues.

What You Can Do

Ask about welfare standards and deformity monitoring when purchasing farmed cod
Support aquaculture certification schemes that include cod-specific welfare criteria
Advocate for mandatory welfare monitoring and reporting in cod aquaculture
Support research into nutritional and genetic approaches to reduce deformities
