Aquaculture Certification and Welfare Standards

Aquaculture certification schemes vary enormously in their welfare provisions, making informed consumer choices increasingly complex but important.

Key Facts

Global aquaculture production exceeds wild capture fisheries in some categories and is growing rapidly
The Aquaculture Stewardship Council (ASC) and Best Aquaculture Practices (BAP) are leading certification schemes
Welfare standards in aquaculture certification vary significantly between schemes and species
Key welfare issues include stocking density, water quality, disease management, and slaughter methods
Salmon welfare certification has advanced further than certification for most other farmed species
A RSPCA Assured certification for salmon represents one of the most comprehensive welfare standards available

Welfare Considerations

Aquaculture welfare certification represents a significant advance in bringing welfare considerations into seafood supply chains, but the quality and comprehensiveness of standards varies enormously. Some certifications focus primarily on environmental sustainability with minimal welfare provisions; others specifically address water quality, stocking density, injury prevention, and slaughter method requirements. The welfare of farmed fish is a genuine moral concern supported by growing evidence for fish sentience. Certifications that require stunning before slaughter - currently rare but advancing - represent the gold standard for farmed fish welfare. Consumer choices and retailer policies that prioritize welfare-credible certification schemes drive market incentives for improved on-farm standards.

What You Can Do

Look for RSPCA Assured (for salmon) or equivalent high-welfare certifications when choosing farmed fish
Ask your supermarket which welfare standards they require from their farmed fish suppliers
Prioritize fish certified by schemes that specifically address stocking density and slaughter method
Support development of improved aquaculture welfare standards through engagement with certification bodies
Reduce consumption of farmed fish from regions with weak welfare regulation where certified alternatives exist
Engage with retailers to request improved welfare certification requirements from their aquaculture suppliers
