Salmon Welfare Labelling: What Certification Schemes Tell Consumers

Farmed salmon is sold under numerous certification and labelling schemes, but these vary enormously in their welfare requirements. Understanding what labels mean helps consumers make more informed welfare choices.

Key Facts

Atlantic salmon aquaculture produces over 2.5 million tonnes annually, primarily in Norway, Chile, Scotland, and Canada
Common certification schemes include ASC (Aquaculture Stewardship Council), GLOBALG.A.P., and organic labels
ASC focuses primarily on environmental impact — its welfare requirements are limited compared to environmental criteria
RSPCA Assured in the UK is the most welfare-specific certification for farmed salmon, with standards on stocking density and slaughter
Organic salmon standards vary by country — some prohibit sea lice chemicals but do not address stocking density or slaughter
No certification scheme currently requires pre-slaughter stunning for farmed salmon, though some producers adopt it voluntarily

Welfare Considerations

Salmon welfare labelling is a landscape of confusion for consumers. Environmental certifications like ASC and MSC address sustainability metrics — bycatch, feed sourcing, escapes — but have minimal welfare content. RSPCA Assured (UK) and equivalent welfare-specific labels address stocking density, enrichment, sea lice management, and handling practices more directly. Organic labels vary widely: EU organic salmon must be at lower stocking densities than conventional, but this does not guarantee good welfare outcomes in all domains. Pre-slaughter stunning — the most welfare-critical intervention — is not required by any major certification body as of 2024, although RSPCA Assured requires it for some operations. Consumers who want to support the best available welfare outcomes should look for RSPCA Assured or equivalent welfare-specific certifications, and contact their preferred brands to ask about stunning practices.

What You Can Do

Look for RSPCA Assured or equivalent welfare-specific labels when buying farmed salmon in the UK
Contact salmon brands you purchase from and ask whether they stun fish before slaughter
Support Aquaculture Stewardship Council campaigns to strengthen welfare content in their certification standard
Reduce farmed salmon consumption or choose plant-based alternatives when welfare-certified options are unavailable
