Aquaculture Certification Gaps: What Current Standards Miss

Despite significant progress, aquaculture certification schemes have important welfare gaps that leave substantial suffering unaddressed.

Key Facts

The Aquaculture Stewardship Council (ASC) is the leading global certification scheme but welfare requirements vary significantly by species
Most current certification focuses on environmental sustainability rather than animal welfare as the primary criterion
Key welfare gaps include: no mandatory pre-slaughter stunning requirements for most species, limited stocking density limits based on welfare evidence, inadequate positive welfare indicators
ASC certification covers farmed salmon, shrimp, tilapia, and other species but welfare depth varies considerably
RSPCA Assured in the UK provides stronger welfare requirements for salmon specifically but limited coverage of other species
Many species including carp, catfish, and tilapia lack species-specific welfare standards in any certification scheme
Third-party auditing frequency under most schemes is insufficient to detect welfare problems that fluctuate seasonally
Consumer awareness of what certification schemes actually require is low — the gap between perception and reality is significant

Welfare Considerations

Aquaculture certification is valuable but imperfect. Current schemes have moved the industry toward better practices on environmental metrics and on a subset of welfare indicators for higher-profile species. However, significant welfare gaps remain: billions of fish are slaughtered annually without effective stunning in certified operations; positive welfare indicators are rarely required; species coverage is uneven; and auditing depth is insufficient to catch fluctuating welfare conditions. The most welfare-conscious consumers need to go beyond the presence or absence of a label and understand what a specific certification actually requires for the species they are purchasing. Advocacy for strengthening existing standards is more impactful than individual choice alone.

What You Can Do

Research what specific welfare requirements apply to the certification label on the seafood you purchase
Support campaigns by Fish Welfare Initiative and RSPCA to strengthen welfare requirements in aquaculture certification
Advocate for mandatory pre-slaughter stunning requirements to be added to all major aquaculture certification schemes
Engage with ASC and other certification bodies to push for stronger species-specific welfare standards
Ask retailers which certification scheme covers their aquaculture products and what that scheme requires for welfare
Reduce aquaculture consumption for uncertified or weakly certified species while supporting stronger certification development
