Aquaculture certification schemes vary considerably in their welfare standards, with consumers and buyers needing to understand what different labels actually represent for farmed fish.
Aquaculture certification landscape is complex and imperfect, with different schemes covering different species, geographic regions, and welfare criteria with varying rigor. The challenge for welfare-conscious consumers is that environmental certification schemes like ASC have been the primary reference point, despite covering welfare incompletely. Schemes with stronger welfare requirements — including RSPCA Assured in the UK — tend to have more limited geographic and species coverage. A practical approach is to prioritize certification schemes with explicit welfare criteria over purely environmental labels while recognizing that no current scheme provides comprehensive welfare assurance across all aquaculture species. The trajectory is positive as welfare standards are progressively incorporated into existing certification frameworks.
