Aquaculture welfare certification schemes vary in their standards and rigor, with important differences in what they actually require from certified producers.
Aquaculture certification welfare quality ranges from comprehensive (RSPCA Assured salmon including specific welfare outcome requirements) to minimal (environmental certifications that include welfare as a secondary consideration). Consumer confusion between environmental certification schemes and welfare certification is widespread - an ASC or MSC label primarily indicates environmental sustainability criteria with minimal welfare requirements, not high welfare standards. RSPCA Assured and Global G.A.P. with welfare module represent stronger welfare guarantees. The most welfare-positive purchasing choice requires understanding what each certification actually requires rather than assuming all certifications are equivalent.
