Welfare Considerations

Fish welfare certification is a rapidly evolving field as scientific understanding of fish sentience and welfare needs develops. The most credible schemes are moving toward outcome-based welfare indicators — measurable signs of good or poor welfare in the fish themselves — rather than relying solely on input standards. Certification programs increasingly cover pre-slaughter stunning, emergency slaughter protocols, and transport welfare. Consumers choosing certified products create market incentives for farms to improve welfare standards across the supply chain.
