Critical analysis of current aquaculture certification schemes — including ASC, BAP, and organic standards — examining their welfare provisions, gaps, and the path toward meaningful fish welfare inclusion.
Current aquaculture certification schemes were largely developed when fish sentience was more contested and welfare science less developed. The result is a certification landscape that provides reasonable assurance on environmental and social criteria but limited protection for individual fish welfare. Consumers selecting certified seafood to improve fish welfare are often getting less than they assume. The path forward requires certification bodies to integrate fish welfare science into their standards — covering stocking density, water quality targets, enrichment, disease burden assessment, and humane slaughter as minimum welfare requirements. Some certification schemes are moving in this direction, but progress is slow relative to the scale of welfare concern. Consumer advocacy and market pressure can accelerate this change.
