A growing number of aquaculture certification schemes address fish and shellfish welfare, but standards vary enormously in scope, rigour and verification - understanding what they cover helps consumers make informed choices.
The welfare rigour of aquaculture certification varies dramatically - some schemes provide meaningful welfare protection while others primarily address environmental or food safety concerns with minimal welfare content. Consumers looking for welfare assurance should seek schemes that specifically address stocking density, water quality, handling procedures, stunning at slaughter, and disease management - not just sustainability indicators. The challenge is that many high-welfare practices are invisible in supermarket labelling. Building industry-wide welfare standards that go beyond individual certification schemes requires regulatory frameworks alongside market incentives.
