Aquaculture certification schemes vary enormously in their welfare requirements, making evaluation of specific schemes important for welfare-conscious consumers.
The aquaculture certification landscape requires navigation by welfare-conscious consumers because schemes differ fundamentally in their welfare coverage. A certified product may have strong environmental credentials but minimal welfare standards, or vice versa. For fish welfare specifically, the key variables — stocking density, water quality, slaughter method, and disease management — are addressed to varying degrees by different schemes. Consumers who want to make welfare-based choices in aquaculture products need access to comparative scheme evaluations that distinguish environmental from welfare standards.
