Multiple certification schemes cover farmed seafood, but their welfare standards vary widely. Understanding what labels do and do not guarantee helps consumers make informed choices.
Seafood certification has expanded rapidly, but welfare coverage remains inconsistent. Environmental sustainability and welfare are distinct dimensions: a certification can require low environmental impact while saying nothing about stocking density, slaughter methods, or disease management. The most welfare-relevant currently available certifications for farmed fish include RSPCA Assured in the UK and some organic standards that limit stocking density. Consumers seeking welfare-positive seafood choices should prioritize these over purely environmental labels, while also reducing overall consumption to limit demand on intensive systems.
