Sustainability and welfare are linked in seafood production. Understanding how they interact helps consumers make choices that benefit both ecosystems and individual animal welfare.
Sustainable seafood and fish welfare share significant overlap but are not identical concerns. Sustainability primarily addresses population viability and ecosystem health, while welfare focuses on individual animal experience. They intersect where overfishing causes habitat degradation that leads to starvation and suffering in wild populations, and where bycatch from unsustainable fisheries causes welfare harm. However, sustainably certified products may still involve poor welfare during capture, transport, and slaughter. Consumers seeking to maximize both sustainability and welfare need to seek products that address both dimensions rather than assuming either certification covers the other.
