Marine protected areas that restrict fishing and other damaging activities allow wildlife populations to recover and provide refuges where animals experience fewer anthropogenic welfare threats, supporting both conservation and welfare goals.
Marine protected areas benefit animal welfare by reducing the density and frequency of welfare threats animals encounter. Fish in well-enforced no-take zones experience lower rates of bycatch mortality and injury, reduced vessel noise disturbance, and habitat protection that ensures food availability. Cetaceans and marine mammals in protected zones benefit from reduced vessel strike and noise pollution risk. The welfare benefit of MPAs extends beyond protected boundaries as healthier ecosystems support population recovery that reduces starvation and competition-related welfare harms.
