Disease outbreaks in shrimp aquaculture cause massive mortality and significant individual welfare harm while also devastating producer livelihoods across Asia and Latin America.
Shrimp disease welfare sits at the intersection of uncertainty about shrimp sentience and certainty that disease-driven mass mortality events involve extreme physiological stress. Disease outbreaks in shrimp farms kill billions of individuals under crowding conditions, often through bacterial or viral pathology that causes progressive physiological failure. The precautionary welfare argument supports production practices that reduce disease risk — better water quality management, lower stocking density, biosecure facilities — as welfare improvements even under uncertainty about shrimp experience. These practices also improve economic outcomes for producers by reducing catastrophic losses, creating strong alignment between welfare and production incentives. Consumer demand for certified shrimp from operations with documented disease management and biosecurity standards can drive adoption of more welfare-positive production approaches.
