Biosecurity failures in shrimp aquaculture cause mass mortality events that represent simultaneous welfare and economic disasters.
Shrimp biosecurity welfare involves the intersection of disease prevention and individual animal welfare in a species whose sentience remains scientifically contested. The welfare significance of disease events depends on assumptions about shrimp capacity for suffering, but mass mortality events involving billions of animals across the shrimp farming industry warrant precautionary welfare consideration regardless of certainty about consciousness. Prevention-focused biosecurity that reduces disease pressure also reduces the scale of potential suffering, aligning commercial and welfare interests effectively.
