Disease outbreaks in farmed shrimp cause massive mortality and welfare harm, and disease prevention through better management is both a welfare and a production priority.
Shrimp disease represents one of the largest scale welfare problems in animal agriculture by number of animals affected, though shrimp sentience remains debated. If shrimp experience suffering — as precautionary welfare frameworks suggest — then disease-related mortality in crowded pond systems represents enormous preventable harm. Disease prevention through better husbandry is aligned with both welfare and production economics: healthier shrimp with lower crowding stress in well-managed water quality experience less disease. The transition from open pond systems with high disease pressure to biosecure systems with better environmental control improves welfare while protecting producers from catastrophic losses. Antibiotic reduction also benefits broader One Health goals.
