Acute hepatopancreatic necrosis disease (AHPND) devastates shrimp aquaculture with massive welfare impacts on surviving and dying animals.
AHPND represents a convergence of individual welfare harm and industry catastrophe. Mass mortality events impose dying on enormous numbers of animals simultaneously. Surviving shrimp in contaminated ponds experience chronic disease stress. The ecological and economic pressure to produce shrimp at minimal cost creates conditions where AHPND risk is systematically underestimated. Prevention through certified pathogen-free postlarvae and robust biosecurity provides the most effective welfare and production protection simultaneously. The welfare incentive for disease prevention is aligned with producer economics — in this case, market and welfare interests point toward the same management improvements.
