Disease outbreaks in shrimp farming cause mass mortality events affecting billions of animals. Understanding disease welfare implications drives better management practices in global shrimp aquaculture.
Mass disease events in shrimp ponds represent welfare emergencies affecting billions of potentially sentient animals simultaneously. Shrimp affected by WSSV and other pathogens exhibit abnormal swimming, reduced feeding, and physical deterioration before death — a process that given evidence of crustacean nociception suggests potential suffering at enormous scale. Beyond mortality events, chronic disease pressure in overcrowded ponds causes ongoing stress and immune compromise. Biosecurity improvements including pond preparation, water treatment, controlled inputs, and reduced stocking densities address both welfare and commercial sustainability. Better disease management is simultaneously a welfare and economic imperative for the industry.
