Shrimp aquaculture faces devastating disease outbreaks that cause mass mortality and potential suffering. Disease prevention through biosecurity and health monitoring improves both welfare and farm viability.
Shrimp disease outbreaks represent massive welfare events: millions of animals dying from infection over days causes suffering at a scale that is difficult to comprehend. Mass mortality from disease in pond aquaculture is typically preceded by sublethal suffering including reduced feeding, abnormal behavior, and physiological stress responses. Prevention through biosecurity, SPF breeding stock, probiotics, and density management is the most welfare-aligned approach because it prevents suffering rather than managing the aftermath of disease outbreaks. The welfare dimension of shrimp disease is often framed purely in economic terms, but recognizing the suffering involved provides additional moral urgency to implementing effective prevention programs.
