Aquaculture Welfare

Disease Management in Farmed Shrimp and Welfare

Disease outbreaks in intensive shrimp farming cause massive mortality events and require antibiotic use that has global health implications; disease prevention through welfare-conscious management reduces both impacts.

Key Facts

White spot syndrome virus has caused billions of dollars of losses in Asian shrimp farming
Antibiotic use in shrimp farming has contributed to antimicrobial resistance in human pathogens
Stressed shrimp show higher disease susceptibility, creating a welfare-production virtuous cycle
Biosecure intensive systems with water treatment reduce disease incidence but increase energy use

Welfare Considerations

Disease in farmed shrimp represents a compounding welfare problem: the conditions of intensive culture that maximise stress also maximise disease susceptibility, and disease outbreaks cause mass mortality events of potentially sentient animals. Welfare-conscious management that reduces crowding, improves water quality, and minimises stress markers simultaneously reduces disease incidence — creating an alignment between shrimp welfare and farm sustainability.

What You Can Do

Support shrimp products certified by schemes with disease management and welfare standards
Advocate for antibiotic monitoring and reporting requirements in shrimp aquaculture
Raise awareness that disease prevention in shrimp farming has both animal welfare and human health implications
