Shrimp Welfare Biosecurity Advanced

How biosecurity practices in shrimp farming affect both disease burden and individual shrimp welfare.

Key Facts

Disease outbreaks including White Spot Syndrome and Early Mortality Syndrome cause mass shrimp deaths
Mortality events from disease cause significant suffering before death in affected shrimp
Biosecurity measures including water treatment, stock screening, and pond disinfection reduce disease
Good biosecurity reduces the need for antibiotics, which has welfare and public health implications
Stress from poor water quality and overcrowding increases susceptibility to disease in farmed shrimp
Welfare and biosecurity share common ground: healthier shrimp with lower stress have better disease resistance

Welfare Considerations

Biosecurity in shrimp farming is simultaneously an economic and welfare issue. Disease outbreaks cause mass mortality events in which shrimp experience physiological crisis before death. While shrimp welfare science is still developing, evidence of nociception and stress responses supports the case for minimizing disease-driven mortality and the prolonged physiological stress preceding it. Farms that invest in robust biosecurity — water management, stock health screening, disease surveillance — protect their production and reduce the suffering associated with disease events.

What You Can Do

Support shrimp certification schemes that include biosecurity and health management as welfare criteria
Choose shrimp from operations with documented disease management and antibiotic stewardship records
Advocate for shrimp welfare research that examines disease-related suffering alongside production metrics
Encourage biosecurity training programmes for smallholder shrimp farmers in producing countries
Raise consumer awareness of the welfare dimensions of shrimp disease management
