Shrimp Biosecurity and Disease Welfare

Shrimp aquaculture faces severe disease challenges that devastate populations and raise welfare concerns for the billions of animals affected.

Key Facts

White spot syndrome virus (WSSV) and early mortality syndrome (EMS) devastate shrimp farms
WSSV has caused billions of dollars in losses and kills shrimp rapidly once introduced
Mass mortality events kill billions of shrimp in affected ponds
Biosecurity measures including water treatment and exclusion of wild shrimp carriers prevent outbreaks
Specific pathogen free (SPF) broodstock programs reduce disease introduction risk
Probiotics and immunostimulants reduce disease pressure without antibiotics
Disease outbreaks in intensive systems spread rapidly through water connections
Post-larvae testing before stocking reduces outbreak risk substantially

Welfare Considerations

Shrimp dying from WSSV experience rapid physiological deterioration as the virus destroys connective tissue throughout the body. While the welfare capacity of shrimp remains debated, mass mortality events affecting billions of animals represent suffering at a scale that demands attention even under uncertainty. Prevention through biosecurity reduces both producer losses and the mortality events that represent the most acute welfare harm in shrimp production. Intensive shrimp farming systems with inadequate biosecurity are prone to recurrent mass mortality - a cycle of poor welfare and economic loss that neither producers nor animals benefit from.

What You Can Do

Support aquaculture operations with certified biosecurity programs
Choose certified shrimp from producers with verifiable disease management standards
Advocate for disease surveillance and rapid response systems in shrimp aquaculture
Support research into disease-resistant shrimp genetics and probiotic management
Reduce consumption of shrimp from intensive systems with poor disease management
