Aquaculture Welfare

Aquaculture: Shrimp Welfare and Slaughter Methods

The welfare of farmed shrimp at slaughter is a largely neglected issue despite the enormous numbers involved globally.

Key Facts

Global farmed shrimp production exceeds 5 million tonnes annually - billions of individual animals
Common slaughter methods include live chilling in ice, dry asphyxiation, and direct processing while alive
Decapod crustacean sentience is recognised in UK law, raising questions about shrimp welfare
Electrical stunning has been developed and validated for some crustacean species
Welfare standards for shrimp slaughter do not exist in any major certification scheme

Welfare Considerations

The welfare status of shrimp at slaughter is uncertain but the precautionary principle and their legal recognition as potentially sentient animals warrants consideration. The scale of shrimp production - billions of animals - means even small improvements in slaughter welfare have enormous aggregate impact. Developing and validating humane slaughter methods for shrimp and incorporating them into certification requirements is an urgent welfare priority.
