Farmed Shrimp Post-Harvest Welfare

The welfare of farmed shrimp at harvest is receiving growing attention as their capacity for pain and distress is increasingly supported by scientific evidence.

Key Facts

Global shrimp aquaculture produces around 5 million tonnes annually - one of the largest aquaculture sectors
Shrimp are decapod crustaceans sharing nervous system features with crabs and lobsters
The UK Animal Welfare (Sentience) Act 2022 extends consideration to decapod crustaceans
Common harvest practices including chilling on ice and boiling live shrimp involve significant welfare risk
Electrical stunning systems for crustaceans are available and increasingly used in high-welfare facilities

Welfare Considerations

The welfare evidence for decapod crustaceans including shrimp has strengthened considerably. They possess nociceptors, show avoidance learning, and respond to analgesics - indicators of pain experience. Conventional harvest practices - live chilling, boiling, and transport in air - cause significant distress if shrimp are sentient. The UK's legal recognition of decapod sentience creates a policy imperative to develop welfare standards for commercial shrimp production. Humane slaughter methods including electrical stunning exist and are used by some high-welfare producers. Consumer demand for welfare-certified shrimp can drive industry adoption of better practices.

What You Can Do

Support certification schemes requiring humane slaughter for farmed shrimp
Advocate for welfare standards to be included in shrimp aquaculture certification programs
Reduce or eliminate shrimp consumption pending development of welfare-certified supply chains
Support research into commercially viable humane slaughter methods for decapod crustaceans
Ask supermarkets and restaurants about their shrimp welfare sourcing policies
