Crayfish Welfare in Aquaculture and Catering

Crayfish are farmed and wild-harvested for food globally, with live boiling and poor transport conditions raising welfare concerns under the emerging framework of crustacean sentience.

Key Facts

Around 800,000 tonnes of crayfish are produced annually, mainly in China and the US
Red swamp crayfish are the dominant farmed species worldwide
Live crayfish are routinely transported for long distances outside water
The UK Animal Welfare (Sentience) Act 2022 includes decapod crustaceans
Live boiling remains the standard preparation method in most culinary traditions

Welfare Considerations

Crayfish demonstrate learning, memory and complex behaviours consistent with sentience. Their removal from water during transport and holding prior to cooking causes physiological stress. UK and EU regulatory recognition of decapod sentience suggests that live boiling should be phased out in favour of pre-stun methods. Whole-system welfare improvements from harvest to slaughter are needed.

What You Can Do

Support precautionary humane slaughter methods for crayfish in catering
Advocate for live boiling bans for decapod crustaceans in line with UK sentience recognition
Encourage catering schools to teach humane crustacean preparation techniques
Choose crayfish from suppliers who can demonstrate humane handling and slaughter
