Growing evidence for pain and stress responses in crabs, lobsters, and other decapod crustaceans is reshaping welfare debates around live boiling and the seafood trade.
The recognition of decapod crustacean sentience in UK law is a landmark moment for animal welfare, extending legal protection to animals long excluded from welfare consideration. The evidence for pain and negative experience in crabs and lobsters is now sufficient to warrant substantial changes in handling and killing practices across the seafood industry. Electrical stunning before killing, rapid killing methods, and avoidance of stress-inducing practices such as live transport without anaesthesia are practical welfare improvements available now, without waiting for philosophical certainty about crustacean consciousness.
