Crabs and lobsters are increasingly recognized as sentient animals capable of pain, raising important welfare questions for boiling live and the seafood industry.
Evidence that decapod crustaceans experience pain has accumulated rapidly, with studies showing behavioral responses to noxious stimuli, physiological stress responses, and learning to avoid harmful experiences. The precautionary principle argues for adopting more humane killing methods while scientific certainty develops. Electrical or mechanical stunning before killing appears to cause rapid unconsciousness and represents a welfare improvement over boiling live.
