Growing scientific evidence for crustacean sentience has prompted several countries to extend welfare protections to lobsters and crabs — transforming how these animals are treated in aquaculture and kitchens.
The welfare of lobsters and crabs sits at an important inflection point: the science now supports strong precautionary protection, but practice — in kitchens, restaurants, and aquaculture — has not caught up with the evidence. If lobsters are sentient, live boiling — which takes several minutes to cause death — may cause significant suffering. The availability of rapid mechanical stunning methods means that the welfare cost of humane slaughter is low while the potential benefit is high. Restaurants, seafood processors, and consumers all have a role in normalising humane crustacean handling. This is an area where individual practice can change quickly once the underlying science is understood.
