Traditional fisheries for crabs, lobsters, whelks and other marine invertebrates are now subject to growing welfare scrutiny following the recognition of crustacean sentience in UK legislation.
The legal recognition of decapod crustacean sentience in the UK creates an ethical tension with the continued practice of boiling live lobsters and crabs - a form of killing that, if these animals do experience pain, causes significant suffering. The evidence for crustacean nociception and aversive experience has moved from speculative to substantial in recent years. Commercial fisheries and the food service industry face a genuine welfare question that the legal framework has not yet resolved with regulatory requirements. Welfare-conscious approaches use electrical stunning immediately before killing, ice slurry as a first step, or HPP methods that cause more rapid death. Consumer and industry awareness is driving gradual change.
