Lobsters are among the most commercially important crustaceans worldwide. Growing evidence of their capacity for pain and stress has significant implications for how they are handled, stored, and killed.
Lobster welfare is at the frontier of expanding moral consideration for invertebrates. The evidence that lobsters experience pain in a morally relevant sense has strengthened considerably: they have nociceptors, show avoidance learning, engage in wound-protective behaviour, and their stress physiology responds to noxious stimulation. The standard commercial practices of live storage in chilled tanks and boiling without prior stunning expose lobsters to potential suffering during their handling and death. Humane killing methods — electrical stunning, spiking — render lobsters neurologically insensible before killing and are technically available. The Crustacean Compassion campaign in the UK and legislative changes in Switzerland and New Zealand reflect a growing regulatory consensus that the precautionary principle should apply: if the evidence for pain is credible, we should not cause unnecessary suffering.
