Norway lobsters are caught in large quantities by trawl and creel fisheries. As decapod crustaceans, they are probably sentient, making welfare during capture and storage an ethical priority.
Norway lobsters are caught primarily by otter trawl, a method that subjects them to physical compression, crowding, temperature shock, and air exposure during the sorting process. These are significant welfare stressors for an animal now legally recognized as probably sentient in the UK. Trawled langoustines show elevated hemolymph lactate — a stress biomarker — after capture, and survival rates during live transport are reduced by these acute stresses.
Creel fishing is the welfare-superior alternative. Langoustines enter traps voluntarily and remain in a more stable, underwater environment until retrieval. Creel-caught langoustines show better post-capture condition and survival rates, and the method avoids the physical trauma of trawling. Consumer demand for creel-caught langoustines can drive a welfare-positive shift in fishing methods.
Live-held langoustines require appropriate temperature, dissolved oxygen, and stocking density management to maintain welfare. Rapid chilling — using ice slurry or cold water to bring temperature to near-freezing — is widely used and reduces nociceptive capacity before handling or killing. This is the most practically implementable welfare improvement in current commercial practice.
