Soft-shell crab production involves harvesting crabs immediately after moulting, raising distinct welfare questions about the moulting process and post-moult handling.
Soft-shell crab production raises welfare questions at multiple points in the production cycle. Confinement in shedding tanks in small individual compartments restricts natural behaviour and social interaction. The moulting process itself is a period of acute vulnerability - newly moulted crabs are soft, fragile, and have limited ability to escape or defend themselves. Immediate harvest after moulting prevents recovery and normal hardening, and the subsequent handling, freezing, or live sale all occur when crabs are physiologically most vulnerable. As crustacean sentience research develops, these welfare concerns become increasingly important considerations for the soft-shell crab industry.
