Crabs are caught and processed in large numbers globally. Evidence for crustacean sentience is growing, raising significant welfare questions about current fishing and processing practices.
The evidence for crab sentience has strengthened considerably in recent years, making current industry practices ethically problematic. Live boiling — the most common method of killing crabs — likely causes significant suffering if crabs experience pain as the LSE review suggests. Crabs may take several minutes to die when boiled alive. Live dismemberment for processing is even more concerning. Despite legal protections in some jurisdictions, enforcement for wild-caught crabs remains difficult. The scale of crab fishing globally means that if crabs do experience suffering, the welfare impact is enormous. Consumer awareness and demand for more humane processing methods is the most direct lever for change.
