Shore crabs and other intertidal crustaceans face welfare challenges from collection for bait and food, habitat degradation, and the growing scientific evidence for crustacean sentience.
Recognition of crustacean sentience under UK law represents a significant shift in how shore crabs and related species must be considered ethically. The welfare implications of intertidal collection — rough handling, transport in buckets without water, use as live bait — require reassessment in light of the evidence for crab sentience. Commercial crab fishing welfare is also relevant: trap crowding, long soak times without feed, rough handling, and live boiling all represent potential welfare concerns for beings with demonstrated capacity for aversive experience. Humane killing methods including spiking (pithing) are now recommended by welfare organisations for all decapod crustaceans.
