Welfare concerns for land crabs raised in aquaculture and harvested commercially, including evidence of pain and stress.
The welfare of farmed land crabs occupies a significant gap between growing scientific evidence and inadequate regulatory protection. Research shows crabs respond to noxious stimuli in ways consistent with pain experience, show avoidance learning, and exhibit stress responses under poor holding conditions. Commercial practices including live boiling without prior stunning cause prolonged suffering. As aquaculture expands to meet demand, welfare standards have not kept pace. Consumers and regulators increasingly need to account for crustacean sentience in policy and purchasing decisions.
