Abalone farming is a premium aquaculture sector raising welfare questions about molluscan sentience and the welfare implications of harvesting methods.
Abalone welfare sits in an intermediate uncertainty zone: more complex than bivalves, less clearly sentient than fish. Their behavioral responses to noxious stimuli and moderately complex nervous systems create welfare uncertainty that warrants precautionary consideration. Current scientific consensus holds that gastropod sentience is unlikely but possible, making welfare practices that minimize potential suffering reasonable. Water quality management and minimizing handling stress are welfare interventions that also benefit production outcomes. For consumers, abalone represents a higher welfare uncertainty than bivalves but lower than vertebrate aquaculture species.
