Abalone are marine gastropods farmed at scale in several countries, and their welfare in intensive aquaculture settings raises questions as evidence of mollusc sentience grows.
The sentience of abalone and other gastropods remains scientifically uncertain, but precautionary welfare consideration is increasingly recommended. Abalone show clear responses to noxious stimuli and high stocking densities increase stress indicators. As evidence about mollusc capacity for pain-like states develops, welfare standards in abalone aquaculture may need to be strengthened.
