Abalone are farmed extensively in China, South Africa, and Australia, with welfare considerations that remain almost entirely absent from production standards and consumer awareness.
Abalone welfare sits at the frontier of animal welfare science: molluscs with centralized nervous systems capable of pain-like responses, yet receiving essentially no welfare attention from producers, regulators, or consumers. The question of abalone sentience is genuinely uncertain, but the evidence for nociception — the capacity to detect and respond to noxious stimuli — suggests precautionary welfare consideration is warranted. Commercial farming conditions including high density and suboptimal water quality cause measurable physiological stress responses. Developing welfare standards for abalone requires investing in sentience research and translating findings into practical farming guidelines.
