Abalone are gastropod molluscs farmed for luxury seafood markets globally. Their welfare status is uncertain, but emerging research on mollusc nociception and stress responses is beginning to inform more precautionary management approaches.
Abalone welfare sits in a similar uncertain zone to other molluscs — simple enough nervous systems that sentience is genuinely debated, complex enough behaviour that complete dismissal of welfare concern seems premature under a precautionary approach. Their escape responses to harmful stimuli indicate nociceptive function; whether this involves subjective experience remains unresolved. Production at scale in conditions of crowding, handling stress, and disease creates potential welfare impacts that precautionary management should address even under uncertainty. Minimum disruption handling, disease prevention through water quality management, and rapid chilling before processing represent low-cost, high-certainty welfare improvements that can be implemented regardless of the resolution of sentience debates.
