Abalone Welfare in Aquaculture

Abalone are increasingly farmed gastropod molluscs whose welfare capacity is an emerging area of scientific and ethical consideration.

Key Facts

Abalone are marine snails farmed primarily in South Africa, China, and Australia
Global abalone aquaculture production exceeds 150,000 tonnes annually
Abalone have simple nervous systems but show aversive responses to noxious stimuli
High stocking density causes growth reduction and potential stress in farmed abalone
Oxygen management is critical as abalone are sensitive to hypoxia

Welfare Considerations

Abalone welfare science is at an early stage, with uncertainty remaining about their capacity for pain and suffering. However, they demonstrate aversive responses to harmful stimuli and show physiological stress responses to poor water quality and crowding. Applying the precautionary principle suggests that management practices minimising potential harm should be preferred.
