Aquaculture Welfare

Farmed Abalone Welfare Standards

Abalone farming is expanding globally, and welfare standards for these complex molluscs are beginning to emerge based on their sensory biology.

Key Facts

Abalone are gastropod molluscs with a distributed nervous system
They show clear avoidance responses to noxious stimuli and tissue damage
High-density abalone farming causes physical crowding and resource competition
Water quality management is critical as abalone are highly sensitive to hypoxia
Some certification schemes are beginning to include abalone in welfare assessments

Welfare Considerations

Abalone welfare is uncertain but the precautionary principle justifies avoiding unnecessary harm. High-density conditions that cause competition and physical injury should be minimized regardless of definitively established sentience.

What You Can Do

Apply precautionary welfare principles when purchasing abalone products
Support research into abalone sensory biology and welfare indicators
Choose abalone from certified sustainable farms with quality water management
