Farm Animal Welfare

Farmed Abalone Welfare

Abalone farming is growing globally to meet demand and relieve pressure on wild stocks, raising questions about the welfare of these marine molluscs in captivity.

Key Facts

Abalone are marine gastropods with complex behaviours including photosensitivity and aggregation
Farmed abalone require very specific water quality, temperature, and algae supply
Overcrowding causes stress, disease, and reduced growth in abalone farms
The sentience of abalone is debated; they lack central nervous systems like vertebrates
Processing methods vary widely and welfare during slaughter has received little attention

Welfare Considerations

Even where abalone sentience remains uncertain, the precautionary principle suggests minimising potential suffering through good husbandry and humane processing methods.

What You Can Do

Choose abalone products from certified and monitored farms where possible
Support research into mollusc welfare and sentience
Advocate for welfare considerations in aquaculture regulation for all farmed species
