Aquaculture

Welfare of Commercially Farmed Abalone

Abalone farming has expanded significantly as wild populations collapse; their welfare as highly mobile gastropods in intensive systems merits consideration.

Key Facts

Global abalone aquaculture produces over 100,000 tonnes annually
Abalone show nociceptive responses and active escape behavior from threats
Crowded farming conditions cause shell damage from aggressive interactions
Temperature and water quality are critical welfare determinants in abalone farming
Wild abalone populations have collapsed from overfishing in most range areas

Welfare Considerations

Abalone welfare in aquaculture is scientifically uncertain but their active behavioral responses and nociception suggest consideration is warranted. Low-density farming with good water quality reduces both welfare risk and disease-related production losses.

What You Can Do

Support research into abalone welfare and sentience
Choose farmed abalone over wild-caught given wild population collapse
Advocate for precautionary welfare standards in marine invertebrate aquaculture
Reduce abalone consumption given both conservation and welfare concerns
