Farmed Prawn Harvest Welfare

Harvest methods for farmed prawns have significant welfare implications. Current practices often expose prawns to prolonged stress and delayed death.

Key Facts

Global farmed prawn production exceeds 5 million tonnes annually
Harvest typically involves pond draining and crowding before collection
Prawns are often kept alive in ice slurries or ice alone before processing
Evidence suggests decapod crustaceans including prawns have nociceptive capacity
Better harvest methods such as electrical stunning before icing are under development

Welfare Considerations

Prawns experience significant welfare challenges at harvest. Crowding triggers physiological stress responses. Immersion in ice without prior stunning causes slow chilling that may involve aversive experience. Emerging research on decapod sentience has prompted regulatory changes in some jurisdictions and growing industry interest in humane slaughter. Consumer demand can drive faster adoption of better practices.

What You Can Do

Choose certified prawns from producers using higher welfare harvest practices
Support organisations researching and promoting humane crustacean slaughter
Ask retailers about welfare standards in their prawn supply chains
Reduce prawn consumption or substitute with lower-welfare-risk options where possible
