Farmed prawns are produced in enormous numbers globally, but welfare considerations including stocking density and slaughter methods receive little regulatory attention.
Farmed prawn welfare sits at the frontier of aquaculture ethics. The scale — hundreds of billions of animals produced annually — means welfare improvements would be extraordinarily impactful even if per-animal suffering capacity is uncertain. Crowded conditions cause demonstrable stress responses, limb loss through aggression and immune compromise leading to mass disease mortality. These conditions represent both welfare failure and production failure. Welfare improvements including lower stocking density, better water quality and more humane slaughter methods simultaneously improve animal welfare and production sustainability.
