Farmed Prawn Disease Management and Welfare

Disease is the primary cause of suffering and economic loss in farmed prawns, requiring integrated management approaches that prioritise welfare.

Key Facts

White spot syndrome virus causes catastrophic losses in prawn farms globally
Early mortality syndrome caused by Vibrio bacteria kills prawns in juvenile phase
Prophylactic antibiotic use in some regions contributes to AMR
Probiotics and biosecurity reduce disease without compromising welfare
High stocking density increases disease transmission and stress

Welfare Considerations

Disease in prawns causes significant suffering and mass mortality. Prevention through biosecurity, reduced stocking density, and good water quality is better for welfare than treatment. The evidence for prawn sentience is growing, strengthening the welfare case for disease prevention.
