Giant freshwater prawns are farmed extensively across Asia, with welfare considerations around crowding stress and handling practices.
Freshwater shrimp welfare is affected by their territorial and aggressive nature. Crowding in intensive production systems drives chronic aggression resulting in antennae and leg loss, reduced growth, and chronic stress. Male hierarchy systems create welfare disparities where dominant blue-claw males access resources freely while smaller males suffer exclusion. Optimal stocking density management and appropriate sex ratios reduce aggression. As decapod crustaceans, freshwater shrimp now receive welfare consideration under UK law, and welfare-precautionary practices should be encouraged globally.
