This prawn spends its adult life in fresh or brackish waters. Larval development however requires brackish water of 8 to 22 ppt salinity.

Species of the freshwater prawn genus Macrobrachium are distributed throughout the tropical the tropical and subtropical zones of the world.

They are found in most inland freshwater areas including lakes, rivers, swamps, irrigation ditches, canals and ponds, as well as in estuarine.

Freshwater prawns farming are popular now. Breeders of Macrobrachium are developed and maintained in earthen ponds. The freshwater prawn is expected to attain sexual maturity in four of five months.

Large berried breeder prawns are collected and stocked in well-aerated concrete tanks and large un-berried females are separated in another tank.
