What conditions are needed for raising giant river prawns?
Summary A giant river prawn (Macrobrachium rosenbergii) farm needs to be built on flat terrain with convenient power supply. The suitable width of a prawn pond is 40-60 m, the water depth is about 1.5 m, and feeding platforms with a width of no less than 2 m need to be built. Loam and clay can be chosen as the farming soil, and unpolluted lake water and river water are used as the water source. The dissolved oxygen content in the pond needs to be maintained at 3-5 mg/L, the pH at 7-8.5, and the water temperature at about 25-30°C. During this period, auxiliary facilities need to be well equipped.
