Its emphasis is on techniques for cultivating the major farmed species, namely the giant river prawn (Macrobrachium rosenbergii). The manual also contains information of relevance to the farming of other Macrobrachium species and to the enhancement of freshwater prawn fisheries.
Farming Jumbo Freshwater Shrimp – Live Aquaponics
Freshwater Prawns are tropical animals, and as such, they require warm water to survive. A correctly engineered, constructed and well-managed pond will result in a predictable harvest of about 1,000 to 1,200 pounds per acre of a large, highly valuable 10 count/pound whole shrimp.

Large ponds are normally wider than 30 m and often drained for harvesting. If the total harvest is going to be taken at one time (batch management), the size of the pond should be influenced by the maximum weight of prawns that the market will accept at one time without price deflation.
Prawn, Freshwater – Freshwater Aquaculture - Extension
Aug 26, 2019 · Freshwater prawns are grown in earthen ponds as small as one-tenth of an acre to as large as 5+ acres. The ponds must be free of any existing fish/amphibians/turtles, or the prawn juveniles become expensive food for.

• In ponds, use shelters/substrates to increase pond surface area, improve survival of molting prawns, and allow for higher stocking densities. • Prawns reach marketable size in 4 to 5 months. Mean size at harvest is 25-35 grams. Longer culture period may be required for higher stocking densities. Stocking density for grow-out Culture ...
Proper understanding of the giant freshwater prawn, from its biology to its culture system, is necessary for the successful and optimized farming of this species. Accordingly, relevant science-based techniques on its breeding and seed production are presented in this manual.
the production of giant freshwater prawn is of high quality and safe for consumption. However, this standard does not cover for the stages of hatching and nursing of post-larval giant freshwater prawn.
The feasibility of polyculture of the freshwater prawn Macrobrachium rosenbergii and the armoured catfish or cascadura Hoplosternum littorale was tested at the Institute of Marine Affairs, Trinidad. Three grow out trials were conducted in triplicate in 0.02 ha earthen ponds.
Zhejiang province was chosen for assessment on water quality in Giant freshwater prawn (GFP), with 19 ponds in five farms used the different seed sources for culture and different geographical positions which represents for GFP culture status in Zhejiang.
