Freshwater Prawn Farming
The giant freshwater prawn or also known as Shrimp farming; Is suitable for cultivation in tropical and subtropical climates. A freshwater prawn farm is an aquaculture business designed to raise and produce freshwater prawns or shrimp for human consumption.
Freshwater prawn farming shares many characteristics with, and many of the same problems as, marine shrimp farming.
How to Start Freshwater Shrimp/Prawn Farming?
1. Obtain proper permits and/or licenses if you intend to sell farmed shrimp
For better information visit the nearest agricultural department.
2. Prepare your grow-out pond or ponds
Ponds must be in an area not prone to flooding and unaffected by runoff from areas utilizing pesticides. Ponds should have a depth of 2 to 5 feet and a surface area of 1 to 5 acres. Employ skimmers, filters, and aerators to keep the water quality optimal.
Fertilizing the pond will ensure plenty of natural food for the shrimp in the form of algae. The pond should maintain a temperature of at least 70 degrees Fahrenheit and a pH between 6.5 and 9.5. Your tank should also have a high concentration of oxygen.
3. Purchase the best shrimp from a hatchery
Hatching is the most difficult part of shrimp farming and should not be attempted by individuals without extensive knowledge of shrimp biology and brackish water quality maintenance.
4. Acclimate the shrimp to their new environment
Slowly replace the water they were transported in with water from the grow-out pond.
5. Stock the first grow-out pond
Macrobrachium rosenbergii are aggressive, and a hierarchy is formed among males. Stocking densities need to be kept low to prevent cannibalism and stunted growth. The pond should allow for at least 4 square meters per prawn. Lower densities result in larger shrimp.
6. Feed the shrimp once they reach 5 grams
Smaller shrimp will receive enough nourishment from small pond organisms. A pelleted feed of at least 38% protein works well. Shrimp can be fed twice daily, with a larger feeding at dusk, as shrimp are nocturnal.
How long does it take for freshwater prawns to grow?
The duration of the grow-out period depends on the water temperature of the ponds, and the time generally is 120 to 150 days in central Mississippi. Prawns could be grown year-round if you can find a water source that provides a sufficiently warm temperature for growth. When we talk about harvesting, Generally from the shrimp hatch to the harvest takes about 7 to 8 months.
