Requirements to Grow Freshwater Prawns
A water temperature greater than 68F for approximately 100 days is necessary for pond growout. This water temperature requirement is achieved in the S.E. United States as far North as Southern Ohio. Locations farther North will not have adequate water temperatures for pond production unless heated water is used from geothermal or from discharged water from power plants.
The growout of prawns to market size (30-100g) is best accomplished by stocking them into ponds. The average stocking density is 20,000 per acre and you can expect 500-900 pounds per acre at harvest if everything goes according to the plan. Harvests greater than 1200 pounds per acre have been accomplished in research ponds (0.25 acres) but have never been achieved in commercial size ponds.
Ponds should be designed to completely drain in less than a day. To accomplish this there must be a slope of approximately 4 inches per 100 foot of pond length. There must be one or two drain pipes in the deepest part of the pond depending on the size of the pond. Approximately a 10 inch drain is needed for each acre of water (i.e. a 3 acre pond needs two15 inch drains). However, when the pond reaches approximately 12 inches deep only one 10 inch drain pipe is necessary. This prevents the water from draining completely before providing adequate opportunity for the prawns to follow the water through the drain pipe. A catch basket should be constructed on the outside of the levee to collect any prawns which exit through the drain. This method of harvesting is very efficient if the pond drains at the proper speed with low volumes of water remaining in the pond. Most prawns can be easily collected in a catch basket on the outside of the levee. The remaining prawns will be concentrated in the catch basin in the pond and can be removed with a net or by hand. It is inevitable that some prawns will have to be collected by hand from the bottom of the pond. Keep the bottom of the pond smooth without any holes or depressions which will retain water and prawns as the pond drains. With proper pond design, harvesting can be time and labor efficient. The standpipe should be equipped with a swivel valve, the height of the standpipe will determine the depth of the pond. An anti-seep collar should be used on the drain pipe deep in the levee to prevent seepage of water along the edge of the drain pipe.
Prawns survival at low water temperatures is dependant on how rapidly the temperature changes. The lowest temperature prawns can tolerate and survive is approximately 57F (14C) if the temperature is lowered very slowly over a period of several days, but only 60F (15C) if the temperature change occurs during approximately one day. Therefore, you must remember that smaller ponds will exhibit a more rapid change in temperature than large ponds. Growth of prawns becomes slow at water temperatures below 68F.
