Warm water prawn is farmed in ponds in many parts of the world. These ponds are open air and typically found nearby to a coastal water body, used as the water source. Some ponds may be lined to prevent erosion, though a sandy bottom is recommended so that the prawns may burrow. Aeration is important, and many ponds exhibit a fountain or paddle wheel for this purpose. Warm water prawn are sensitive to high ammonia levels, which can be reduced by avoiding overstocking and overfeeding. High water temperatures, which can create algal blooms, and low salinity are also a threat to the prawn.
