4.1 Buildings and equipment facilities

In tropical freshwater prawn hatcheries, special facilities for holding broodstock do not normally exist. However, they are necessary in areas of seasonal grow-out, where over-wintering of broodstock is essential. This is because you need to start the larval rearing cycle early, so that grow-out facilities can be stocked as soon as the climatic conditions are favourable. Broodstock facilities and management have already been discussed. The size of specific items of equipment depends on the number of postlarvae (PL) to be produced by each hatchery.
