For every two grow-out ponds one extra pond should be maintained as a water reservoir (i.e., a ratio of 2:1 with respect to water holding capacity of ponds ) to stabilize turbid and unstable water sources. If the farmer has only one quarter of the pond should be converted in to a reservoir pond with water depth of at least 2 meters. Water should be stocked in the reservoir pond for at least 14 days before pumping to the shrimp culture ponds to facilitate the growth of plankton in the reservoir. This water can even be used to fill grow-out ponds just one to two days before stocking with seeds. If the water reservoir is not maintained then the grow-out pond should be filled be filled directly with source water at least 14 days before stocking.
