As silt accumulates,\nthe overall capacity of a pond decreases. Fish ponds which were not desilted\nfor years, ponds had become shallow, which may aggravate weed growth. <\/p>\n\n\n\n

Silt can lead to pond turbidity which interferes with\nthe sunlight penetration and hence limits the phytoplankton production which is\nthe base of the food chain and ultimately affects fish production.<\/p>\n\n\n\n

In spawning ponds, silt\nand mud can cover fish eggs and can also hide the fish feed \u2013in case of sinking\nfeed- and make it inaccessible to pond fish.\n\nDe-silting of earthen ponds is a typical and periodic operation carried\nout from time to time. In small ponds as shown in the inserted picture, the\nde-silting is done manually while machinery such as dredgers, excavators, sludge pumps and agitators may\nbe used in larger operations and lakes.\n\n\n\n<\/p>\n","protected":false},"excerpt":{"rendered":"
