WebAug 1, 2010 · Both tilapia and carp stir pond sediment in search of food organisms, and tilapia sweep out large holes in pond bottoms to make nests. These actions possibly incorporate recently-deposited organic matter into sediment to minimize its loss during pond draining for harvest. WebThe productivity of ponds depends largely on the nature and properties of the bottom soil. Hillary et al. (1962) observed that the algal production was associated with nutrients status of the pond soil in some aquaculture ponds. Boyd (1973) found a close relationship between the base saturation of bottom mud and total hardness of the water.
