Abstract– Animal and plants associated with water have from times immemorial signified life, fertility and abundance. The fishes, one of the first forms of evolutionarily higher life to appear in water is among the earliest vertebrates. It was therefore regarded as one of the “nighis” of water. The fish community of the Sone is very similar to that of the Alaknanda, although a few lowland species begin to appear, such as Mastacembelus and Channa so that the final species total is a little higher at 54. Again, however, numerically the snow trout and mahseers would tend to dominate the fishery. Fishes are considered as one of the important source of animal protein in all over the world and very popular in all economic classes. The equally in some water will provided embankment population have given most important nutritional food to the people of that were as well as to other parts of river that of the Ganga”. Biological monitoring is a main aspect of today’s water quality assessment of river and lakes. Both abiotic and biotic factors can have profound effects on population size in Sone. Zooplankton biomass and biodiversity were examined in a floodplain system of high hydrological dynamic. Temporal patterns were used to assess the significance of water retention time for the regulation of zooplankton population dynamics. The sampling period covered a board range of hydrological conditions ranging from lotic to lentic situations. Retention time could be identified as the driving variable governing total zooplankton biomass following a sigmoidal relationship. It also proofed to have different effects on rotifers and crustaceans. Rotifer biomass followed a polynomial 2nd order relationship showing a maximum at medium retention time while crustacean biomass was positively linear relation. The present work has presents inter-relationship of fish culture, abiotic and biotic factors of river Sone.
