Species diversity of fishes in relation to physicochemical status of the Yamuna at Kalpi (UP) India

Fishes are the primary indicators of pollution of water bodies because they are conspicuous and changes in physicochemical characteristics of water affects their growth and reproductive multiplication rate. The study reveals the species diversity of fishes in relation to physicochemical status of the Yamuna river at Kalpi stretch. Four sampling station were selected on the Yamuna river for sample collection to analysis species diversity of fishes in relation to physicochemical status of studied river. Sampling for fish fauna and physicochemical analysis of water was done simultaneously for one year. The collected samples were analysed for selected physicochemical parameters and collected fishes was identified in the same time. Selected physicochemical parameters were Water Temperature (W.T.), pH, Conductivity, Turbidity, Total Dissolved Solids (T.D.S.), Total Hardness (TH), Total Alkalinity (T.A.), Chloride (Cl), Sulphate (SO4), Phosphate (PO4), Nitrate (NO3), Dissolved Oxygen (D.O.), Biochemical Oxygen Demand (B.O.D.) and Chemical Oxygen Demand (C.O.D.). Mostly physicochemical parameters were found suitable for survival and growth of fish fauna. Yamuna river at Kalpi stretch have high potential for fish production which is not utilize till now
