Effect of water quality on fish productivity in Talwada pond in district Barwani (M.P.)

Abstract

Physicochemical parameters of water in Talwada pond were investigated with correlation between water quality and fish productivity. Water and fish samples were collected and determined water testing parameters. Outcomes of present study that pond water with average of air temperature 27.5, water temperature 25.5, transparency 22.5, pH 8, alkalinity 135, DO 10.35, BOD 7.7, free CO2 3.12, chloride 13.35, phosphate 1.35, sulphate 83.75 and nitrate 0.58 were observed. The water quality directly affects the fish production in tank. The total fish production during the present study period when combination of three species were cultured, the average annual yield of 1965 kg/hac/year was obtained. The stocking density of 57500 to 45000 fingerlings.
