Abstract: Conventional multispecies polyculture with compatible native species intercrop augments optimum utilization of the ecological niches in the pond ecosystem, diversity conservation, food value, and poverty alleviation potential through the direct involvement of rural people. Given the conservational value and the aquaculture potential of several indigenous species, Gardi Bangana dero and Sahar Tor putitora have been identified as important food fish. Rohu Labeo rohita and Naini Cirrhinus mrigala are two other native fishes that fetch a very high market price and are of high cultural value. A polyculture experiment was carried out on the Rohu, Naini, Gardi, and Sahar with the objectives to evaluate the optimum stocking density in terms of average body weight, specific growth rate, and total fish production of these fishes for nine months. Results showed that the final body weight of Rohu, Naini, Gardi were high in respective major polyculture systems, but Sahar was high in Naini major polyculture system. Also, net fish yield of Rohu was observed significantly higher in Rohu major polyculture system than in Naini major and Gardi major polyculture systems but not with control polyculture systems. Whereas, parameters of Naini, Gardi and Sahar observed similar in all polyculture systems. Apparent Feed Conversion Ratio was found higher in Gardi major polyculture system than others. In case of survival, all fish species had high survival rate in Naini major polyculture system. Thus, the Naini major polyculture system is concluded to be the optimum combination for these particular species.
