The present study was conducted to evaluate the growth performance of Amur common carp under polyculture with Indian major carps (Catla and Rohu) in selected ponds of FRIC, Bhutnal, Vijayapur, Karnataka integrated with and without poultry farm. For this study two ponds were selected. Fingerlings of uniform size were selected and stocked at the rate of 1 No/m2 and the fishes were fed with floating carps feed @ 3% of fish body weight. Among different species stocked, Amur common carp had shown the highest growth (1328.7g and 29.8cm respectively) compared to Catla (1148.9g and 27.9cm respectively) and Rohu (819g and 27.1cm respectively) in pond integrated with poultry farm. Similarly in pond without integrated with poultry farm, Catla had shown the maximum growth (1250. 8g and 29.1cm respectively) Amur common carp followed (1191.69g and 27.4cm respectively) and Rohu (860g and 26.09cm respectively). The specific growth rate of Catla was also highest both the ponds integrated with (2.30) and without (2.27) poultry farm followed by Amur common carp and Rohu. Amur common carp exhibited a better growth compared to other species (Catla and Rohu) in ponds integrated with poultry farm might be due to the omnivorous feeding habit, burrowing nature, spilling off poultry feed and the protein rich droppings from the poultry harbor the desired planktons in the ponds and also consumed directly as a feed. It could be inferred from this study that Amur common carp is most suitable species for polyculture with Catla and Rohu and recommend integrated fish farming in ponds to increase the production and productivity of fish.
