| Abstract | The dietary protein requirement of Puntius gonionotus fingerlings in a closed recirculating water system was determined. Five isocaloric experimental diets (approximately 450 kcal/100 dry diet) containing protein levels ranging from 15% to 55% in increments of 10% were tested. Fish meal, blood meal and casein were used as the protein sources. The experiment was conducted for a period of 10 weeks and the growth responses of fish fed experimental diets determined in terms of weight gain, specific growth rate (SGR), feed conversion ration (FCR), protein efficiency ration (PER), and apparent protein utilization (NPU), percentage protein deposition, and apparent protein digestibility. On the basis of the growth response, the minimum dietary protein requirement was estimated to be approximately 35.15 %, with a dietary protein to energy ration (P.E.) of 101.05 mg protein per kilocalorie of metabolizable energy. This is similar to that obtained for other herbivorous freshwater fish. Dietary protein levels profoundly affected the carcass composition. Carcass moisture content increased and carcass lipid content decreased with increases in the dietary protein levels, whereas the carcass protein and ash content were relatively unaffected. |
