An investigation was conducted for six weeks feeding trial to determine the performance of African catfish （Clarias gariepinus） fingerlings feed diets containing varying replacement level of fish meal with pawpaw seed powder meal （Carica papaya）. Fingerlings of Clarias gariepinus were subjected to five different dietary treatments with varying levels of pawpaw seed powder meal. The diets I-V contained 0, 20%, 40%, 60% and 80% replacement levels, respectively. The experiment was carded out in an 80 litres circular plastic bowls, the treatments were in triplicate. Each bowl contained 12 fingerlings. Feeding was done at 3% body weight per day and fishes were weighed every week. Growth parameters such as specific growth rate （SGR）, weight gained （WG）, food conversion ratio （FCR）, protein efficiency ratio （PER） and mortality were determined. Therefore, it could be concluded that fish meal could be replaced up to 80% with pawpaw seed powder meal in the diet of Clarias gariepinus fingerlings to encourage growth, while at 40% pawpaw seed powder meal inclusion mortality was reduced.展开更多
