Abstract

Six isonitrogenous diets (30% protein) were prepared, D0, DIO, D20, D30, D40 and D50. Diet Do the control diet) consist of fishmeal as the protein source. Diets D10 to D50 had fish meal replaced systematically with yeast single cell protein (SCP) in the order 10, 20, 30, 40 and 50%, respectively. Trial feeding was carried out with these feeds on Oreochromis niloticus. The cost benefit evaluation of these diets was carried out. Result showed that the 50% yeast SCP substituted diet had the lowest profit index, the, least expenditure as well as the best sales, net profit and cost-benefit ratio.
