<br/><br/> Effect of seven artificial diets, having protein contents ranging from 10 to 48%, on the growth and food conversion in young Tilapia nilotica of mean weight 24 mg were tested in 0%o, 5%o, 10%o, and 15%o salinities. Growth of young T. nilotica was consistently better on diets containing 28-30% protein. For diets up to 30% protein, the fish grew best at 10%o, and for diets of higher protein contents, fish grew best in fresh water. Efficiency of food conversion increased/vith dietary protein content up to 30% protein level and then decreased at higher contents. Food conversion efficiency was greater for young fish raised in 10%o than in other salinities.<br/>
