| Abstract | ||||
| This work was carried out to study the effects of various dietary protein and oil levels on growth performance, survival rate and feed and nutrients utilization of rabbitfish, Siganus rivulatus, fly. Nine experimental diets were formulated to contain 25, 30 and 35 % dietary protein and with each protein level, cod liver oil were added at rates of 0.0, 3.0 and 6 % on dry weight of the diet. Each diet was given to twenty fish (about 0.58 g each) in two glass - aquaria at descending rates of 10, 7 and 5% from live body weight. The results of this study showed that diet containing 35 % crude protein and 6.0 % cod liver oil was the best food for higher growth performance, survival rate and feed and nutrients utilization, and also indicated the possibility of reducing protein level by adding cod liver oil up to 6 % of the diet. | ||||
