This research has been carried out to study on the effect of different levels of protein (45, 50, 55 and 60%) and energy (20, 22 and 24 KJ/g) on growth performances, survival rate, nutrition factors and chemical composition of juvenile fish of silver sea bream (Sparidentex hasta) wheighing 27 grams.The experiment was done with 12 treatments and 3 replicate for each treatment. The rearing period was 56 days in 300 liter polyethylene tanks (with 200 liter water volume and with water exchange of 1 liter/min). In each tank eighteen fish were stocked. Biometry was done in every two weeks. At the end of experiment one fish was used for chemical analysis of body. Finally, with consider to obtain results from Two-way ANOVA, the 50% of protein level and 22 KJ/g of energy level is suitable for making nutrition for this species.
