The aim of the present study was to evaluate three experimental diets, containing 45, 50 and 55 percent of crude protein, isocalorics (3488 Kcal EM/Kg), isolipidics (15 percent of total lipid), isophosphorics (2 percent of total P) and isocalcics (3 percent of total C), and a commercial diet Nicovita Classic Cobia 20 (57.41 percent of protein) in juvenile chita Anisotremus scapularis, for 8 weeks by increasing weight, size and biomass, feed consumption, feed conversion, specific growth rate and feed cost. The experiment was carried out at the Laboratory of the sub project PNIPA with code PNIPA-ACU-SIADE-PP000070, located in Av. Miguel Grau #262, district of La Punta, Constitutional province of Callao, where was implemented an aquaculture recirculation system (RAS), with 12 aquariums (experimental units) for the growth tests. The “feed was manufactured in the facilities of the Balanced Feed Plant of the National Agrarian University La Molina. There were used 72 juveniles of 19.95 g of liveweight and 10.31 cm of total length, randomly distributed in recirculation system aquariums, with three repetitions per treatment. The data obtained was analyzed using a completely randomized design (DCA) and using the Tukey test to evaluate statistically significant differences between diets. The chitas fed with diets of 55 percent of crude protein had highly statistical differences in relation to those fed with diets of 45 percent of crude protein, presenting the first greater weight gain, increasing biomass and feed consumption. Also, the chitas fed with diets of 55 percent of crude protein had greater weight gain, increasing biomass, final size, feed conversion and economic reward in comparison of the ones fed with diets of 50 percent of crude protein. Therefore, based on numerical and statistical analysis, the inclusion of 55 percent of crude protein in the diet obtained the best productive yields in the evaluated parameters for juvenile chita Anisotremus scapularis, except for food consumption, where the inclusion of 45 percent of crude protein in the diet obtained the lower value.
