The purpose of this study was to determine the best protein:carbohydrate ratio in this hybrid's diet. A water recirculation closed system was used, composed of twelve tanks with 500L each. 144 juveniles (12/tank) with initial weight of 12.63±2.52g and total length of 12.34±2.06cm were distributed. The experiment lasted for 50 days and the fingerlings were feed four diets containing different protein:carbohydrate ratios (1.24; 0.84; 0.56 and 0.33). The protein:carbohydrate ratio influenced performance. The 0.84 ratio promoted better weight gain, smaller apparent feed conversion, great feed intake and largest daily specific growth rate. In short, the 0.84 protein:carbohydrate ratio is most indicated for this hybrid. The results demonstrated metabolic mobilization of nutrients for maintenance of glucose and growth. The 0.84 protein: carbohydrate ratio was recommended for the hybrid.
