The objective ofthis study was to evaluate the influence of two levels of digestible energy(3250 and 3500 kcal kg-1) in conjunction with three levels of crudeprotein (25, 30 and 35%) on the productive performance of catfish (Rhamdiavoulezi) juveniles. Two-hundred and forty catfish juveniles with 95.55±6.70g average weight and 20.43±1.13 cm total length were randomly assignedinto twenty-four 370 L-cages, in a factorial arrangement with six treatmentsand four reptitions. Feeding was performed four times a day, ad libitum.At end of experimental period, the factorial analysis of variance showed significantinfluence with respect to the different parameters evaluated. The fish fed withdiets of 30% crude protein and 3,250 kcal digestible energy kg-1of diet presented the best results. Therefore, diets with at least 30% crudeprotein and 3,250 kcal digestible energy kg-1 are recommend for catfishjuveniles.
