The purpose of this investigaton was to determinate the effect of different energy levels maintaining constant calorie:protein ratio of 10 kcal digestible energy (DE)/g crude protein (CP), in sábalo cola roja juveniles (Brycon erythropterum). The experiment was performed at the Laboratory of Nutrition and Feeding of Fish and Crustaceans (LINAPC), Academic Department of Nutrition of Universidad Nacional Agraria La Molina. The animals were acclimated and fed with commercial diet during 15 days and after, test diets were administered ad libitum three times a day during 35 days, 72 sábalo cola roja juveniles were used. Fish were obtained from “Amazonic Aquaculture Service” (AAS) fish farm from Iquitos. Data were analized using randomized complete block design, with the standard block size of fishes (small, medium and large), Duncan´s test was used to evaluate differences between means of treatment. The treatments were formulated with differences levels of energy, 2.9, 3.1 and 3.3 Mcal of DE/Kg, respectively with calorie:protein ratio of 10 kcal DE/g PC; the feed was made by least-cost linear programming. Fish were assigned to groups of 8 according to weight and located in tanks. Five periods of seven days each were registered, at the end of each period the feed intake was determined. Weight gain and body size growth was determined at the end of the research. Increased energy mantaining constant calorie:protein ratio did not affect feed intake, weight gain, body size growth, feed conversion, growth rate, protein efficiency rate and feed cost, however, diets with 33% PB and 3.3 Mcal DE/ kg improved productive parameters and feed cost in this stage of fish.
