In the search for regional inputs that serve as ingredients of the rations for Amazonian fish, it was decided to use coconut pulp and pituca flour, compared to a commercial ration in the feeding of gamitana juveniles. As objectives, the productive indices of the fish bred in captivity conditions were determined. Determine the protein retention percentages of the rations containing the inputs to be tested. (Coconut and pituca) compared to a commercial ration for fish. A DCA was considered under three treatments and three repetitions. These fish were raised for 90 days in pens lined with anchovy mesh. The 6m3 pens (3mX2mX1m) were located inside an excavated pond, five gamitana juveniles were placed, on average (698 and 32.56cm) fed twice a day with 6% of the biomass of each pen. The physical-chemical parameters of the water were monitored and measured with specific devices. At the end of this first phase, the fish (989.4 and 35.84cm) were used for the protein retention experiment: after three days of fasting, five fish for each ration were fed until satiety, then placed separately in 200L conical incubators, for 24 hours in order to collect the decanted feces. This process was repeated exchanging the fish daily until completing 100g of dry feces for each serving. The bromatological analyzes of the feces were carried out according to the recommendations of the A.O.A.C (1994).
