SILVA, J.R. et al. Economic return from cage production of Pacu in itaipu reservoir, Brazil. Arch. zootec. [online]. 2012, vol.61, n.234, pp.245-254. ISSN 1885-4494.  https://dx.doi.org/10.4321/S0004-05922012000200009.

The aim of this study was to evaluate the economic profitability a project of aquiculture in cage for the cultivation of pacu (Piaractus mesopotamicus) with an initial medium weight of 1 kg. The study was done to provide information for decision making investors, farmers, technicians, foment organs and other institutions related to the area. To evaluate the economic profitability scenery, a deterministic method, with the help of an electronic spread sheet, was used. It could be verified that the economic outcome indexes in pacu breeding in 160 cages in the Itaipu reservoir, presented the worst results in scenery I with a profitability index of -17.22%, due to diet conversion of 3.58 and the ration price (R$ 0.75 kg). The analysis of return on investment (ROI) presented indexes of 1.30, 1.36, 1.47 and 1.54 R$/kg between A and D sceneries, respectively. The medium financial equilibrium point between the projections was of R$ 226921.12 and the average of minimum value to be produced was of 55 286.7 kg pacu, based on the physical equilibrium point of the project with one hundred and sixty net ponds. For a better economic return it is necessary to breed at least 40 946.4 kg pacu in one hundred and sixty net ponds with a diet conversion of 1:2.49 and the fish selling price of 4.00, reaching a profitability of 31.78% on the gross revenue with a ROI of 1.54 R$/kg produced.
