Avaliação econômica da implantação de um empreendimento de carcinicultura utilizando sistema de bioflocos

Abstract

The aim of this study was to evaluate the economic viability of implementing Litopenaeus vannamei culture in biofloc system in southern Bahia, Brazil. The values for construction, operation and economic indicators were stipulated. The initial investment was R$ 1,623,434.29, the infrastructure was the item that contributed most to this figure, with 73.2%. Effective operational cost was R$ 1,177,658.69 and the items that contributed the most were inputs (46.48%), followed by ICMS (17.76%), Rural Social Insurance (13.62% ), electricity (10%) and hired labor (7.91%). Among the inputs, the biggest cost item was the grow-out feed, with 37.3%. The average EOC and TCP were R$ 16.72/kg and R$ 22.56/kg, respectively. The Net Present Value was greater than zero (R$ 4,142,354.08), indicating that the project has a positive balance over the horizon. The internal rate of return was 47% and the payback period was 2.1 years. Shrimp farming proved to be economically feasible against several simulated scenarios, where the economic indicators obtained were considered satisfactory, except in four situations, which the IRR and payback period values were below those stipulated.
