ANDRADE, Rafael Luiz Barboza de; WAGNER, Ricardo Luiz; MAHL, Ilson  and  MARTINS, Ricardo Silveira. Nile tilapia (Oreochromis niloticus) production costs in a farm model of the west region of the State of Paraná, Brazil. Cienc. Rural [online]. 2005, vol.35, n.1, pp.198-203. ISSN 0103-8478.

The objective of this research was to analyze the production cost of fish production in the western region of Paraná, Brazil. The costs were obtained monthly by the GEPEC/Pisciculture group. In general, the costs refer to the commercial exploration of a 24,000m2 area, in eight tanks, which enable the production of 14.4t of Nile Tilapia (Oreochromis niloticus) per production cycle, with an average unit weight of 0.4kg. For the total cost of the implantation, the growth rate was of 0.47% pm (per month) and for the earthwork costs, 0.63% pm, representing around 70% of the initial investments. The fixed costs represented a growth rate of 0.032% pm, the variable cost represented 70.18% of the total production cost and a growth rate of 0.32% pm which demands the necessity of verifying alternatives to decrease these costs, which are very sensitive to the variation of raw material prices. The necessity of the establishment of a responsible agent for the leadership of the food chain was exposed to guarantee its survival.

Keywords : pisciculture; production costs; agricultural economy of Paraná.
