Indicadores de eficiência bioeconômica aplicados em unidades de produção familiar de tilápia em sistema semi-intensivo.
The objective of this study was to evaluate the bioeconomic efficiency of pondbased Family Farming Units (UPFs) of tilapia (O. niloticus) in a semi-intensive system in the Ribeira Valley region, São Paulo, Brazil. Eight UPFs were studied and an experiment was developed to define a UFM. The bioeconomic efficiency of the UPFs presented a decrease of 4.58 tons per hectare and an increase of 93 days in slaughtering and commercialization time when compared to that of the UFMs. The return on capital invested can reach up to R$2.76 per kg produced and profitability of 46% in each cycle.
