HYDROCHEMICAL PARAMETERS AND BIOMETRIC DATA OF FISH SPECIES FROM THE BORORÉ, BILLINGS RESERVOIR, SÃO PAULO, BRAZIL

The artisanal fishing is an important activity in Billings Reservoir (São Paulo, Brazil) and there is a paucity of biometric data about the fish in this region. Thereby, it is important to provide data about ichthyofauna that can be used for future management actions. The aim of this study was to present some data about the water quality and biometric data on fish species collected at the Bororé site (Billings Reservoir). In general, the obtained hydrochemical data raised a concern about the water quality because some parameters were above the established limit for body water class 2. A total of 170 fish were captured, corresponding to seven species and one genus. Geophagus brasiliensis was the most representative species (36%), followed by Astyanax bimaculatus (25%) and A. eigenmanniorum (20%). The hepatosomatic index (HSI) data showed differences in energy displacement between the species; the highest HSI values were observed in Hoplias malabaricus (HSImale = 1.33 ± 0.20; HSIfemale = 1.17 ± 0.82) while the smallest HSI was observed in A. fasciatus (HSImale = 0.47 ± 0.14; HSIfemale = 0.68 ± 0.35).
