Abstract

This project aims to study the longitudinal variation of the fish community and biological integrity of a small impacted river of Piracicaba Basin, in order to assess the utility of the fish fauna as a biomonitoring tool for small tropical rivers. The structure of the ictiofauna will be studied at different points in the dry and rainy seasons, using electrofishing and assessing biomass, abundance, diversity, dominance and richness of species. For the study of biological integrity, the condition factor, hepatosomatic index, Index of Well-Being (IWB) and Index of Biotic Integrity will be used (IBI). For the calculation of the IBI, data will be compared to reference sites either from literature or from a less impacted river from the same region. Results will be compared to physical and chemical water analyses obtained from the different sites. From the integrated analysis of the data, informations about the best tools for an appropriate management of rivers in similar conditions will be generated. (AU)
