【 摘 要 】

In this work, the impact of fish farming activitieson the Queixada, Macuco and Pari-Veado Rivers in the Paranapanema watershedwas evaluated. Physical, chemical and microbiological parameters were quantifiedin these aquatic systems followed by application of multivariate statisticalanalysis (MSA) and water quality index (WQI) tools. Watersheds where fish farmingactivities are predominant presented WQI > 52 indicating goodquality, whereas MSA demonstrated bad quality for these aquatic bodies. Theresults showed that the degradation in this watershed follows the fish farmingactivity. The MSA index is more restricted than the "National Foundation Sanitation"(NFS) index routinely used to infer water quality.
