Currently the biodiversity of marine and freshwater ecosystems have been threatened, especially by environmental problems resulting from the degradation of ecosystems, an example is the stretch of the Middle Tietê River, where the Barra Bonita (SP) focuses almost the entire load of organic waste coming from the metropolitan region of São Paulo, inducing eutrophication with the loss of water quality. This basin is located the Fish River, a tributary of Barra Bonita whose sources are on the slopes of the Cuesta de Botucatu, presenting an altitudinal gradient in a good state of conservation and water quality, with a rich biodiversity of fish associated with the presence of many lagoons. From another perspective, the studies related to parasites and other pathogens of aquatic organisms have considerably increased the relevance, especially those with potential hosts for growing and marketing, given the significant increase in these activities in Brazil and worldwide. Among the agents responsible for diseases in fish are the myxosporean, which can cause significant economic damage, with high mortality ratios. Based on the above assessed in this study the biodiversity of myxosporean parasites of three species of fish, through morphological, due to socio-economic importance of this river to the region and great diversity of fish
