The colonization and occupation of Paulista West lands promoted different kinds of impacted actions in aquatic and terrestrial environment, as well as deforestation, pollution, rivers silted up and adjacent areas that lead to severe disappearance of many native species from fauna and flora. Nowadays, the studies and recovering programs of environment in damaged aquatics ambients by men's actions are of great social-ecological importance. Therefore, the objective of this work was to evaluate the occurrence and fishes’ species composition from Paraguaçu Paulista municipal touristic balneary (SP) and give subsidies to support the sporting fisheries. The fishes´ collects were realized in Agost/02 (dry period) and March/03 (rainy period) in 3 sites from the reservoir, using seining-net and gill net. The fishes collected were quantified and identified by site of origin, in native or exotic species. The results showed an occurrence of 4 orders, 9 families, 11 genera and 12 species of fishes. The saguiru-do-rabo-amarelo and the lambari-do-rabo-amarelo were the most abundant species in number and biomass. The presence of the exotic tilapia-do-nilo was also verified in this balneary. Mild measures were indicated related to fisheries sustainable management for this ecosystem, defining the use of the land and the occupation roundness.
