Since the beginnings of humanity the wáter bodies offers several benefits to society. However, the population increase and acceleration of the economy, and the consequent increase in demand of industry and agriculture, increased the multiple uses of water, resulting in impacts of various kinds, which require different types of qualitative and quantitative assessment and also long-term continuous monitoring. In this context, the concerns and the need to safeguard water resources should be consolidated in Brazilian society, and increasingly refined tools to assess the quality of the systems are constantly being developed. Parasites of fish are components of aquatic ecosystems highly sensitive to the anthropogenic environmental actions (construction of reservoirs, introduced species, pollution, installation of cages, forestry, etc.), which alter the composition and structure of parasite communities. Thus, these organisms can be used as indicators in environmental studies and conservation of aquatic ecosystems. In this sense the objective of this project will be: 1) characterize the component helminth parasite communities of six species of fish (Hoplosternum lilttorale, Iheringichthys labrosus, Prochilodus lineatus, Leporinus friderici, Rhamdia quellen and Pimelodella sp.) of the Jurumirim Reservoir, Upper Paranapanema River, SP, Brazil; 2) Assess the possible variations in the composition of helminth fauna of the hosts above in relation to the longitudinal gradient (lotic, transition and lentic) and cross the dam (main tributaries: Taquari river , Paranapanema iver and Veados river) and 3) Check the potential bioindicator of helminth parasites of fish from Jurumirim Reservoir, mainly on the issue of water quality and trophic state of the environment.
