Abstract

Studies in descriptive taxonomy of fish helminths from the Tiete River are relevant, given the great heterogeneity of hosts described to the site. This study intends analyzing the parasitism Geophagus proximus (Castelnau, 1855) using tools as light microscopy and molecular biology to taxonomic study of helminths found. Geophagus proximus, freshwater fish Perciformes from South America is a little bit studied species, compared to its importance in the food chain of freshwater environments and their commercial importance. The Ibitinga Reservoir is located in the hydrographic basin of the river Tiete - Paraná, and due to the dam of the water resulted in much of its waterlogged margins, making this stretch of the river belonging to the extremely deep Ibitinga municipality and great victim of eutrophication. Therefore, the analysis of the parasitic fauna G. proximus is a great ally to parasitic taxonomy studies. Based on this context, this study provides important data for the global biodiversity of parasites, with great possibilities of description of new species. (AU)
