This work had as aims to analyze the occurrence of parasites in freshwater fish at the artificial lakes in the hydrographical basin of the Quinoá narrow channel, Acre. In the period of January to July of 2013 eighty-eight specimens of freshwater fish of two lakes of the Quinoá narrow channel were analyzed, being thirty-one from Pyrrhulina sp, nine Apistogramma sp, six Australoheros sp, five Acestrorhynchus falcatus, twenty Leporinus sp, nine Hoplias malabaricus and eight Ctenobrycon hauxwellianus. The fishes were submitted to the investigation of parasites that had beginning with the ectoscopy and the necropsy. The gills, eyeball, abdominal cavity and fins were inspected. The gills and eyeball of each captured fish were withdrawed, conditioned in containers of glasses containing formaldehyde 4% for subsequent analysis. The collected ichthyoparasites, fastened in alcohol to 70%, they were put in temporary histological sheets for analysis and visualized under optical stereoscopic microscopy. From seven species of fish studied, three presented parasites. The analyses demonstrated parasitic infestation in H. malabaricus, for Eustrongylides sp, and Contracaecum sp; A. falcatus, for Eustrongylides sp, and Leporinus sp, for Monogeneans species, during the dry period, the months of June and July. It was also observed, to be this the first registration of Eustrongylides sp in A. falcatus.
