This study presents the current state of research of freshwater fishes' parasites in Brazil, exploring the watersheds requiring further studies. The articles used were obtained through searching the databases ISI and SciELO, as well as direct search in the Curricula Vitae of researchers in this area. The survey was conducted during the month of March 2012 and 685 articles were obtained. The most studied group was Monogenea. Taxonomy was the most common studied subject. The most reported river basin is the Amazon region and the region of Parana. The largest concentration of periodic articles was Memorias do Instituto Oswaldo Cruz. Most articles were published in journals with Qualis B1 and B2 and without impact factor. More than half of the articles were found in the Curriculum of researchers. It is believed that this information will contribute to the knowledge of the available literatur...

An ichthyoparasitological study on 166 fishes, belonging to Poecilia reticulata Peters, 1859 (Poeciliidae), Rhamdia quelen (Quoy & Gaimard, 1824) (Pimelodidae) and Hypostomus ancistroides (Ihering, 1911) (Loricariidae) in tributary streams of the Pirapó River, located in and around urban city of Maringá, Paraná State, Brazil. The research aimed to recognize the endoparasite community of fishes analyzed, as well as to improve the knowledge about host/parasite relationships. We analyzed the correlation between the total length of the fish with levels of parasitism (prevalence, abundance). Due to the existence of sexual dimorphism in the species P. reticulata, we investigated the possible influence of sex of this fish on parasitism. In addition, we also analyzed the body surface and nostril for ectoparasites studies. There were no metazoan parasites on the body surface and nostril of...
