“…Taxonomic studies with the Cestoda and Monogenea classes were carried out during the first years of study, and address the so-called classic taxonomy, based on the morphological characteristics of the species (Rego & Pavanelli, 1985;Eiras et al, 1986). Over the years, the advance of technology and the modernization of science, allowed studies of integrative taxonomy, which unites morphology and molecular biology, to be carried out, advancing in the molecular characterization of the species, allowing studies of coevolution and specificity in the host parasite relationship (Gasques et al, 2016;Scholz, Takemoto & Kuchta, 2017;Graça et al, 2018;Franceschini et al, 2018).…”

Aim The aim of this study was to present the description of new species of fish parasites in native and non-native hosts and the parasite interaction / host, available in studies for 37 years in the upper Paraná River floodplain. Methods The sampling described in this study is part of a scientometric methodology, in which specific query expressions were used, together with the database available in the Nupelia Sector Library, through Theses and Dissertations. Results A total of 44 species of parasites belonging to different groups were described for 27 species of fish of different orders. In these 37 years of studies, an increase 68% was observed in the number of parasite species, presenting a richness of 201 species in the floodplain, being: Monogenea, Digenea, Nematoda and Cestoda are the groups that present the largest records of species. More than 80 hosts have their parasite fauna registered and most studies are carried out with species of native hosts in the floodplain, being Prochilodus lineatus the host with the highest number of records. Conclusions Parasitological studies are an important scientific tool for understanding the dynamics of ecological interactions in the natural environment, and knowledge of this diversity of organisms is continuous and necessary, and the results of the monitoring carried out in the floodplain during the last 37 years only reinforce this with a constant increase in the description of new species and new records of parasite-host interactions. In times of constant environmental loss and habitat fragmentation, it is of utmost importance to care for and preserve floodplains to maintain biodiversity.
