Fish parasites represent a major part of aquatic biodiversity. The aim of present investigation was to assess the diversity and distribution of parasites from some fish species from the Prut River. Fish were sampled from three station on Prut River (Rădăuți, Drânceni, Oancea) during the year 2020. The different types of fishes from 5 families Cyprinidae, Esocidae, Percidae, Siluridae, Cobitidae have been examined for analysis of the distribution of parasites from these fish, in order to complete the existing data on metazoan parasites of freshwater fishes in the Romanian sector of Prut River. Parasitological investigations were performed on fresh samples by classic methods and the obtained results were expressed in grades of prevalence and intensity. In the analysed fish, were identified 12 parasitic species belonging to 6 systematic groups: Protozoa, Monogenea, Trematoda, Cestoda, Nematoda, Anelida. The prevalence of the parasitosis varied among examined fish species. The ciliated protozoa and monogenic worms were the most commonly identified parasites, but the intensity of parasitism was low. The effects of parasites on fish hosts in the natural environment may be difficult to isolate and quantify.
