The results of a study of the parasitofauna of Cyprinus carpio in the Krynka River basin, which indicate a significant prevalence of monogeneidosis, are presented. The object of the study is 26 specimens of carp subjected to a complete parasitological autopsy. The species diversity of parasites was revealed: arthropods (Lernaea cyprinacea, Ergasilus sieboldi) and flatworms (Dactylogyrus extensus, Diplozoon paradoxum, Caryophyllaeus fimbriceps). Dactylogyrus extensus is the dominant species (EI 73.1%), Diplozoon paradoxum and Ergasilus sieboldi are also significant. The discovered parasites, having adapted to Cyprinus saglio, use different strategies of defeat – from gills to intestines.
