The study presents for the first time the Cherna River, southern Bulgaria, Aegean water basin, the results of research on the biological diversity and helminth communities of the Round-scaled barbell Barbus cyclolepis Heckel, 1837. 30 specimens of B. cyclolepis are studied. Infection by 5 species of helminths are found (Allocreadium isoporum (Loos, 1894); Bathybothrium rectangulum (Bloch, 1782); Caryophyllaeus laticeps (Pallas, 1781); Capillaria petruschewskii Zeder, 1800; Neoechinorhynchus rutili (Müller, 1780)). The infection indices and the dominant structure of helminth communities are presented. Basic biotic indices are determined. Helminth communities are analyzed at two levels: infracommunity and component community. All established parasite species are autogenous for the helminth communities of the Round-scaled barbell from the freshwater ecosystem of the Cherna River. New data for helminths and helminth communities of B. cyclolepis are presented. The bioindicator significance of helminths and helminth communities are discussed.
