During summer 2019, 15 specimens of round-scaled barbell (Barbus cyclolepis Heckel, 1837) and 12 specimens of Orpheus dace (Squalius orpheus Kottelat & Economidis, 2006) from Topolnitsa River were collected and examined with standard techniques for parasites. Helminth parasites were recorded in 9round-scaled barbell specimens (60%) and 7 Orpheus dace specimens (58.33%) from Topolnitsa River. Only one parasite species was identified in both cyprinid fishes –the acanthocephalan species Pomphorhynchus laevis (Zoega in Müller, 1776). Bioindicator significance of established parasite species was discussed for ecological evaluation of the state of the studied freshwater ecosystem. New data for the helminths of round-scaled barbell and Orpheus dace from Topolnitsa River are presented.
