During 2018, 22 specimens of the round-scale barbell from the Tamrashka River (Bulgaria) were examined for helminths. B. cyclolepis is an endemic fish species of the Maritsa River Water Collection. Five parasite species (Allocreadium isoporum Ergens & Lom, 1970; Caryophyllaeides fennica (Schneider, 1902) Nybelin, 1922; Pomphorhynchus laevis (Müller, 1776); Rhabdochona hellichi (Šramek, 1901) Chitwood, 1933; Rhabdochona gnedini Skrjabin, 1948) belonging to four classes and four families were fixed. The Tamrashka River is a new habitat for All. isoporum, C. fennica, P. laevis, Rh. hellichi and Rh. gnedini of B. cyclolepis in Bulgaria. The dominant structure of the parasite communities was discussed based on the level of the component community. The bioindicator role of the studied parasite populations and communities are presented.
