During 2018, biomonitoring of the Luda Yana River ecosystem was carried out by examining the biological elements of quality: the freshwater fish species common roach (Rutilus rutilus (Linnaeus, 1753)) and its endohelmiths and endohelminth communities as bioindicators. 45 specimens of common roach are examined for parasites and three species of endohelmiths (Caryophyllaeides fennica (Schneider, 1902) Nybelin, 1922; Acanthocephalus lucii (Mueller, 1776); Rhabdochona denudatа (Dujardin, 1845) Raillet, 1916) are fixed. New host and locality records are reported. The analysis of the dominant structure of the established intestinal parasite complex was presented to the level of the component community. For an ecological estimation of the freshwater ecosystem, principal biotic indexes are fixed. The bioindicator significance of the identified parasitе populations and communities are discussed.
