Examination of 102 snails of Viviparus contectus from Rybinsk Reservoir in July–August 2023 revealed the presence of trematodes metacercariae of three families: Echinostomatidae, Cyathocotylidae and Leucochloridiomorphidae. Neoacanthoparyphium echinatoides was the species with the highest prevalence and intensity of infection (98.5%, 41.7, 1–192), followed by the Linstowiella viviparae (86%, 17.2, 3–45). Unencysted metacercariae Leucochloridiomorpha constantiae had a low prevalence and intensity
