Abstract
In order to obtain understanding of trematode diversity in the invasive mollusk Viviparus viviparus, the prevalence of larval trematode species (cercariae and metacercariae) in the Tura River near Tyumen, Western Siberia was investigated. A total of 53 snails with a shell height of 17-32 mm were studied. Three species of trematodes were found: cercaria Cercaria nigrospora (3.77 %), cercaria Neoacanthoparyphium echinatoides (5.56 %), metacercaria N. echinatoides (58.5 %, 47-279), non-encysted metacercaria Leucochloridiomorpha constantiae (62.3 %, 2-69).
