Parasites of young pike Esox lucius Linnaeus, 1758 in the Saratov reservoir

The fauna of multicellular parasites of pike fingerlings in the conditions of a floodplain reservoir (the middle section of the Saratov reservoir) was studied. 2 broadly specific species of trematodes were found that infest fish by topical and trophic means. The dominant species in the juvenile pike parasite fauna is metacercariae Paracoenogonimus ovatus , the sexually mature form of which is potentially dangerous to humans.
