The First Data on Parasites of Monkey Goby Neogobius fluviatilis (Perciformes, Gobiidae) in the Saratov Reservoir

The parasite fauna of the monkey goby Neogobius fluviatilis has been studied from the lower part of the Saratov Reservoir. Six species of parasites are recorded, for one of which (the goby-specific plerocercoid Triaenophorus crassus) the monkey goby is recorded as an additional host for the first time. The 100% invasion of the goby by the alien fluke Nicolla skrjabini makes it possible to attribute it to the main definitive hosts of the parasite in the water body.
