The Parasite Fauna of the Round Goby Neogobius melanostomus (Perciformes, Gobiidae) in the Kuybyshev Reservoir (Middle Volga)

Abstract

The fauna of multicellular parasites of the round goby Neogobius melanostomus (Pallas, 1814) was studied in three reaches of the Kuybyshev Reservoir. Ten species and forms of parasites unidentified to species level were found, including metacercariae Holostephanus cobitidis and Apatemon gracilis that are specific to the family Gobiidae. The alien trematode Nicolla skrjabini is the dominant species in the parasite fauna of the round goby in the studied reservoir; its native range is restricted to the rivers of the Sea of Azov and Black Sea basin.
