First Data on Parasites of Neogobius iljini (Perciformes, Gobiidae) of the Middle Volga

摘要

The results of a study of the fauna of multicellular parasites of the Caspian bighead goby Neogobius iljini (Vasiljeva et Vasiljev, 1996) in three reaches of the Kuibyshev Reservoir (Middle Volga) are presented. Twelve species and undefined forms of parasites were found, including a specific to the fam. Gobiidae metacercaria Holostephanus cobitidis. The most diverse fauna of macroparasites is observed in the lower reaches of the reservoir (Priplotinny reach). The dominant species in the parasite fauna of the Caspian goby of the studied reservoir is the alien trematode Nicolla skrjabini, whose natural range is limited to the rivers of the Azov and Black seas basin.
