The parasites of the invasive Chinese sleeper Perccottus glenii (Fam. Odontobutidae), with the first report of Nippotaenia mogurndae in Ukraine

Abstract

The parasites of the Asian invasive fish, Chinese sleeper Perccottus glenii, were studied in 6 localities in different parts of Ukraine. In total, 15 taxa of parasites were registered; among them were 1 species of Microsporidia, 5 species of ciliates, 2 species of cestodes, 2 species of trematodes, 2 species of nematodes, 1 species of acanthocephalan, 1 species of parasitic crustacean and 1 mollusk (glochidia). The invasive Chinese sleeper is included as a paratenic host in the life cycle of the parasites of indigenous reptiles in Europe. The non-indigenous cestode Nippotaenia mogurndae occurred in the intestine of the Chinese sleeper from the Ivachiv Reservoir (Dniester River basin). This cestode is recorded for Ukrainian fauna for the first time. In addition, 3 species of parasites were recorded in the Chinese sleeper for the first time: Nicolla skrjabini, Cosmocephalus obvelatus and Pomphorhynchus laevis. We note the low similarity among the different localities and the low parasite richness, that suggest that the parasite fauna of the Chinese sleeper in Ukraine is in transition.
