Interactions of the introduced rotan Perccottus glenii Dybowski, 1877 (Osteichthyes, Odontobutidae) with aboriginal fish species: The parasitological aspect

The parasites of the invasive Chinese sleeperPerccottus glenii(Fam. Odontobutidae), with the first report ofNippotaenia mogurndaein Ukraine

“…but the larvae live in Anuran amphibians (Biserkov and Kostadinova, 1997). This tapeworm has already been reported from the Chinese sleeper in the European part of Russia, where it infects from 3.6% to 37.5% of fish (Sokolov et al, 2011b. The nematode Spiroxys contortus is a parasite from the European pond terrapin [Emys orbicularis (L., 1758)] but the paratenic hosts are different small-sized fish, insect larvae, tadpoles and adult frogs (Hedrick, 1935;Moravec, 1994).…”

“…The nematode Spiroxys contortus is a parasite from the European pond terrapin [Emys orbicularis (L., 1758)] but the paratenic hosts are different small-sized fish, insect larvae, tadpoles and adult frogs (Hedrick, 1935;Moravec, 1994). It is considered a common parasite of the invasive Chinese sleeper in Russian waters, infecting up to 100% of fish (Sokolov et al, 2011b. The invasive Chinese sleeper functions as a paratenic host in the life cycle of the parasites of indigenous reptiles in Europe.…”

“…For example, 12 species were found in the Neverovski Karyer Reservoir, 13 species in Lake Krugloe (both in the Volga basin), 16 species in Lake Glushitsa Podstepnaya (Don River basin), and 18 species in the Włocławek Reservoir on the Vistula River (Sokolov et al, 2011a(Sokolov et al, , 2011bMierzejewska et al, 2012). The sizes of fish were not larger than in our study: TL = 7.4−21.0 cm in the Neverovski Karyer Reservoir, TL = 4.9-22.8 cm in Lake Krugloe, TL = 5.0-19.5 cm in Lake Glushitsa Podstepnaya, and TL = 4.1-14.4 cm in the Włocławek Reservoir (Sokolov et al, 2011a(Sokolov et al, , 2011bMierzejewska et al, 2012). In all cases the authors did not present data on the average values and standard deviation.…”

“…The parasites of the invasive Chinese sleeper have been thoroughly studied in the European part of Russia Sokolov et al, 2011aSokolov et al, , 2011b as well as in Poland (Mierzejewska et al, 2010;2012), including collections from Serbian (Nikolic et al 2007) and Slovakian waters (Košuthová et al, 2004(Košuthová et al, , 2008(Košuthová et al, , 2009Oros and Hanzelová, 2009). In Ukraine, the first study of the Chinese sleeper parasites was carried out by Maslovsky et al (2011), who reported Trichodina sp.…”

Trichodinids (Ciliophora, Peritrichia) Of Perccottus Glenii (Actinopterygii, Odontobutidae) In Three Ukrainian Rivers

“…Th e data on the trichodinids infecting invasive Chinese sleeper in Eastern Asia are presented in Sokolov et al (2011Sokolov et al ( a, b, 2012, who registered six taxa of these ciliates: Trichodina sp. ; Trichodina acuta Lom, 1961;Trichodina nigra Lom, 1961;Trichodina pediculus Ehrenberg, 1838, and Trichodina mutabilis Kazubski et Migala, 1968.…”
