Fish fauna of the Oster River basin (Desna River basin, Ukraine) – recent data

Abstract

According to recent data, fish fauna of the Oster River basin numbers 21 species, including two introduced species: Perccottus glenii and Pseudorasbora parva. 17 species of fish were registered in the lower section of the river (4 of them for the first time), 21 species were found in the middle section (12 of them were not previously noted for this section) and only 11 species were found in the upper section (6 species were not previously noted for this section). Six species-Pseudorasbora parva, Misgurnus fos silis, Pungitius platygaster, Gymnocephalus cernua, Babka gymnotrachelus and Protero rhinus semilunaris-are recordered in the Oster River for the first time. Fish population of the lower part differs by qualitative composition, primarily due to its link with the Desna River. Only 11 species were registered in three tributaries of the Oster River and in their basins. Nosivochka River has 6 species, including introduced Cyprinus carpio and Hypophthalmichthys molitrix. Five species were recorded in the Divytsia River basin and six species are found in the V'iunnytsia River. The most frequently caught species in the Oster River basin were Leucaspius delineatus and Rhodeus amarus (F = 75.0), Scardinius erythrophthalmus and Tinca tinca (F = 66.7).

The Chinese sleeper (Perccottus gleniiDybowski, 1877) in Ukraine: New data on distribution

“…Since then, the species has spread into the River Ros itself and further tributaries, as well as the rivers Rosava and Rostavytsya. Later findings include those in the River Desna basin (Merzlikin & Fedorov, ; Roman, , , ; our data), in ponds of the River Sula basin within the Sumy region (Merzlikin & Fedorov, ) and in the rivers Trubizh, Irpin, Teteriv, Zdvyzh and Vilshanka (own data). All of these rivers feed fish ponds where farming of silver carp ( Hypophthalmichthys molitrix ), bighead carp ( Hypophthalmichthys nobilis ), grass carp ( Ctenopharyngodon idella ) and Prussian carp ( Carassius gibelio ) takes place.…”

The species has also been recorded at 10 sites in the Vistula basin (above reports and Lesnik & Dykyi, 2013;Zabytivsky & Lesnik, 2008); 30 sites in the Dniester basin (National Museum of Natural History collections; own collections -2 sites (Fedonyuk, 2005;Hoch & Kvasha, 2003;Khudyi, 2002;Moshu & Guzun, 2002); 40 sites in the Danube basin (own data -6 sites; National Museum of Natural History collections; Didenko et al, 2010;Kozub & Sivohop, 2000;Kosco et al, 2004;Kurtyak, Talabishko, Stegun, & Velikopolskiy, 2009;Lietytska, Afanasyev, Guleikova, & Golub, 2015;Movchan, 2000;Sivohop, 1998); and five sites in the Southern Bug basin (three from own data [see one of them also in: Kutsokon et al, 2014], and two from museum collections).…”
