Abstract

ORIG CZ

V originále

The distributions of invasive Neogobius species were investigated in the Slovak section of the River Danube from Bratislava downstream to the village of Chlaba. During October 2004, the main channel of the Danube was sampled, including by-pass, head-race and tail-race canals of the Gabc kovo dam, backwaters and the lower-most sections of the tributaries Maly Dunaj, Hron, Va h and Ipel. Three Neogobius species already documented in Slovakia were captured (monkey goby Neogobius fluviatilis, bighead goby N. kessleri, round goby N. melanostomus), with the latter two species being found in almost all stretches of the Slovak Danube. Monkey goby had a most limited distribution, and no racer goby N. gymnotrachelus were observed. The abundance of particular Neogobius species appeared to depend on the character of the shoreline habitat, and a possible association between larger towns and the abundance of bighead and round gobies requires further investigation.
