"The study evaluates fish community in a chronically polluted part of the channelized lowland Elbe River. The effluent from sewage treatment plant exhibited wide set of organic compounds (PAH, PCB, DDT etc.). Fish communities were sampled by boat electro fishing at 12 sites in 4 inter-weir sections in July 2005 and 2006. High fish species richness (24 species) was observed in both seasons. Generalists (bleak, roach, chub) form the majority of the community. There was no significant difference in fish species richness or density among study sections. Significant differences were registered among individual sites. Sites downstream the weirs had significantly higher species richness and density than sites in the middle and upstream weirs. Fish community does not display any indicative remarks concerning water pollution, or sampling strategy was not efficient to recognize it. Channelization and regulation of the study stretch seems to be the most important determinant of fish community." . "Folia zoologica" . "Valov\u00E1, Zdenka" .
