| Description | We studied drift of young-of-the-year (YOY) fish through the turbine of a hydraulic power station on the outlet of the Nové Mlýny water reservoir (Dyje River, Czech Republic, Danube basin). The study was conducted over three years from April to August of 2001–2003. The number of drifting species was relatively small in comparison to species richness in the reservoir. In total of twelve species were caught with drift nets, however only bream, zander and tubenose goby drifted in notable numbers. Fish drifted predominantly at night, and there was no correlation with water temperature or transparency. About ten percent of fish were damaged passing through the turbine, with a high proportion of fish being larger than 30 mm, although up to 30 percent of pikeperch were damaged. |
