Abstract
The aim of the study was to determine the species composition of fish passing the fish pass in the Czchow Reservoir dam in autumn. A total of 2202 individuals representing 13 species were harvested. The fish were dominated by the bleak (93.6%), roach (2.4%), spotted barbel and barbel (1.2% each), and the brown trout (1%). A comparison of the present fish fauna composition with that recorded in the 1950s showed the lack of the nase which used to be a dominant species then, and a dramatic reduction in the contribution of rheophilous species to the ichthyofauna.
