Special attention was paid to the quality of population of lake minnow Eupallasella percnurus. By the time the extensive drainage works were done in the 60s and 70s of the 20th century, Polesie Lubelskie was rich in small water reservoirs. As a result of drainage of wetlands, many of them disappeared. Among those which still exist, most of them are located in the Tyśmienica valley. The study revealed that the studied reservoir inhabited seven fish species representing two families. It was also found that structure of dominance and biomass structure is very diverse. In each reservoir the dominant species was different. The lake minnow E. percnurus was determined in three reservoires.}, type={Artykuły / Articles}, title={Analysis of changes of structure of ichthyofauna in the post excavation reserviors (example from Polesie Lubelskie)}, URL={http://www.journals.pan.pl/Content/107207/PDF-MASTER/3%20Kolejko.pdf}, keywords={ichthyofauna, small water reservoir, Polesie Lubelskie (Poland)}, }
