Zooplankton community structure of Asartepe Dam Lake was examined by collecting samples in three different seasons (Autumn 2007, Spring and Summer 2008). Rotifera was found the dominant group with 43 species, followed by Cladocera with 3 species and Copepoda with 2 taxa respectively. One of these rotifers, Encentrum felis is a new record for the Turkish fauna. Also some water parameters (pH, dissolved oxygen, electrical conductivity and water temperature) were measured
during field trips.
