ROTIFERS OF KEPEKTAS DAM LAKE (ELAZIG-TURKEY)*

Abstract

With the aim of identifying the Rotifera fauna of Kepektas Dam Lake, samples were collectedmonthly between January-December 2005. In total 11 rotifer species were identified. As a species-wisepercentage, Kellicttia longispina had the highest level with 57%. When the annual abundance of species wastaken into consideration Polyarthra vulgaris, Colurella uncinata, Asplanchna priodonta and Keratellacochlearis were determined as dominant species. These species were observed in most months of the year and were well observed in their annual abundance. Notholca squamula was classified as cold steno-thermalspecies, as this species was recorded only in February and March. Increases in Rotifer individual numberswere observed in spring and summer months.
