Diversity and Abundance of Rotifera in Kad？k？y Reservoir of Turkey

This research has been carried out to determine diversity and abundance of Rotifera in Kad？k？y Reservoir. For this purpose, Rotifera and water samples were collected monthly from March 2010 to February 2011 at three different stations in the reservoir. A total of 33 species from Rotifera were determined in the qualitative evaluation of samples taken from the reservoir. The quantitative evaluation of the Rotifera samples revealed presence of an average of 70 472 ind m-3 in Kad？k？y Reservoir. The maximum number of Rotifera were recorded at 1st station (81 819 ind m-3); in May (100 901 ind m-3) and in spring season (83 458 ind m-3). Asplanchna priodonta, Brachionus angularis, Filinia terminalis and Keratella cochlearis sampling in all months were found to be the most common species during the study. When we evaluate the species identified in the reservoir, the distribution of the individuals that make up the Rotifera fauna and physical-chemical parameters as a whole, it has been concluded that Kad？k？y Reservoir is in meso-eutrophic character in terms of Rotifera
