This study was carried out to determine the diversity, abundance, and seasonal distribution of Rotifera in Kırklareli Reservoir. Rotifera samples were collected from May 2018 to April 2019 at three stations in the reservoir and some water quality parameters were measured. The qualitative evaluation of the samples revealed the presence of 39 species in the reservoir. The quantitative evaluation of the samples showed that 24727 ind/m³ Rotifera on average was found in the reservoir. The maximum organism number was found in the summer season (45690 ind/m3). The average 27.3 % of the total annual Rotifera abundance was composed of Kellicottia longispina in Kırklareli Reservoir followed by Polyarthra dolichoptera (24.6 %), Lecane luna (6.8 %), Asplanchna priodonta (6.4%), Synchaeta oblonga (5.3%) and Synchaeta pectinate (4.9 %). Asplanchna priodonta, Synchaeta oblonga, Synchaeta pectinata, Keratella cochlearis, Keratella quadrata, Polyarthra dolichoptera, Polyarthra vulgaris and Mytilina mucronata were found the most common species in the reservoir. The water quality parameters measured in the reservoir were detected among the acceptable values to support aquatic life, especially the Rotifera community. The Rotifera densities and abundance showed a positive correlation with water temperature and Chlorophyll-a. According to these results, we conclude that Kırklareli Reservoir has an oligomesotrophic character in terms of the Rotifera fauna and the physicochemical parameters.
