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.

Bu çalışma, Kırklareli Baraj Gölü'nün Rotifera çeşitliliğini ve mevsimsel dağılımını belirlemek amacıyla yapılmıştır. Mayıs 2018 ile Nisan 2019' tarihleri arasında gölde belirlenen üç istasyonda Rotifera örnekleri toplanmış ve bazı çevresel parametreler ölçülmüştür. Rotifera örneklerin kalitatif değerlendirmesinde 39 Rotifera türü belirlenirken kantitatif değerlendirmeler sonucunda baraj gölünde yıllık ortalama 24727 ind/m³ Rotifera tespit edilmiştir. Kırklareli Baraj Gölünde en fazla bolluğa sahip olan tür Kellicottia longispina (%27,3) olurken bunu Polyarthra dolichoptera (% 24,6), Lecane luna (% 6,8), Asplanchna priodonta (% 6,4), Synchaeta oblonga (% 5,3) ve Synchaeta pectinata (% 4,9) takip etmiştir. Asplanchna priodonta, Synchaeta oblonga, Synchaeta pectinata, Keratella cochlearis, Keratella quadrata, Polyarthra dolichoptera, Polyarthra vulgaris ve Mytilina mucronata rezervuarda en yaygın türler olarak bulunmuştur. Rezervuarda ölçülen çevresel parametreler, başta Rotifera faunası olmak üzere sucul yaşamı desteklemek için kabul edilebilir değerler arasında tespit edilmiştir. Rotifera yoğunluğu ve bolluğu, su sıcaklığı ve Klorofil-a ile pozitif korelasyon göstermiştir. Bu sonuçlara göre Kırklareli Rezervuarının Rotifera faunası ve fizikokimyasal parametreler açısından oligomezotrofik bir karaktere sahip olduğu sonucuna varılmıştır.
