Seasonal Distribution of Rotifera Compositions and Abundance in Kayalıköy Reservoir (Kırklareli/Turkey)

Abstract

This study was carried out to determine the diversity, abundance seasonal distribution of Rotifera in Kayalıköy reservoir. Rotifera and water samples were collected monthly intervals from May 2018 to April 2019 in three different stations in the reservoir and some environmental parameters were also measured. A total of 40 species from Rotifera were determined in the reservoir. The quantitative evaluation of the Rotifera samples were found an average of 27938 ± 18992 ind/m3in the Kayalıköy reservoir. The maximum numbers of Rotifera in the reservoir were found in autumn (42966 ind/m3) and at 2nd station (33487 ind/m3), the minimum numbers were recorded in winter (1474 ind/m3) and at 1st stations (24850 ind/m3). The most common species in the reservoir were found Brachionus quadridentatus, Keratella cochlearis, K. quadrata, Synchaeta pectinata, Asplanchna priodonta, Polyarthra vulgaris and Filinia longiseta. According to the water quality standards of Turkey, the water quality of Kayalıköy reservoir was found Class I and A1. When we examined the species identified in the reservoir, the distribution of the individuals that make up the Rotifera fauna and physicochemical parameters as a whole, it has been concluded that Kayalıköy reservoir has water suitable for drinking, agricultural irrigation and aquaculture and it’s classified as oligomesotrophic character.
