Spatial and Temporal Changes of Planktonic Microcrustaceans (Cladocera, Copepoda) and its Relationship with Physicochemical Parameters in K?rklareli Reservoir (K?rklareli-Turkey)

This study focused on monthly densities and abundance of planktonic microcrustaceans (Cladocera Copepeda) in K?rklareli reservoir, as well their relationship with some physicochemical parameters at three different stations for the period from May 2018 to April 2019. In present study, a total 26 species, 14 Cladocera 12 Copepoda were identified. The most common species reservoir B. longirostris, D. pulex, cucullata galeata, longispina brachyurum C. abyssorum, vicinus, E. vulgaris A. wierzejski Copepoda. annual mean recorded during (24076 ind/m3) 67 % (16054 ± 12414 33 (8022 5564 ind/m3). maximum found September (51521 minimum was January (2919 environmental measured detected among acceptable values support aquatic life, especially zooplankton community. showed positive correlation water temperature Chlorophyll-a, while hyalina, cucullata, longirostris ovalis staphylinus, T. crassus, M. albidus, robustus, leuckarti, viridis affected by similar conditions. According these results, we conclude that has mesotrophic character terms microcrustacean fauna parameters.
