Abstract
Zooplankton samples were collected from four stations in Bayındır Dam Lake between April 2022 and January 2023 using a 60 μm plankton net with horizontal and vertical hauls, and some water quality parameters (water temperature, pH, dissolved oxygen, and conductivity) were determined in-situ. The annual mean water temperature, dissolved oxygen, pH and conductivity were 17.64±7.64 °C, 7.92±0.18 mgL-1, 9.26±1.00 mgL-1, 368.52±24.69 µS cm-1 respectively. Water quality parameters were within normal limits for most aquatic organisms. A total of 87 species were recorded in the reservoir, including 66 rotifers (75.86%), 15 cladocerans (17.24%) and 6 copepods (6.90%). A total of 22 families from Rotifera, 5 families from Cladocera and 2 families from Copepoda were recorded. Brachionidae and Lecanidae (Rotifera) having most of the species were the richest families with 10 species each. With 8 Chydoridae species from Cladocera and 5 Cyclopoidae species from Copepoda, they were discovered to be the most numerous family. It was determined that the dam lake zooplankton consisted of widely distributed cosmopolitan and eutrophication indicator species.

Water quality parameters were found to be within normal limits for most aquatic organisms. The annual average water temperature, dissolved oxygen, pH and conductivity were 17.64 ± 7.64 °C, 7.92±0.18, 9.26 ± 1.00 mgL-1, 368.52±24.69 µS cm-1 respectivelly. In the study, 66 rotifers (75.86%), 15 cladocerans (17.24%) and 6 copepod species (6.90%) were recorded in the reservoir. A total of 22 families from Rotifera, 5 families from Cladocera and 2 families from Copepoda were recorded. Brachionidae and Lecanidae from the Rotifera group containing the most species were the richest families with 10 species each. They were found to be the most abundant family with 8 species of Chydoridae from Cladocera and 5 species of Cyclopoidae from Copepodae. The most widely distributed rotifers found in all seasons during the study, Kellicottia longispina, Keratella cochlearis, Asplanchna priodonta, Testudinella emarginula, Ascomorpha ovalis, Gastropus stylifer, Filinia longiseta, Trichotria pocillum, Polyarthra dolichoptera, Polyarthra vulgaris, Synchaeta oblonga, Rotaria rotatoria. Ceriodaphnia pulchella, Bosmina longirostris, Chydorus sphaericus from Cladocera, and Cyclops vicinus, Macrocyclops albidus, Paracyclops fimbriatus and Nitokra hibernica from Copepoda had the widest range of distribution.
