2019, Journal of limnology and freshwater fisheries research

Some water quality parameters (Secchi disk depth, water temperature, dissolved oxygen, pH, conductivity, chlorophyll a, NO2-N, NO3-N, NH4-N, PO4-P) and zooplankton fauna were determined in the Kozan Dam Lake. While the quality of the reservoir water was first class water in terms of temperature, dissolved oxygen, NH4-N, PO4-P, it was second-class water in terms of conductivity, pH, NO3-N. In total, 50 zooplankton species belonging to 26 families were determined (29 species belonging to 17 families from Rotifera, 15 species belonging to 7 families from Cladocera and 6 species belonging to 2 families from Copepoda). Brachionidae (Rotifera) was the most species rich family with 7 species, followed by Chydoridae (Cladocera) and Cyclopidae (Copepoda) with 6 and 5 species respectively. The most dominant species were Synchaeta pectinata (38.33%) from Rotifera, Bosmina longirostris (5.71%) from Cladocera and Cyclops vicinus (0.67%) from Copepoda. At the same time, the species found in every month were Asplanchna priodonta, Polyarthra dolichoptera, Bosmina longirostris, Ceriodaphnia pulchella, Cyclops vicinus and Diacyclops bicuspidatus. In the study, Rotifera was the most abundant group with 67%, followed by Cladocera with 29% and Copepoda with 4%. On the other hand, total Rotifera was found mostly in December (10099 individual/ m 3), Cladocera in January (4928 ind./m 3) and Copepoda in September (1091 ind./m 3).
