“…Determining the physico-chemical properties of the KDL water and the seasonal and spatial biomarker levels of copepod living in this reservoir are important in terms of evaluating the health of the reservoir. Temperature is the vital factor that affects the metabolic activities of aquatic organisms (Akther et al, 2018;Bulut et al, 2021). The water temperature of KDL varied between 8-30.4 ºC (Table 1).…”

In this study, the zooplankton community and its relationship with environmental factors were investigated in the Karakaya Dam Lake (KDL). The physico-chemical characterization showed that there were obvious changes in the water quality and zooplankton population structure, which was mainly due to the organic matter source. Reactive phosphate (SRP) and nitrogen values were found in low concentrations. A total of 22 zooplankton taxa were determined, including 14 taxa of Rotifera, followed by 6 taxa of Cladocera and 2 taxa of Copepoda. The most abundant species were Synchaeta oblonga (Rotifera), Bosminia longirostris (Cladocera), and Cyclops scutifer (Copepoda). The abundance of zooplankton was highest in spring. Canonical correspondence analysis (CCA) was used to examine relationships between measured environmental variables and zooplankton composition. According to CCA, dissolved oxygen, and SRP values, there was a significant relation to zooplankton abundant with these factors. The triplots diagram demonstrated variations of the structure of zooplankton population composition which can be explained by the environmental variables. Oxidative stress (catalase, glutathione S-transferase, glutathione reductase) and neurotoxicity (acetyl cholinesterase) biomarkers were analyzed in copepod species. Glutathione reductase and acetyl cholinesterase activities were significantly inhibited in the summer. Catalase activity was induced in the spring. The seasonal changes of biomarker indicated that the KDL may be at risk of pollution that originated from agricultural and industrial activities.

“…In this study, the mentioned species had pH 8.1-8.8, dissolved oxygen values 5.8-12.2 mg/L, temperature 3.9-24.6 °C, and electrical conductivity values between 341-434 µS/cm. As seen in the Işıklı Dam lake, most lakes and dam lake ecosystems are dominated by Rotifera, followed by the Cladocera and Copepoda groups (Tuna and Ustaoğlu, 2016;Tugyan and Bozkurt, 2019;Golec-Fialek et al, 2021;Bulut et al, 2021). Calanoid and cyclopoid copepod species are important criteria in defining water resources' quality and trophic status (Muñoz-Colmenares et al, 2021).…”

“…Zooplanktonic organisms constitute the primary food source of fish in freshwater sources and they constitute the leading food of many pelagic-feeding fish species and young periods of demersal-feeding fish (Gürleyen and Ustaoğlu, 2017). Zooplanktonic organisms, which form the second food pyramid ring in fresh waters, are essential in ensuring the continuity of the material and energy cycle (Bulut et al, 2021). Rotifera group is an indicator for determining water quality and trophic status (Muñoz-Colmenares et al, 2021).…”

In this study, the zooplankton distribution and composition of Işıklı Lake, located in the Inner West Anatolia region of Türkiye, were examined monthly between 2003-2005. Zooplankton samples were collected with Hydro-Bios plankton net (55 µm) at the surface and fixed in formaldehyde (4 %). Physiological parameters such as surface water temperature, pH, dissolved oxygen, and conductivity were also measured. Also, the frequency index (F %) and the Brachionus / Trichocerca (QB/T) were determined to assess the trophic composition of Lake Işıklı. A total of 49 species have been identified. Rotifera (55 %), Cladocera (27 %) and Copepoda (18%) were represented by the species. The maximum species was found in May 2004 (21 species), while the minimum was found in October 2003 (5 species). Asplanchna priodonta, Keratella cochlearis, Keratella tecta, Polyarthra dolichoptera, Synchaeta pectinata, Bosmina longirostris and Chydorus sphaericus are common species in the lake. The water temperature varied between 3.9-24.6 °C; pH ranged from 8.1 to 8.8; the electrical conductivity ranged from 341 µS/cm to 434 µS/cm; the dissolved oxygen values changed from 5.8 mg/L to 11.1 mg/L. According to the frequency index (F %), the most dominant species are B. longirostris (74 %), K. cochlearis (62 %), A. priodonta (54 %), and C. sphaericus (51 %). A total of 20 species are reported for the first time from the region. Newly reported species from the lake were: the rotifers, A. priodonta, Brachionus angularis,
