It was found that among water quality parameters, sechi depth, temperature, silica, Ca and CaCO3 amounts were higher in the first (referans) station; while conductivity, dissolved oxygen, pH, chlorophyll a, nitrate and phosphate values were higher in second (cage) station. A total of 57 taxa were identified in the study. Of these taxa, 33 belonged to Rotifera, 14 belonged to Cladocera and 10 belonged to Copepoda. It was found that Keratella cochlearis, Daphnia longispina, Cyclops vicinus, Acanthodiaptomus denticornis were the most common throughout the year, while Ascomorpha ovalis, Dicranophorus epicharis, Keratella tecta, Notholca acuminata, Testudinella patina, T. mucronata, Trichotria pocillum, Disparalona rostrata, Scapholeberis kingi, Leydigia leydigi, Alona guttata, Eucyclops speratus, Paracyclops chiltoni were the least species. Monommata longiseta, Trichocerca porcellus, Diaphanasoma birgei, Eurycercus lamellatus were only found in the first station, while Ascomorpha ovalis, Notholca acuminata, Rotaria neptunia, Trichotria pocillum, Disparalona rostrata and Eucyclops speratus were only found in the second station. Rotifera was represented with higher number of species in first station for 5 months but Copepoda was represented with higher number of species in second station for 5 months. The abundance of groups according to months and stations revealed that Rotifera and Copepoda were abundant quantitatively in first station for 7 months; while Cladocera was abundant in first station for 8 months. On the other hand, amount of all zooplankton species were found to be more abundant in cage station in April (6605 ±4597.35 individual m-3) and more abundant in first station in September (1635 ±2384.852 individual m-3) (P > 0.05).

It was established that total zooplankton in the reservoir is being represented with 18 species belonging to Cladocera and Copepoda. Number of the species belonging to cladocer and copepod are 14 and 4, respectively. Contrary to the number of species, abundance was found to be in favor of copepods (65.99% of total zooplankton). Remaining one third of total zooplankton (34.01%) was cladocerans. The most abundant species were determined as Bosmina longirostris among cladocerans and Thermocyclops vermifer persicus (Lindberg, 1936) among copepods. Monthly depth of light penetration zone (photic zone) was calculated using Secchi disk readings. It was observed that the copepods were more abundant than the cladocerans in the light penetration zone (photic zone). Beyond the light penetration zone the situation was reversed and the cladocerans were found to be more abundant than the copepods. Chlorophyll-a level was also examined in the lake. Since this study is the very first study carried out on the zooplankton of Aslantaş Dam Lake, all of the species observed are the first reports for Aslantaş Dam Lake.

Fourteen (14) species of Rotifera (46.67%), 10 species of Copepoda (33.33%), and 6 species of Cladocera (20%) were recorded. It was observed that the most widely distributed species are Rotaria neptunia (7 wells), Keratella quadrata (5 wells), Daphnia curvirostris (8 wells), Coronatella rectangula (in 6 wells), Chydorus sphaericus and Pleuroxus aduncus (5 wells each), Megacyclops viridis (8 wells) and Tropocyclops prasinus (in 6 wells). Most species (14 species) were found in well 8, followed by wells 3, 5, 7 and 9 with 11 species. There was a significant and positive relationship between zooplankton species diversity, abundance, and water quality parameters. It can be concluded that some of the rotifer and cladocer species and most of the copepod species in the study are groundwater compatible species.

In this study, Copepoda and Cladocera (Crustacea) fauna of the Asi River, a very importent river in the Eastern Mediterranean, was investigated qualitatively throughout one year (September-1996 and August-1997) in the province of Hatay, the Turkish part. The samples were obtained monthly from 5 stations through a plankton net of 60 µm mesh size and were preserved in 4% formaldehyde. A total of 22 species (15 Cladoceran and 7 Copepoda) were identified. Bosmina longirostris (O.F.Muller, 1785) belonging to the Cladocera species was observed throughout most parts of the year, Nitocra hibernica (Brady, 1880) which belongs to the Copepoda was observed throughout 12 months, and finally Cyclops vicinus Uljanıne, 1975 was observed throughout 11 months.

A total of 3 families were detected from Rotifera and Lecanidae was the richest family with 8 species. Among the 6 families of Copepoda, Cyclopoidae had 8 species. The rotifer species with the largest distribution areas were Lecane closterocerca (found in 15 wells), Pleuroxus aduncus, the only species from Cladocera, was found in 21 wells and Kinnecaris xanthi had the widest distribution area (found in 27 wells). In terms of total zooplankton species, it was determined that wells 3, 12, and 18 were the richest with 14 species. While Rotifera was found in limited quantities in all water wells, Pleuroxus aduncus from Cladocera, Diacyclops longuioides, Megacyclops viridis, Monchenkocyclops mehmetadami and Thermocyclops dybowski from Copepoda were found in very large quantities. In addition, the genus Ectinosoma is rep...

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...
