Türkçe

Arastirma, Hatay il sinirlari icerisinde bulunan Golkent 1 Rezervuari; Golkent 2 Rezervuari ve Topbogazi Goleti’nde 2009 yilinda mevsimsel olarak yurutulmustur. Orneklemenin yapildigi her uc rezervuarda da sicaklik kisin dusuk belirlenirken ayni donem icin cozunmus oksijen yuksek bulunmustur. Sicakligin yuksek bulundugu yazin ise cozunmus oksijen dusuk degerlerde bulunmustur. pH degerlerinin ise mevsime bagli onemli bir degisim gostermedigi belirlenmistir. Calismada Kladoser grubundan 8 tur ve kopepod grubundan 7 tur olmak uzere toplam 15 tur belirlenmis, en cok tur (15 tur) ilkbaharda bulunmus ve kladoserlerden Bosmina longirostris , kopepodlardan Cyclops vicinus ’un en fazla bulunan turler oldugu belirlenmistir. Kladoser ve kopepod turlerinin cogunun kis mevsiminde daha buyuk boylu olduklari belirlenmistir. Moina micrura , Ceriodaphnia pulchella , Diaphanosoma birgei , Alona rectangula Eudiaptomus drieschi her mevsim, Chydorus sphaericus ’un kis haric uc mevsim yumurtali bireylerine rastlanmistir.

While temperature was lower in winter in every sampling localities, dissolved oxygen was high for the same period. When the temperature was found high in summer, dissolved oxygen was found low. pH values did not show change depending on the season. In the study, 7 species from Copepoda, 8 species from Cladocera, a total of 15 species were identified. Most species (15 species) were found in the spring, and Bosmina longirostris and Cyclops vicinus determined to be the most abundant species. It was determined the body length of most species reached in winter season. Moina micrura , Ceriodaphnia pulchella , Diaphanosoma birgei , Alona rectangula, Eudiaptomus d rieschi produced eggs all sampling periods and Chydorus sphaericus produced three sampling periods except winter.
