Zooplankton of Karasu River (Türkiye)

Öz

In this research, species identifications were made by monthly on-site measurements (Temperature, dissolved oxygen, pH,) and taking zooplankton samples from the sampling points determined on the Karasu River between January 2019 and December 2019. A total of 49 zooplankton species were identified in the study. Among these species, 35 species of Rotifera, 11 species of Cladocera and 3 species of Copepoda. Species belonging to Rotifera constituted 71.4% of the total zooplankton, 22.5% of Cladocera and 6.1% of Copepoda. During the research, zooplankton species were recorded every month. While increases were observed in zooplankton density and individual numbers in the spring, summer and early autumn months, decreases were observed in the number of zooplankton species and individuals in winter months

Karasu Nehri (Türkiye) Zooplanktonu

Öz

Bu araştırmada, Ocak 2019 ile Aralık 2019 tarihleri arasında Karasu Nehri üzerinde belirlenen örnekleme noktalarından aylık olarak yerinde ölçümler (Sıcaklık, çözünmüş oksijen, pH,) yapılarak ve zooplankton örnekleri alınarak tür teşhisleri yapılmıştır. Çalışmada toplam 49 zooplankton türü teşhis edilmiştir. Bu türlerden 35 tür Rotifera, 11 tür Cladocera ve 3 tür Copepoda grubundandır. Rotifera’ya ait olan türler toplam zooplanktonun %71,4, Cladocera %22,5 ve Copepoda %6,1’lik kısmını oluşturmuşlardır. Araştırma süresince her ay zooplankton türleri kaydedilmiştir. İlkbahar, yaz ve sonbahar aylarının başlarında zooplankton yoğunluğu ve birey sayılarında artışlar gözlenirken kış aylarında zooplankton tür ve birey sayılarında azalmalar kaydedilmiştir.
