Abstract

Seasonal variations of zooplankton have been carried out at five selected sites on streams flow into the zab river. The present study was conducted to determine zooplankton fauna of five selected sites during Spring 2018 and Winter 2019 seasonally. The zooplankton samples were collected by using plankton net with the mesh size of 55μm horizontally and preserved in 4% formaldehyde. Total 35 taxa (31 species from Rotifera, 3 species from Cladocera, and 1 species from Copepoda) were identified in this study. Dominant groups were Rotifera, Cladocera followed by Copepoda. Zooplankton samples were consisted of 88% Rotifera, 9% Cladocera, and 3% Copepoda.
