Collecting and processing the zooplankton samples followed established standards [7]. For qualitative
analysis of zooplankton, samples were collected by means of horizontal haul, using plankton net (No.25)
with a mesh size of 64 μm. Collected samples were transferred to labeled vial bottles containing 4%
formalin. Zooplankton samples were identified to the lowest taxonomic units possible. Identification of
zooplankton species was based on relevant literatures
