abstract
The present investigation of seasonal variation of Zooplankton in Som Kamla Amba Reservoir was conducted to check the zooplankton status in the reservoir and provide new insights into its ecology. The study was carried out during the period of one annual cycle i.e. February 2015 to January 2016. A total of 23 genera were found in this reservoir. Among these, rotifers comprise of 5 genera (28.9%), Cladocera 4 (19.638%), Copepods 3 (20.09%), Ostracoda 4 (19.317%) and Protozoa 7 (12.02%). The season wise zooplankton analysis showed that the number of population was highest during summer, followed by monsoon and lowest during winter.
