Abstract :
The present investigation was an attempt to study the zooplankton community of
Sathanur reservoir of Thiruvannamalai, Tamilnadu, India. The zooplankton species composition
was studied for a period of one year from October 2018 to September 2019 on monthly interval basis.
As a result of study, 24 zooplankton species were identified, out of which 9 were Rotifers, 7
Cladocerans, 5 Copepods and 3 Ostracodans. The overall population density of zooplankton was
found maximum during the summer season and mininmum during monsoon. They play a supportive
role in fish culture by recycling of nutrients and increase the soil fertility and involve in energy
transfer between phytoplankton and fishes.
