Abstract

• Investigation on the species diversity of zooplankton species and water parameters in Naung Tong Lake were conducted during March, 2019 to January, 2020. A total of 17 zooplankton species, of ten genera, six families and four orders were recorded. Based on the relation between water parameters and zooplankton, the moderate positive relationship was observed between pH and zooplankton population. Other parameters (such as water temperature, turbidity, DO and BOD) and zooplankton were poorly correlated. This study revealed that physico-chemical fluctuations were negative impact on the zooplankton species richness and abundance in this lake.
