Study on Zooplankton Diversity of Cauvery River in Erode District, Tamil Nadu

Many places in Tamilnadu rely on the Cauvery River for their water supply. The Erode District is heavily polluted as a result of poor textile effluent control. The purpose of this study was to assess the quality of the Cauvery River in Erode. Planktons are an aquatic ecosystem's primary food source. One of the most significant ecological indicators for assessing water quality is zooplankton diversity. The purpose of this study was to examine the diversity of Zooplankton in the Cauvery River in Erode from July to November 2018, and the results were documented on a periodic basis. The findings demonstrated that Zooplankton diversity is a valuable indicator for the river ecosystem and is impacted by river water quality.In the Cauvery River, the Rotifers are the most regularly observed and prominent zooplankton species. Water quality can be related to variations in biodiversity in a body of water.Zooplanktons are also effective biological water quality indicators.
