ABSTRACT
Living organisms need water for their growth and survival. Almost every aspect of life on our planet is governed by water. Discharge of toxic chemicals contaminate the water bodies with unwanted substances, which cause excessive algal growth and degrade the water quality. Water bodies such as ponds, reservoirs and lakes, contain plankton whose growth and distribution is influenced by and their physico chemical parameters. Zooplankton play a vital role in the maintenance of aquatic ecosystem and also are important intermediates in the food chain, and therefore, their survival and maintenance serve as good indicators of water pollution. Their successful growth and survival is dependent upon the various biotic and abiotic factors such as light , temperature, dissolved oxygen content etc. In the present study, a reservoir named Dindi was selected, to learn about the zooplankton population which serve as indicators to know about the pollution of this reservoir. This is reservoir is constructed across Dindi river located in Dindi, Nalgonda District, of Telangana India. Thirteen physico chemical parameters such as temperature, dissolved oxygen, pH etc were studied, during the period between 2011-2016. Fluctuations in dissolved oxygen, nitrates, sulphates were observed, which seem to impact the zooplankton of this reservoir. This study is first of its kind, on this reservoir, and gave us valuable insights regarding the pollution levels of this water body.
