Description :
The present investigation deals with limnological profile of river Erai near Chandrapur, in Maharashtra state, India. The Chandrapur is known for hot and dry climate with an average rainfall of about 1400 mm; and is a border and backward district in eastern part of Maharashtra. Due to the rapid industrialization almost all the aquatic ecosystems have become greatly polluted with their differential impact on water quality and biodiversity therein. A year round investigation during June-2005 to May-2006 has been made on the river Erai in order to characterize the physicochemical and planktonic status of it. In physicochemical parameters, pH of water was alkaline throughout the year. TSS values were high during monsoon period due to higher amount of floating particles. The qualitative and quantitative evaluation of plankton showed high density of phytoplankton and zooplankton throughout the study period. The present study revealed that the water quality of Erai river at investigation site is mildly polluted by direct contamination of sewage and other industrial effluents.
