Seasonal Diversity of Copepods in Relation with Physico-Chemical Status of Kolar River, Saoner, Dist. Nagpur (Maharashtra State), India

Abstract

The present study is focused on the seasonal variations of copepods in relations with the physic-chemical parameters of Kolar River Seasonal changes in physic-chemical parameters such as water temperature, pH, dissolved oxygen and inorganic contents were studied month wise from June 2011 to May 2012. Studies showed the seasonal fluctuations in water temperature (20.2◦c to 27.3◦c), conductivity (277μS/cm to 401μS/cm), pH (7.6 to 8.5), total alkalinity (146 mg/l to 186 mg/l), dissolved oxygen (5.9 mg/l to 10.1 mg/l), phosphates (0.043 mg/l to 0.067 mg/l), nitrates (0.018 mg/l to 0.025 mg/l). Copepods were recorded as 225 No./L. The study revealed that there is an indication of pollution in the river due to anthropogenic activities, rapid civilization in that area and domestic sewage. Hence preventive measures are required to avoid further deterioration of the river water quality.

Keywords: Kolar river, physico-chemical, anthropogenic activities, seasonal diversity, Copepods, Saoner.
