Water resources are declining day by day at the faster rate due to rapid urbanization and population load. Deterioration of the water quality is now a global problem (Mahananda et al. 2010). The purity of water varies from place to place in nature (Patil 2013). The quality of water of any aquatic ecosystem arises by the interaction of physical chemical and biological component of the habitat. Aquatic biota presents in any aquatic ecosystem directly influence the Physico-chemical characteristics of that aquatic ecosystem.
