Abstract
Aquatic ecosystem is the most diverse ecosystem in the world. The first life originated in the water and first organisms was also aquatic where water was the principal external as well as internal medium for organisms. Water is one of the most common and the large precious resources on world. Ground water resources have been contaminated by organic, inorganic and biological pollution. Therefore management of aquatic ecosystem in particular has become a main concern in the present years. Surface water samples were collected from Cauvery estuary are during the period of January 2016 to December 2016. The pH meter was used to determine the pH and Temprature, The Dissolved oxygen, silicate. Estimate of phosphate, Nitrate was handled. Based on the present study, it may be concluded that the physicochemical characters vary in each month according to the ecological influence.
