Studies on Physico-Chemical Parameters in Two Different Stations in Nagore Cauvery River Basin and Pattanachcheri Village at Nagore Coastal Region, Southeast Coast of Tamilnadu

The present study was determine the Monthly variations of physico-chemical parameters viz Temperature, Salinity, pH, Dissolved Oxygen and Nutrients of the environment and are the factors which mainly influence the production and successful propagation of planktonic life in the coastal biotopes. The ranges of values of atmospheric and surface water temperature (0C) 23 - 29C and 24 - 31C, salinity () 6 - 35, pH 7.7 - 8.4, dissolved oxygen (ml l-1) were 3.07 - 5.66. The values (Cg l-1) of nutrients were nitrate (M) 0.84 - 13.5, nitrite (M) 0.07 - 1.89, phosphate (M) 0.06 - 4.58, silicate (M) 17.96 - 237.67 respectively.
