Thirunavukkarasu K, Soundarapandian P, Varadharajan D and Gunalan B

The study of physico-chemical properties of coastal environments is important, because the variations in the physicochemical properties were influence on the floral and faunal production. During the study period, the maximum and minimum values of rainfall, water temperatures, salinity and dissolved oxygen recorded were 16.76mm to 745.76mm, 24 to 33°C, 24 to 37% and 3.8 to 4.6 ml/l for both the stations. And the dissolved nutrients of nitrite, nitrate, ammonia, inorganic phosphate and reactive silicate recorded were 0.83 to 5.62 μM, 10.3 to 25.6 μM, 0.11 to 5.62 μM, 0.52 to 3.76 μM and 30 to 123 μM for both the stations respectively. The variable of physico-chemical parameters is mainly affect the species diversity, pattern of diversity, reproduction, spawning, survival and other activities. To maintain optimum level of water quality parameters this is better to species survival and healthy ecosystem.
