Hydrobiogical Parameters Studies of the Alagankulam River, Ramanathapuram District, Tamil Nadu, India.

ABSTRACT

The present study was carried out to determine the pysico-chemical characteristics and nutrients in two stations of Alagankulam River, Ramanathapuram, and South East Coast of India during January to December 2012. All the pysico-chemical parameters were analyzed using standard methods (Apha, 1998). The minimum and maximum values of water temperature (°c), Dissolved oxygen (mg/lit), Salinity (ppt), PH, Calcium (mg/lit) was 26-35 (Station 1), 26-35 (Station 2), 5.0-7.1 (S1), 5.0-7.1 (S2), 0.01-0.06 (S1), 0.02-0.07 (S2), 7.0-8.2 (S1), 7.2-8.3 (S2), 22.1-29.4 (S1), 19.9-26,2 (S2) respectively. The range of Alkalinity (mg/lit), Silicate (mg/lit), Sulphate (mg/lit), Chloride (mg/lit), Ammonia (mg/lit), Phosphate (mg/lit) and nitrite (mg/lit) was 16.1-28.6 (S1), 18.5-26.8 (S2), 0.13-2.28 (S1), 0.81-1.74 (S2), 26.13-41.29 (S1), 28.9-49.70(S2), 6.1-8.7(S1), 5.5-7.9 (S2), 0.2-1.9 (S1), 0.2-1.9 (S2), 3.3-9.2 (S1), 1.3-8.5 (S2), 13-28 (S1) and 12-27 (S2) respectively.
