Description 1660-1668
Present article consist the hydrographical and chemical parameters examined on the Satyavaram pond near Narasannapeta of Srikakulam District. Water samples were analyzed for Physical and Chemical parameters. Average values of pH, turbidity, conductivity, dissolved oxygen, B.O.D, carbonate, bicarbonate, dissolved solids, chloride, fluoride, ammonia, nitrate, phosphate, silicate for two years were 7.21, 18.40NTU, 673µMhos, 6.16mg/lit, 3.43mg/lit, 3.08mg/lit, 180mg/lit, 347.4mg/lit, 106.6mg/lit, 0.15mg/lit, 2.57µg/lit, 7.69µg/lit, 2.08µg/lit and 29.2µg/lit respectively. Observations of the Satyavaram Pond revealed that the dominant members belonged to Chlorophyceae (44 genera) followed by Cyanophyceae (20 genera), Bacillariophyceae (15 genera) and Euglenophyceae (3 genera). Abundance of various algal groups in this pond were in the percentage of Chlorophyceae 60.95%, Cyanophyceae 20%, Bacillariophyceae 15.55% and Euglenophyceae with 3.5% in two year study. Interrelationship between environmental, physico-chemical parameters and phytoplankton (Pearson’s Correlation matrix) was also studied. In this investigation, atmospheric temperature showed significant positive correlation with turbidity (r=0.6493) and rainfall showed positive correlation with RH (r=0.7968). Turbidity showed positive correlation with silicate (r=0.6913) and Conductivity showed positive correlation with TDS (r=0.947). Similarly, Bacillariophyceae members showed significant positive significant positive correlation with Cyanophyceae members (r=0.5473).
