Diversification in phytoplankton population of Shelar Lake


Author(s): Archana Gupte

Abstract: Thane district consists of many fresh water bodies. One of them is Shelar lake, situated in the rural area of it. Three stations having environmentally different conditions such as cow shed near one station and oil runoff from nearby highway into another station were selected for the study. Phytoplankton study was carried out in a lake for a period of one year i.e. from October 2010 to September 2011.Total 19 genera were recorded belonging to chlorophyceae, cyanophyceae and bacillariophyceae. Extensive growth of phytoplankton, caused by increased amount of nutrients is a common problem in lakes. The lake shows slight eutrophication in the pre monsoon period which reduces the clarity of water and has depletion of oxygen content. It was observed during the study that some of the members of chlorophyceae, bacillariophyceae and cyanophyceae show their appearance only during premonsoon. Phytoplankton responds rapidly to the condition changes. Conditional changes result in the formation of high compositional diversity. Phytoplankton like Navicula, Nostoc, Microcystis, make their appearance in large quantity during premonsoon indicating the lake is polluted. Phytoplankton belonging to Chlorophyceae group shows domination on cyanophyceae and bacillariophyceae group.
