摘要：The present investigation was undertaken to study the impact of anthropogenic activities such as Ganeshidol immersion and mattresses washing during the Navaratra festival on the phytoplankton diversity of Rajaramreservoir. The total number of phytoplankton recorded during this investigation is 120. Several of these algalspecies belong to the pollution tolerant genera. A few biological and diversity indices were also calculated,which indicate high level of pollution of the Rajaram reservoir. Therefore, it is an urgent need to conserve thisreservoir for the future water resource.
