Abstract
A study was carried out in Matthur tank near Shivamogga city on Physico-chemical characteristics and Planktonic composition. The results of physico-chemical parameters were compared with the standard values prescribed by the Bureau of India Standards (BIS) and World Health Organization (WHO). The study revealed that tank water is polluted as it possesses high BOD, CO2, phosphate and nitrogen. A total of 55 species belonging to 38 genera of phytoplanktons were recorded, of which chlorophycean and diatoms were dominant. Nine zooplanktons and twelve macrophytes were also recorded.
