Abstract

The distribution and periodicity of phytoplankton in Khaji Kotnoor reservoir of Gulbaraga region was investigated. The dominant phytoplankton of different algal groups was recorded and identified in different seasons. To know to the variations in periodicity and distribution of phytoplankton, various physico-chemical and biological parameters of the water body have been observed for the period of two years from Nov. 2001 to Oct. 2003. The observations indicated that high level of pH, temperature, total alkalinity, oxygen, chloride, nitrate, phosphate, total hardness, TDS and BOD influence the growth of phytoplanktonic groups in the reservoir.
