Biomass composition of phytoplanktons in Mahakali River, Nepal

Abstract

Phytoplankton biomass composition of Mahakali River has been studied. Samples were collected twice a month at an interval of 15 days for two years from September, 2003 to August, 2005. It was observed that the average annual biomass of phytoplankton community was 10.494 mg/m 3 during the first year and 8.057 mg/m 3 in the second year of the study. The peak of biomass was obtained in the month of May (15.276mg/m 3 ) and March (11.183mg/m 3) during the first and second year, respectively. The lowest values of biomass were recorded in the month of September (0.989mg/m 3) and August (0.842mg/m 3) during the respective years.
