During the present study period, a total of 43 species
of planktonic diatoms and two species of blue-green algae were recorded (Table 2). Population density of the phytoplankton
varied from 18,000 to 34,000 cellsl-1. The minimum density was
recorded during the monsoon season and the maximum
density was recorded during the summer season (Fig. 8).
Percentage composition of planktonic diatoms recorded the
minimum (75.0%) during the monsoon season and the
maximum (99.99%) during the premonsoon season.
