Seasonal variation of the physicochemical factors and plankton community in a freshwater fish pond at Burdwan, West Bengal were studied from January to December, 1971. Water temperature varied from 20.0°C in January to 32.6°C in June. Total plankton volume varied from 8.7 to 14.2 ml and the maxima were recorded in February (spring) and July (monsoon) and the minima appeared in April (summer) and November (autumn). It was observed that the spring maximum was dominated by zooplankton while the monsoon maximum was dominated by phytoplankton. The rotifers constituted the most abundant group of zooplankton. Water-blooms of blue-green algae were recorded from the monsoon period to autumn. A positive correlation between the phosphate content of the water and the zooplankton was observed.
