Abstract

The abundance, distribution and composition of various groups of zooplankton; Nauplii, Copepoda, Rotifera, Cladocera and Ostracoda inhabiting Bolgoda Lake 11, Sri Lanka were studied. Some physical factors influencing the seasonal abundance and pattern of fluctuation were described. This investigation revealed that wind and rainfall were the major factors that contributed to the abundance of the zooplankton population during the monsoonal periods. The nauplii and the copepoda contributed about 70% of the zooplankton in the lake and their densities varied with depth.
