Abstract: A study was undertaken to record the seasonal fluctuation in phytoplanktons and zooplanktons population in Muthupet estuary, Thiruvarur District, Tamil Nadu, India, for a period of two years (July 2012 to June 2013). In this study, Out of the 20 species, 13 were diatoms, 6 were Chlorophyceae (green algae) and 1 was cyanophyceae. In general, the diatoms ranked first in abundance followed by Chlorophyceae (green algae) and cyanophyceae among the total phytoplankton. Throughout the study period, out of 21 species of zooplankton, 7 were Protozoa, 7 were Rotifer, 4 were Cladocera and 3 were Coppepod identified in Muthupet estuary. The protozoa and rotifer constituted the major component of the zooplankton population throughout the study period. In general, the seasonal population density was maximum during summer and pre monsoon periods. Minimum population density was found during monsoon period.
