Zooplankton play a crucial role in estuarine ecosystems by linking primary producers with higher trophic levels and contributing significantly to fisheries productivity. The present study was carried out in the mangrove-associated estuarine regions of Pora and Pallam villages to examine seasonal variations in zooplankton diversity and their relationship with environmental parameters. Samples were collected during March (summer) and June (monsoon) using a standard zooplankton net, alongside measurements of light intensity, temperature, and water quality.The results revealed higher zooplankton diversity and abundance in the summer season compared to the monsoon. Favorable conditions such as greater light penetration and stable hydrography in summer enhanced phytoplankton productivity, which in turn supported rich zooplankton communities. In contrast, monsoon conditions considered by reduced light intensity due to cloud cover and increased turbidity from freshwater inflows adversely affected phytoplankton growth, leading to a decline in zooplankton populations. The study identified copepods (particularly Calanoid species) and rotifers as dominant taxa across both seasons. Environmental factors, especially light intensity and temperature, strongly influenced zooplankton growth, while phytoplankton abundance emerged as the primary determinant of community structure. The findings emphasize the direct dependence of zooplankton on phytoplankton availability and highlight their role as indicators of estuarine ecosystem health. As plankton populations are directly proportional to fisheries productivity, this study provides important baseline information for the ecological assessment and sustainable management of mangrove estuaries.
