Abstract

This study was carried out to assess the plankton diversity of Kumri beel, Goalpara district of Assam for a period of one year from April 2018 to March, 2019. Planktons were sampled in the morning hours between 6.00 and 8.00 AM by filtering 100 liters of water through standard plankton net of 70 micron (µ) mesh size. The samples were analyzed using Past software. The study revealed very rich diversity of phytoplankton including Chlorophycae, Cyanophycae, Flagellates, Euglenophycae, Bacilariophycae and Dianoplagelates and zooplankton including protozoan, Rotifer, Copepoda and Cladocera. The diversity indices analysis of Margalef D index, Shannon-Weiner and Simpson’s index of diversity shows that monsoon season has the highest diversity than the other seasons whereas phytoplankton were highly dominated during the premonsoon season. Though the study revealed very rich diversity of population of plankton which indicates suitability to pisciculture the beel is under threat due to anthropogenic factors and in urgent need of conservation. Therefore strict implementation of fishery laws and permission of the brick industries should be totally restricted.
