Study on Zooplankton Diversity in A Fresh Water Pond (Raja Bandh) of Jamtara, Jharkhand, India

Abstract

Zooplankton are cosmopolitan in nature and one of the most important ecological parameter in water quality assessment because they help in disposal of sewage and act as natural purifiers of water. Present study was carried out for a period of one-year from July 2018 to June 2019. The present study deals with Zooplankton diversity throughout the year in raja Bandh Pond of Jamtara, Jharkhand. The diversity of various types of zooplankton was studied and the result revealed that the zooplankton was represented by various genera viz., rotifera, cladocera, copepoda and ostracoda. Present study revealed 14 different species of zooplanktons belonging to 4 different classes namely 5 rotifers, 4 cladocerans, 3 copepods and 2 ostracod was observed. Rotifers were the dominant group of Zooplankton recorded with respect to diversity and population density status. Rotifers and Copepoda were the most dominant during summer than followed by Cladocerans and ostracodes. Present study revealed that the annual percentage composition comprises of 38 % rotifer, 26 % copepod, 20 %, cladocera and 16 % ostracoda respectively. Certain species viz, Brachionus sp, Daphnia sp, Cyclops sp, Cypris sp were recorded throughout the year.
