Abstract

Plankton have immense value as food and play an important role in disposal of sewage and natural purifiers of water. Zooplankton diversity is one of the most important ecological parameter in water quality assessment. In this study we try to assess the seasonal zooplankton species richness and diversity, for a period of One-year (April 2014 – March 2015) data on the seasonal studies of zooplankton diversity of jubilee pond, Chaibasa, West Singhbhum, Jharkhand, India revealed the presence of 29 zooplankton species. A limited number of these were recorded throughout the year, while others were distributed in different seasons mainly in winter and summer seasons. During winter, Cladocerans were the most dominant group followed by Copepoda. On the other hand, rotifers and Cladocerans were the most dominant during summer. Certain species e.g. Brachionus calyciflorus, Brachionus falcatus, Monostyla quadridentatus, Trichotria sp., Cyclops sp., Cypris sp., and Daphnia carinata were recorded throughout the year. Physico-chemical analysis of Temperature, pH, dissolved oxygen, free carbon-di-oxide, alkalinity, chlorinity, salinity, total hardness, and phosphorus were observed during the study period.
