BIODIVERSITY OF FRESH WATER ZOOPLANKTON OF MOUTORE RESERVOIR, PURULIA DISTRICT, WEST BENGAL.

The present study was conducted to study the zooplankton diversity, density and biodiversity indices in Moutore Reservoir, Purulia District, West Bengal, India. Monthly samples of zooplankton were collected from October, 2021 to September, 2022. The samples were observed in laboratory under light microscope and identified using standard reference books and various standard research journals. Total 21 genera of zooplankton species were identified from the Reservoir. The increased density of zooplankton was observed in pre monsoon followed by post monsoon, winter and monsoon months. Margalef's richness index (d) was higher in July month. Pielou's evenness index (J'), Shannon and Weiner index (H') and Simpson index (λ') was higher in October month. [ABSTRACT FROM AUTHOR]
