Seasonal variations in ostracod species in two freshwater lakes in Yavatmal District (Maharashtra) India

Abstract

The diversity and density of ostracods (zooplankton) in two freshwater lakes in the Yavatmal district of Maharashtra, India, were studied from June 2020 to May 2021 to determine seasonal variations. Plankton net (64m pore size) was used to collect the samples and analysis was performed using standard keys. In all, 11 species from 8 genera belonging to 3 families of Ostracoda were identified from Mama Lake and Singhada Lake of the Yavatmal district of Maharashtra, India. The overall population of Ostracoda is greater in Mama Lake than in Singhada Lake. Additionally, the species diversity was higher in the summer season and lowest in winter.
