Abstract :

Sahni tola talab (pond) is located in the village Sundarpur Bela District-Darbhanga (Bihar). Zooplanktons are very sensitive to the change in the physical and chemical condition of water bodies. Any change in the aquatic environmental condition leads to the change in the zooplanktons communities in terms of tolerance, abundance, diversity and dominance in the habitat. Therefore, diversity of zooplanktons observation may be used as a reliable tool for bio-monitoring studies to access the pollution status of aquatic bodies. The zooplanktons diversity of the studied water body was fluctuating. There were 40 species of zooplanktons were recorded from Sahni tola talab. These zooplanktons species belonged to Protozoa, Rotifers, Cladocera, Copepoda and Ostracoda. Out of 40 species, 6 species belonged to Protozoa, 20 species to Rotifers, 7 species to Cladocera, 5 species to Copepoda and 2 species to Ostracoda. The pond receives domestic sewage water from nearby village and agriculture run off rain water. Maximum zooplankton diversity was recorded during winter season which was mainly dominated by Rotifers. These results indicate the eutrophic nature of pond. Minimum zooplankton diversity was recorded during monsoon season which may be due to high turbidity of water during monsoon.
