Abstract
Diversity of zooplankton was studied in three selected paddy fields (PF) of Imphal West District in Manipur namely, Wangoi (PF1), Hiyangthang (PF2), Mayang Imphal (PF3) during August to October, 2020. The study revealed that altogether 55 taxa comprising of 44 rotifera, 8 cladocera and only 3 copepoda (fig2) had occurred in the three studied paddy fields. The highest number of zooplankton taxa (rotifer) was observed at PF1followed by (cladocera) at PF3 and (copepoda) at PF2. Nine physico-chemical parameters of water in the three study areas was also analysed The PH value ranged between 6.0 and 8.0, Temperature between 27 and 300C, Dissolved oxygen between 2.0 and 6.0mg/l, Free Carbondioxide between 3.0 and 11.0 mg/l, Chloride between 3.0 and20.0 mg/l, Acidity between 5.0 and 18.0 mg/l, alkalinity between 22.0 and 95.0 mg/l, Nitrate between 0.03 and 0.06mg/l, and Nitrite between 0.01 and 0.05 mg/l. as observed during the investigation period (Table -3).
