Abstract

Abundance and diversity of zooplankton with relation to physicochemical parameters in three ponds at Chittagong University campus was conducted for two years period from January 2017 to December 2018. A total of 72 samples were collected from the three ponds, whereby 33 zooplankton species belonging to five classes were identified. Among the 5 classes, Rotifera was the most dominant and abundant group which contributed 54.17%-72.73% of the total zooplankton population. The overall contribution of Rotifera was 72.73%, 54.17% and 61.90% in ponds 1, 2 and 3 respectively and among Rotifera, Brachionus was the most dominant and abundant genus. Copepoda (8.33- 14.29%) and Cladocera (9.09-25.0%) were moderately abundant and Nematoda (4.17-4.76%) and Protozoa (4.55-8.33%) were the least abundant groups in all the three ponds. Significant direct or inverse relationships of zooplankton were observed with some physicochemical parameters. Zooplankton in Pond 1 showed positive significant relationship with air temperature (r = 0.61, P
