The seasonal diversity of different types of zooplankton was obserevedfor theHiran-II reservoir, Umerethi, Saurashtra region of Gujarat, India. The samples were collected from the surface water with the help of a plankton net having amesh size of 64 µm. The samples were preserved for further analysis. The zooplankton specieswere identified using key references. The zooplankton population showedthe correlation with the parameters of water temperature, dissolved oxygen, biochemical oxygen demand, hardness, alkalinity, phosphate, nitrate, total dissolved solids, total suspended solids, electrical conductivity, and transparency. The zooplankton was represented by 15% protozoa, 33% Rotifera, 46% Arthropoda and 6% Miscellaneous in the samples. The range of zooplankton recorded between 136 to 267no./l. The zooplankton density was minimum in January whereas the maximum was observed in October. This study may support to help towards the management of Hiran-II reservoir effectively in the region.
