Zooplanktons play an important role to transfer energy from the primary level to upper trophic organisms in aquatic bodies. Naturally, in rainy seasons, a number of rain-fed ponds have occurred for short existence. These seasonal rainy ponds are sustained for a maximum of two or three months before winter. In this short period, newly introduced rainfed ponds are known for the nourishment of zooplankton with temporal nutrients supplied from surface run-off and subsequently freshly flourishing algae. As in result, the fisheries could be enhanced and exploited as promising food sources to people through these seasonal rain-fed ponds. The present study is demonstrated with rotifer (10677.778 ± 2306.27 ind/l) followed by copepod (2184.72 ± 601.56 ind/l) and cladocera (884.72 ± 96.72 ind/l) with some aquatic chemical parameters such as dissolved oxygen (4.7-5.5 mg/l), ammonia (0.21-0.27 mg/l), nitrate (0.15-0.22 mg/l), total dissolved solids (245-508 mg/l) and pH (6.8-7.8).
