This research compares the effects of different organic manures on zooplankton production in culture systems. The manures used were Poultry droppings, Cow dung, Cassava peels and a Control (without manure) and were added into the culture systems at the rate of 57 mg dm-3 of water. The research was carried out for a period of twelve weeks after then identification and counting of species of zooplankton was done by taking 1ml/day from culture systems and water quality parameters in each culture system was also determined once daily. Zooplankton observed were Filinia sp. and Brachionus sp. belonging to Rotifera, Moina sp. and Daphnia sp. belonging to Cladocera and Cyclopods belonging to Copepoda. Moina sp. accounted for 11751 out of the total abundance of zooplankton irrespective of culture system while Daphnia sp. accounted for 11683, Cyclopods 7332, Filinia sp. 5594 and the least was Brachionus sp. accounting for 5230 total zooplankton.
