Various zooplanktons are use as a food material for fish. Rotifer is among one such group of zooplanktons which is widely use as a live feed for culture of various fishes and other aquatic organisms. In the present study the culture of rotifers like Brachionus calyaflorus, Brachionus havanaensis, Brachionus plicatilis is carried out under the laboratory conditions for which healthy samples of zooplanktons were collected from the fresh water resource and separated for isolation of rotifers with the help of fine tipped micropipette. The isolated rotifers were transfer to the culture tank at the rate of 10-20 individuals/ml and feed upon algae (Chlorella, Scenedesmus) approximately at concentration 40�103 cells/ ml. Growth of rotifer culture slow for initial 2 day that is 170 individuals/liter and attain its peak density at 3rd and 4th day that is1050 individuals/liter and 2440 individuals/liter respectively. From 5th day rotifer population start to decrease which was found to be 1510 individuals/liter on 5th day, 960 individuals/liter on 6th day, 750 individuals/liter on seventh day and 300 individuals/liter at 8th day The harvested rotifers then proceed for drying to get powdered form which can be use as a fish feed.
