%X The density of rotifer Brachionus calyciflorus and the changes of environmental conditions were studied in aquarium,in which both rotifer and fish( Tilapia nilotica and Misgurnus anguillicaudatu) separated from each other were grown in medium of algae in outdoor.Results show that density of rotifer cultured with Misgurnus anguillicaudatus excesses 100 individual per ml in 11 days.There are 5 days in which rotifer densities attain 200 ind./ ml and the highest density attain 250 individual per ml.The time in which rotifer densities excesses 100 individual per ml is 6 days in aquarium cultured with Tilapia nilotica. In contrast,the density of rotifer is lower than that cultured with fish,and lasting time is shorter than that in aquarium with fish.The highest density of rotifer is under 100 ind./ml.The authors suggest that the lasting time of higher density of rotifer could be prolonged when it cultured with fishes.
