| Abstract: | This article reports that the larvae of Macrobrachium rosenbergii raised at the end of July. Which were cultured with fishes and had a culturing density of 25 individuals per square meter, after being cultured for 104 days. their output were 1528 kg Macrobrachium rosenbergii and 2661 kg fishes per hectar, The profit was RMB 31 315.5 per hectar, and the ratio of cost and yield is 1 : I. 82. The survival rate of Macrobrachium rosenbergii is 67.9% , the average weight is 9. lg per indi- vidual, and the largest male individual is 24g. the female 15. 8g. 85% of the Macrobrachium rosenbergii have the body length from 7cm to 9. 7cm. The authors also discussed the possibility of raising the weight and output of Macrobrachium |
