| Abstract: | This article reports that the juveniles of Macrobrachium rosenbergii have the body length from 1. 0cm to 2.0cm after nursery cultivation in net -cages for 3 to 25 days,which were cultured with fishes and had a culturing density of 113 500 individuals per hectare,after being cultured for 120 days,their output were 1 532. 3Kg Macrobrachium rosenbergii and 1152. 0Kg Silver carps per hectare. The profit was 43 059. 0RMB yan per hectare,and the ration of cost and yield is 1:1. 79. The feed/ gain ration of Macrobrachium rosenbergii is 2. 12, the average survival rate is 75. 3%,the avevage weight is 18,4g per individual. |
