| 摘 要： | 在中华绒螯蟹的育苗过程中，采用添加微生物的方法调节育苗水体的水质，结果表明：与对照池相比，试验池中的氨氮明显下降，溶氧量增加，pH值变化不大；河蟹各期幼体的成活率提高，从SouⅠ期幼体至大眼幼体，试验池的成活率为13.9%，对照池仅8.1%。因此，在河蟹的育苗生产上，利用添加有益微生物的水质循环装置，能有效地提高育苗产量，节约成本。

| Abstract: | In the process of cultivating larvae of Chinese mitten crab ( Eriocheir sinensis), water quality was regulated by means of artificially adding microorganism. Results show that water quality of test group was better, NH 3-N was significantly lower and DO was higher than those of control group, pH value was almost the same. The survival rate of test group may reach 13.9% from the 1st zoea stage to megalopa, which was only 8.1% in control group. The output of cultivating larvae can be increased and cost can be reduced by artificially adding effective microorganism and water circulation device. |
