摘要
分别于 1997年 3～ 4月和 1998年 4～ 5月在浙江舟山、鄞县两地河蟹土池育苗中进行了一种阶段性养水给饵技术的试验。主要技术措施包括孵幼前的施肥养水、幼体培育中丰年虫无节幼体的间断性停喂和后期外源性天然饵料的利用。结果表明，该技术不仅可以减少饵料及亲蟹成本，而且可明显提高一期蚤幼的变态率，稳定土池育苗的产量。
The tests of intermittent fertilizing and feeding in artificial breeding of Mitten crab are carried out respectively in earthen ponds of Zhoushan and Yinxian. The main technical measures include fertilizing bebofe hatching of crab eggs, intermittent feeding during cultivation of the larvae and utilization of exogenous natural food. The results indicate that the technique could not only reduce the cost of food and parent crab, but also increase evidently the metamorphism ratio of Z1 and stabilize the output of crab seedling.
