笔者于 1998～ 2000年连续三年对河蟹生态育苗进行了初步试验，于 1999年初次育出大眼幼体。 2000年进一步试验，产量最高的池塘生产蟹苗 3.8公斤 /亩。总结三年来的实践，笔者认为若能抓住育苗过程中的关键技术，即可获得比较稳定的产量。 一、材料与方法 共三口育苗
In 1998 and 2000 for three consecutive years, I carried out preliminary tests on ecological breeding of crabs and eared larvae for the first time in 1999. Further tests in 2000, the highest yield of ponds to produce crabs 3.8 kg / mu. Summing up the practice in the past three years, I believe that if we can seize the key technologies in the breeding process, we can get a more stable output. First, materials and methods A total of three nursery
