成蟹的起捕根据养殖方式的不同，可采取不同的方法。池塘养蟹的最好方法是排水捕捞法，就是把池里的水排放完，成区就会随着水流，汇集在预先挖设好的担槽里，再用手抄网捕捞。如果一次汇集不完，可以再注入新水，形成水流，让蟹重新汇集，再次捕捞。也可以在排水口上边挂上灯 Crab catching according to the different breeding methods can take a different approach. The best way to raise crabs in ponds is by the method of draining and fishing. That is to say, the water in the ponds is completely drained. As a result, water will be collected in the pre-dug tunnels and then be used to catch by hand netting. If you do not have a complete collection, you can inject new water into the water to re-assemble the crabs and catch them again. You can also hang the lights on the drain
