In 1996, I rented 20 mu of fish ponds in the village to start raising crabs, and the benefits were better. In 2004 I expanded the scale of crabs, fish ponds area reached 730 mu. I bought 5,500 kg of crab from the South, and in order to understand the growth of the Japanese mitten crab in our area, I bought another 800 kg of Suifenhe crab in the pool for about 150 days.
