1, crab pond preparation, choose a place with many aquatic plants and good light, it is best not to shade by trees, and secondly, the water quality must be clean. Generally speaking, farmers choose the amount of three to eight acres, and then they can't dig too deep. One meter and two meters is enough for the crab pond, and then there must be a good drainage and irrigation system. Only with these can we ensure the normal growth of crabs.

2. The preparation of escape prevention measures requires a good drainage and irrigation system to ensure the normal growth of crabs. At the same time, attention should be paid to the silt in the pond, which should be hard, and other silt is not good. Those thick silt at the bottom of the pond cannot be left, so it must be dug clean. Nets should also be placed around the crab pond to prevent these crabs from accidentally escaping.

3. disinfection measures should be taken. These crab ponds should be disinfected every time before releasing crab seedlings, so as to avoid getting sick. The specific operation is to spray quicklime in the whole pool/0/5 days before stocking and disinfect the whole pool. It is generally 75 kilograms to spread evenly to an acre of land. Here, we choose to use quicklime, not only for disinfection, but also to add a lot of calcium ions to the water while reacting with water, which can provide more trace elements for crabs.
