1. Pond building and equipment: carry out appropriate pond reconstruction at the selected location. Clean the bottom of the pool, remove sediments, weeds and mud at the bottom of the pool. Then build dikes and water retaining facilities according to the actual situation to ensure that the water in the pool does not leak. Finally, install equipment and facilities, such as pumps, filters, feeders, etc.

2. Feeding management: Chili crabs are omnivorous animals, and their feed should be mainly granular feed with high protein, high energy and high nutrition, with a certain proportion of animal feed such as fish, shrimp and shellfish. According to the growth of crabs, the amount of feed should be appropriately increased or decreased to avoid feed waste and pollution.

3. Disease prevention and control: Pepper crabs may be affected by some common diseases and parasites in the breeding process. Therefore, it is necessary to observe the state of crabs regularly, and once abnormalities are found, measures should be taken to prevent and control them in time. In addition, although Chili crabs can survive in the water depth of 40 cm, the more suitable water depth is 12~ 14 cm. This is because Chili crabs can't be cultured in deep water. Too deep water will affect their activities and even lead to their poor growth and development. At the same time, in order to make the Chili crab climb out of the water easily, the culture pond should be covered with a layer of sediment, and the sink should be prepared for it to climb.
