1. Crab feeding management. River crabs like to eat fresh ingredients. For this reason, in daily feeding management, those feeds that have been stored for a long time and have deteriorated are prohibited. At this stage, it is still necessary to put mainly meat feed, with appropriate amounts of nutritious vegetarian food, especially more plant-based feed, to ensure good water quality in the pond. The frequency of use of materials should be determined according to changes in climate and temperature. In hot summer, feeding only 1 to 2 times is enough. The specific quantity depends on the weight of the river crab. If there are uneaten residues, they should be salvaged immediately to avoid deterioration and affecting water quality.

2. Crab breeding management, strengthen daily feeding management, and implement daily inspections. Inspect at least 1 to 2 times a day, once in the morning and once in the evening, and pay attention to the feeding situation of river crabs. When abnormal conditions occur, you should immediately check whether there is any disease, and actively use symptomatic medicine to avoid the spread of infectious diseases and affect the breeding efficiency. As the breeding population increases, hypoxia in the water body occurs from time to time. Water should be changed and oxygenated in a timely manner to reduce the high fatality rate caused by hypoxia. In addition, you should also check whether there are any loopholes in the pond and block them to prevent the invasion of natural enemies and avoid escape.

3. Disinfection management of crabs, remove pathogens and bacteria in the pond, and create a good breeding environment for healthy crab breeding. Before and after breeding, pond disinfection and management should be done well. Before young crabs enter the pond, they should be disinfected in advance and the silt in the pond should be cleaned in time in winter. During the breeding and management process, the disinfectants selected must have low toxicity and rapid volatility to avoid environmental damage caused by disinfection.
