Generally, hairy crabs' physique will decline after high temperature in summer, and will face the last molting one month before listing. When the old shell and new shell have not hardened, they are vulnerable to parasitic infection of harmful bacteria. At this time, the biological disinfectant without stimulation of shrimp shell should be selected to control the number of harmful bacteria in the water to ensure the smooth molting of hairy crabs. In addition, the water temperature decreases gradually in autumn, and the crab pond should be kept at a depth of 1.2 meters and a transparency of 35 to 40 centimeters. In addition, vitamin C can be sprinkled, or microbial preparations can be tried every 10 days.

Autumn is the best time to increase the fatness and absolute weight of hairy crabs, so the proportion of concentrate feed should be increased, the protein content should be increased to about 32%, and the feed nutrition should be comprehensive. Pay attention to the addition of vitamins and minerals in feed. In addition, during the culture period, we should also pay attention to the appropriate and timely supplement of calcium for hairy crabs. The last molting cycle before fattening on the market is as long as 1 month. It is recommended to take about 1 week to supplement calcium regularly, such as lasting 3-4 weeks. It can improve the molting success rate and doubling rate of hairy crabs.
