3. What are the autumn fattening methods for Chinese mitten crabs?

To obtain high benefits from Chinese mitten crab farming, under good market conditions, the fatter the crab, the higher the selling price, and the better the benefits obtained. Therefore, fattening is crucial in Chinese mitten crab farming.

1. Water quality environment for Chinese mitten crab farming

Generally, after the high temperatures of summer, the physique of Chinese mitten crabs declines somewhat. One month before market season, they will face their last molting. When the old shell has just been shed and the new shell has not yet hardened, they are relatively fragile and susceptible to parasitic infection by harmful bacteria. At this time, biological disinfectants that do not irritate the shrimp shell should be chosen to control the number of harmful bacteria in the water body and ensure that the Chinese mitten crabs molt smoothly. In addition, as autumn water temperatures gradually decrease, the crab pond should maintain a water depth of 1.2 m and a transparency of 35-40 cm. In addition, vitamin C can also be sprinkled in, or a microbial preparation can be used once every 10 days.

2. Chinese mitten crabs should be fed scientifically

Autumn is the best period for increasing the plumpness and absolute weight of Chinese mitten crabs, so the proportion of concentrated feed in the feed should be increased, the protein content needs to be increased to about 32%, and the feed is required to be comprehensive in nutrition. Pay attention to the addition of vitamins and minerals in the feed. In addition, during the farming period, attention should also be paid to appropriately and timely supplementing calcium for Chinese mitten crabs. The last molting cycle before market fattening lasts as long as 1 month. It is recommended to use about 1 week to regularly supplement calcium. If continued for 3-4 weeks, the molting success rate and doubling rate of Chinese mitten crabs can be improved.

3. Epidemic disease prevention and control in Chinese mitten crab farming should be strengthened

For the prevention and treatment of diseases in Chinese mitten crabs, a preventive method combining oral and external medicines can be used. Add oral medicines to the compound feed and feed them, and persist in mixing biological preparations into the feed for feeding. The preventive effect is relatively good. Each month, hamburger garlic granules and the like can be added to the feed and mixed in for feeding for 3-5 consecutive days, so that the Chinese mitten crabs grow healthily. In addition, the living site should be disinfected every 10-15 days.
