Before winter, the silt in the pool should be cleaned in time and disinfected. Try to control the water temperature above 10 degrees. If it is lower than 10 degree, the feeding amount will be reduced by 3-5%. Patrol 1-2 times a day, and take preventive measures in advance.

Second, how to raise it so as not to die?

1, feeding environment

At home, you can choose a relatively spacious pool with a certain depth to prevent crabs from escaping. It can be a cement pool or a larger plastic basin.

Spread a layer of silt about 10 cm and river sand about 5 cm in the culture pond. You can go to the river or lake to get some sand or buy it online

If you plan to keep crabs at home for a long time, you can also plant some aquatic plants that are easy to survive in the pool, such as black algae, Sophora alopecuroides and Elodea. It can not only purify the water quality, but also be used as bait for crabs.

The specific planting of several aquatic plants depends on the size of the farm and the number of crabs.

2, sand crab specifications

It is suggested that the specifications of crabs raised in the same pond should not be too different, so as not to affect the survival rate of crabs.

In addition, it is necessary to ensure that the crab itself is free from diseases and injuries.

3. Feeding management

(1) bait

In the process of feeding, you can feed red worms, shrimp, snails, mussels and other animal feeds, supplemented by aquatic plants, pumpkins, potatoes and other plant feeds, and feed them 1 time in the morning and evening, so that crabs will grow better.

(2) Change water

On the issue of changing water, it is suggested to change water once every three days. After changing the water, a proper amount of quicklime can be poured and disinfected in time.
