1, refrigerator refrigeration

If you buy a small number of crabs, you can eat them in about three days, so it is relatively simple to raise them. Choose vigorous crabs, tie their feet, put them in a box without a cover, then put them in the freezer of the refrigerator, keep the temperature at 5- 10, cover them with a wet towel and keep them for 2-3 days.

Step 2 keep it in a basin

Prepare a pot 30-50 cm high (a bucket is also acceptable), put the crabs in it, put wet aquatic plants and soft vegetable leaves on it, cover the crabs with aquatic plants, and then add water to half the height of the crabs, mainly to keep them moist so as not to bury them all. In this way, crabs can be kept fresh for more than 5 days at low temperature.

3, oxygen preservation

Put the hairy crabs into a deep bucket, then put them into clean water, then turn on the oxygen-increasing equipment and fill the water with oxygen to ensure that the hairy crabs can absorb enough oxygen and prevent them from dying from lack of oxygen. However, during the storage period, it should be checked every day, and the hairy crabs with insufficient vitality should be taken out and eaten in time.
