Generally, we can keep it in the refrigerator at home. First, we can find a box just big enough to put it in the refrigerator. Then we can tie up all the legs of the hairy crabs, put them in the box, cover them with a layer, cover them with a wet towel, and cover the foam box. This will ensure that the hairy crabs will not go bad for 3 to 5 days. When we want to eat them, we can just take them out. At this time, the hairy crabs are still alive, which can ensure the freshness of the hairy crabs to a certain extent.

2. Keep it in a basin or bucket

We need to find a plastic bucket of 30-50 cm, and the inner wall of the bucket needs to be smooth to prevent the hairy crabs from escaping. Pour water into it, and the water will overflow to half of the hairy crabs, which will ensure that the hairy crabs can breathe and reduce the consumption of physical strength, so that the storage time can be longer. Generally, it can be stored for more than 5 days when the temperature is not high.

3. Oxygen storage

In order to maintain the vigorous vitality of hairy crabs, we can put them in a deep bucket, put them in clean water, and use oxygen-increasing equipment to flush oxygen into them, which can also ensure that hairy crabs will not die, but when they are preserved, hairy crabs with poor vitality can be taken out to eat.

4, temporary storage pool preservation

If we buy too many hairy crabs at one time, we can't finish them in a few days. We can choose to use our own bathtub as a temporary breeding pool, put about half of the water into the hairy crabs, ensure that the hairy crabs can breathe, and feed a little fish and shrimp as needed. If this is preserved, it can generally last for more than a week.

5, cooked and preserved

Generally, if there is no proper way to preserve hairy crabs at home, we can wash them, steam them in a pot, wrap them with plastic wrap and store them in a refrigerator for about 3 days, but when we eat them, we need to cook them at a high temperature.
