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

2. put it in a basin or bucket

We need to find a 30-50 cm plastic bucket, 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, so as to ensure that the hairy crabs can breathe and reduce the consumption of physical strength, which can last longer. Generally, it can be stored for more than 5 days at low temperature.

3. Oxygen storage

In order to maintain the vigorous vitality of hairy crabs, we can put them in deep barrels, 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 we can take out hairy crabs with poor vitality when preserving them.

4, temporary storage pool to save

If you buy too many hairy crabs at one time, you 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 some fish and shrimp as needed. If you keep it like this, 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 in plastic wrap and store them in the refrigerator for about 3 days, but they need to be cooked at high temperature when eating.
