Hairy crab is a very common and popular home-cooked dish, but its survival time is short, and it will not be fresh after a long time. The preservation time of hairy crabs can be prolonged by freezing, optimizing the placement mode and adjusting the water level.

1. Tie the hairy crab's feet to the gate.

2. Put it on the fresh-keeping layer of the refrigerator and cover it with a wet towel. When eating every day, you can pick the one with insufficient physical strength.

3. Hairy crabs can be stored in plastic buckets, and they can't be stacked.

4. Add water until the hairy crabs are half as high as their bodies. Secondly, hairy crabs that can't be eaten must not be washed with water.

Precautions:

1, because it is unlikely to be equipped with aerobic equipment, if the water is too deep, crabs will die of hypoxia and suffocation.

2. There is no need to cover the bucket/basin. Check the crabs every day, eat the crabs with insufficient vitality in time, and preserve the crabs in this way. When the temperature is not high, the hairy crabs can be preserved for more than 5 days.
