1, stored in the fresh-keeping room of the refrigerator.
When buying hairy crabs, merchants usually tie the crab legs with ropes, so we don't have to untie them when we get home. Putting them in the refrigerator directly can also avoid the crab's struggle and reduce the crab's physical consumption. After putting the crab in the refrigerator, we can just put a wet towel on the crab. This method can be kept within 3 days, so eat the less lively ones first.
2, put it in a basin to save.
Prepare a slightly higher and larger basin to prevent hairy crabs from running out. Put the hairy crabs flat in it, and be careful not to stack them. Then start adding water into it. The amount of water is about half of the crab's height. Don't put too much water, otherwise the crab can't breathe and die soon. Then just put the basin in a ventilated and cool place and keep it. This method has been relatively new for 5 days.
3. Keep it in the bathtub
I think this is the best way. If the bathtub at home is not used, crabs can be kept in it temporarily. Put all the crabs in, and then add some water. The amount of water should not be too much, which is similar to the above method. If possible, we can also add some small fish and shrimp to it. In this way, you can go to see it every day and eat the stale crabs as soon as possible. This method can probably be preserved for about 1 week.
