In the case of reasonable preservation, put some water to keep humidity, crabs can survive for about 10 days. Crabs are very picky about their living environment, and they can't be too dry or too wet.

How to raise crabs in water

1, put water in the bathtub to keep you alive

If you buy too many hairy crabs, you can feed them in the bathtub. The bathtub is smooth around, which can ensure that hairy crabs will not escape from prison. Put a proper amount of water (only 1~3cm thick) in the bathtub to ensure the humidity of hairy crabs, and then put some small fish, loach and live shrimp as their food, which can be stored for 5~ 10 days and can be caught and eaten at any time.

2. Plastic buckets/cans should be kept alive with water.

Prepare a plastic bucket/basin with a height of 30-50 cm. The inner wall of the plastic bucket/basin is smooth and difficult to get rid of. Put the hairy crabs in, don't stack them; Then add water to half the height of the hairy crabs and keep them moist. Don't bury the hairy crabs. If the water is too deep, crabs will suffocate due to lack of oxygen. Don't cover the bucket/basin, check the hairy crabs every day, and eat the hairy crabs with insufficient vitality in time, so as to preserve the hairy crabs. When the temperature is not high, hairy crabs can be kept fresh for more than 5 days.

It is suggested that the crab's feet can be tied, which can reduce the physical consumption of the crab and the crab itself is not so easy to die. Also, if hairy crabs are too thin or want to be stored, you can feed sesame seeds or broken eggs and add some yellow wine to fatten them up.
