Prepare a plastic basin or bucket and put the lively crabs in it. Be careful not to stack them on top of each other. Add water to half the height of the crab's body, pay attention to moisturizing, but you can't cover all the water, because the water is too deep, the crab will die of suffocation due to lack of oxygen, and the basin or bucket does not need to be covered. If the temperature is not very high, crabs can be preserved for more than half a month in this way.

2. Keep it in the bathtub:

If you can't eat all the crabs in three to five days, the best way to save them is to let them enjoy their own bathtub-a temporary breeding pool-because the walls of the bathtub are smooth and crabs can't escape. Gently pour the crab into the bathtub, fill it with water until it is just buried, let the crab breathe on the water, and put a small amount of small fish and shrimp according to the storage time and quantity. Generally, more than 7 crabs can be stored in Yangcheng Lake in this way.

3. Can hairy crabs still be eaten after they have just died? If you find that hairy crabs have been dead for more than two hours and smell fishy, don't eat them, because after the death of hairy crabs, the protein in the body will change and produce "crab yellow", which is easy to be poisoned after eating. It is best to wrap the unfinished hairy crabs in a wet towel and put them in the refrigerator for a week or so.

When hairy crabs are dying or dying, the rich nutrients such as protein and fat will become the nutrients of bacteria, leading to a large number of bacteria. At the same time, protein will be decomposed into cadaverine and histamine, which are toxic and can lead to poisoning, while histamine can cause allergies, such as numbness of limbs, skin allergy, general weakness, and even allergic phenomena such as asthma and dyspnea.
