1. Put your crab in the bucket. First, take out the crabs that are eager to climb out of the bucket one by one and tie them tightly with rubber bands or ropes.
2. Adjust the temperature of the refrigerator to about five degrees above zero, take out the fresh-keeping box under the refrigerator, pour the towels that are not used at home into a transparent display and spread them below, then put the tied crabs on the display towels and put them in the refrigerator.
But it will take three or two days to see if it is foaming. At the same time, sprinkle some water properly and be careful not to put too much water. Because crabs can't move, they seldom consume nutrients in their bodies. After being taken out, it can still be used for steaming vegetables, and it needs to be checked frequently for deterioration.
Tie up the crabs and put them in the fresh-keeping layer of the refrigerator so that the hairy crabs can survive for 5-6 days.
The fresh-keeping time of hairy crabs can be prolonged by freezing, optimizing the placement mode and adjusting the water level. Put it on the fresh layer of the refrigerator and cover it with a wet towel. When eating every day, you can pick those who are not strong enough to eat first. Hairy crabs can be stored in plastic buckets, or they can be put in buckets, and they can't be stacked.
Add water until the hairy crabs are half as tall as their bodies. Secondly, hairy crabs that cannot be eaten must not be washed with water.
Because it is unlikely to be equipped with oxygen-increasing equipment, if the water is too deep, crabs will suffocate due to lack of oxygen.
Although the method is simple, it can make you buy crabs for a day or two longer than normal, and there is another advantage of this method, that is, salt water can make crabs spit out the dirty things in their stomachs. At the same time, you should also pay attention to the fact that no matter what method is adopted to prolong the life of crabs, the isolation between life and death must be ensured first.
The water depth should not be too deep for hairy crabs to stand and breathe on the water.
Store in a plastic bucket or jar. Prepare a plastic bucket/basin with a height of 30-50 cm and a smooth inner wall to prevent crabs from escaping. Put fresh crabs in, don't pile too much, or the crabs will die of lack of oxygen, and then add water, as long as it doesn't pass the crab claws, so as to keep moisture. Don't cover the container, check the crabs every day, and throw them away in time.
