3. Use ancient wells to preserve.

There are also that kind of stone-built ancient wells in the countryside, in which the water flow is relatively good, clean and cool, and there are a lot of small fish and shrimp for food, which is more suitable for preservation. You can use a large frame or net to pack the hairy crab and put it directly into the ancient well, not all of it into the water, otherwise the crab will suffocate due to lack of oxygen.

It is also a good way to put the crab in the fish tank, and there must be oxygen equipment in the fish tank. It is best to eat the crab as soon as possible, if the crab dies, don't eat it, the dead crab is poisonous.

Sea crab cryopreservation method:

Fresh sea crab cryopreservation: The sea crab's feet are tied with rope to prevent the sea crab from crawling around and increasing unnecessary physical exertion, and then a layer of ice is spread underneath to put the sea crab in the freezer.

You can also put fresh sea crabs directly into the freezer of the refrigerator, and the sea crabs can be stored in the freezer for about a week, and they can be thawed directly when eating.

At the temperature of the cold room, the crab will be in a state similar to dormancy, and in this case, it can last for several days without dying.

When we take the crab out and cook it again, we can still eat the crab very delicious.

Refrigerator preservation method.

The temperature of the refrigerator preservation layer is about 3-7 degrees, which can reduce the activity rate and metabolism of crabs, and the high humidity inside the refrigerator is conducive to the crabs to maintain the humidity of the body, and whether it is live or cooked crabs can be put into the refrigerator for preservation, which is the most convenient place to preserve crabs.

1. Preservation method of live crabs.

First of all, select the more vigorous crabs for retention, and then use a cotton rope to tie up the crab's feet and tongs, which can reduce the physical consumption of the crab, and then you can prepare a wet towel to cover the crab, and then put the sea crab into the refrigerator freezer to store or directly put the bundled crab into the freezer layer for preservation, generally refrigeration can be stored for about 2-3 days, and freezing can be stored for about 2 months.

2. Preservation method of boiled crabs.

Directly the cooked crabs, sealed in a crisper and then put in the refrigerator to refrigerate or freeze, generally refrigerated can be stored for about 2 days, and frozen can be stored for about a month, but the taste and nutrition of cooked crabs after freezing or refrigeration will be greatly reduced, it is recommended that if the cooked crabs can be eaten within 6 hours, they are generally eaten as soon as possible after being placed at room temperature.

Hydrotrophic conservation method.

By raising sea crabs in a bathtub or bucket of water to make them mistakenly think that they are still living in the water, you can store them for about 1 week in a short period of time.

Here's how. 1. Prepare a bathtub or bucket and other items, and require the items to be smooth around and above 50 cm in height to avoid sea crabs from crawling out and running away.

2. Then select the energetic live crabs, put them in the bathtub or bucket, and then add the seawater or light salt water that can not pass the sea crabs, usually the ratio of water to salt is 100:1.

3. In order to ensure that the sea crabs can survive normally in the bathtub and bucket, it is also necessary to do a good job of feeding, and put in an appropriate amount of bait 2-3 times a day according to the amount of sea crabs, usually fresh small fish and shrimp.

Note: The amount of water added should not be too high, so as not to prevent the crab from breathing, resulting in death, in addition, it is not necessary to ** under the crab is not dead, if it is dead, it is necessary to pick out the dead crab, so as not to produce germs and cause a large area of death.

Dead sea crabs do not need to be preserved and should be discarded.

Because once the sea crab dies, the body will not be able to excrete some microorganisms and animal carcasses that were eaten in the sea before, and it will also become the best food for bacteria because the sea crab is rich in protein, resulting in a large number of bacteria multiplying in a short period of time and breeding some biotoxins.

Hello! Sea crabs should be bought back; 1. If it is dead, throw it away immediately when you buy it. Freshly dead sea crabs are frozen in the refrigerator, and the lower the temperature, the longer the freezing time will be, and if it is minus 18 degrees, there will be no problem for one or two months.

2. If it is put live in a bucket, choose a vigorous crab, tie the crab's feet to reduce the physical exertion of the crab, and then cover it with a wet towel to preserve. Hope mine can help you! Have a happy life and good health!
