Crayfish can be washed and cooked according to your own taste, then poured into a plastic bag with the lobster soup, and placed in the refrigerator to defrost when ready to eat. Crayfish are quite aggressive, so if possible, use a large basin to allow space. At the same time, crayfish like dark and humid places. You can cover the pot with a black plastic bag or other things to allow them to sleep as peacefully as possible, reduce tension, and reduce the chance of a sword fight.

Because dead lobsters cannot be eaten, we have to buy live ones. You can seal it in the refrigerator and freeze it. The refrigerator has two layers: fresh-keeping and freezing. If you only need to store crayfish for about a day, you can put them in the fresh-keeping layer. If you want to preserve the crayfish for a long time, you can put them in the freezing layer. When they are alive, we put them in plastic bags and add water. Place directly into the refrigerator for quick freezing. Of course, if you feel that the overall shape of the crayfish is damaged, we can put a few bags on it to prevent it from breaking.

Due to its high protein content, crayfish produce cadaverine and histamine when broken down by bacteria, which are unhealthy for food users. Although freezing can reduce the growth rate of bacteria, some bacteria can still survive in the refrigerator, so it is not recommended to freeze crayfish for too long. About 20 days should be enough. Cooked crayfish can usually be eaten the same day. If you can't finish it, put it in the refrigerator. Live lobsters are not easy to preserve because there is no oxygen in the house, so we can cook them and put them in a cold refrigerator.

It can be stored for two or three days, which not only preserves the crayfish, but also allows the crayfish to spit out clean sediment. It can save a lot of trouble when cleaning the crayfish. You can also oxygenate the crayfish in the water or put the crayfish into the water. Put the lobster in the water pump tank and change the water once in the morning and evening. It can be stored for 5-10 days. Typically, crayfish are washed and placed in a metal bowl with just enough water to cover the shrimp. Then put it in the refrigerator, put the water and frozen shrimp together, take it out, leave it at room temperature for a period of time, take out the frozen shrimp, seal it with a plastic bag, and store it in the refrigerator.
