2 How can live crayfish live for several days? According to different preservation methods, the specific time of preservation varies, and the analysis is as follows:

1, refrigerator storage: 1-2 days, pour all the crayfish into the basin, add a proper amount of clear water and a small amount of ice cubes, cover the basin with a breathable rag to ensure air circulation and avoid odor, and finally put it in the freezer for storage. The temperature of the freezer is about 1-2 degrees, which can be passed in a low temperature environment.

2, room temperature preservation: 2-3 days crayfish in a big pot, put water and a small amount of ice in the big pot, the amount of water should not be too much, not over the head of crayfish, the water depth is about 2-4 cm, put it in the shade to avoid the sun, you can also use a black plastic bag or something to cover it on the pot, creating a dark and humid environment, allowing crayfish to relax and sleep, and reduce activities during the period, you can add. Food such as green leaves, steamed bread and diced meat can be kept for 2-3 days, or even longer. However, lobsters that are kept for a long time will lose weight, the meat will lose weight and the taste will be greatly reduced. It is recommended to eat them within 3 days.

3 How to store the washed crayfish until the next day? Frozen or refrigerated. The washed crayfish can be stored in the refrigerator. If it is eaten the next day, it can be frozen or refrigerated.

Generally speaking, it is best to eat crayfish on the same day after cleaning, and don't store them overnight, because most of the crayfish after cleaning are dead, and overnight storage will breed bacteria and microorganisms to a greater or lesser extent.

However, if it cannot be eaten in time, the washed crayfish can be stored in the refrigerator at low temperature, which can well inhibit the growth of bacteria and microorganisms, thus prolonging its shelf life. Generally, it can be stored in sealed refrigeration for about 1 day, and it can be stored in sealed refrigeration for about 1 month.

Pay attention to store it as soon as possible if you don't eat it, and don't store it in the refrigerator after washing it for a long time, which is prone to deterioration.

4 crayfish can be eaten without going to the shrimp line? Yes, but eating too much is not recommended.

Shrimp line is only the digestive system of shrimp, which contains things that the shrimp body has not digested and absorbed. Generally, lobsters are all cooked at high temperature, which can kill germs in the whole cooking process. Generally speaking, crayfish without shrimp line has no impact on health, but it is not advisable to eat more, because some food residues in shrimp line can promote gastrointestinal motility, and excessive consumption can cause diarrhea symptoms.
