The shell of the crayfish can protect itself from predators, because the shell of the crayfish is very hard, rats and snakes are very fond of eating crayfish, and this hard shell can protect the crayfish well.
The shell of the crayfish can also prevent the invasion of viruses and germs, once the shell of the crayfish is broken, then the crayfish is very easy to be invaded by germs in the external environment, and finally lead to the death of the crayfish.
If the crayfish is still a young and the shell is broken, then the crayfish will definitely die. Because the resistance and vitality of the crayfish in the seedling stage are weak, the germs are also the most susceptible, if the shell of the crayfish is broken in winter, then the crayfish will basically die. Because of the low temperature in winter, crayfish hide in their holes for the winter, and if the shell is broken at this time, it will inevitably cause the crayfish to move slowly and be easily frozen to death.
In the hottest part of summer (when the temperature reaches 35 or more), if the shell of the crayfish is broken at this time, then the possibility of the crayfish dying will be higher. Because the higher the temperature, the more active the germs, and the crayfish are also very easy to die from bacterial infection.

The growth rate of crayfish is very fast, from the seedling stage to the commercial shrimp only about three months.
Crayfish need to molt five or six times, usually once every half a month.

Summary. Hello dear, I've been waiting for a long time, as far as I know, lobsters that can't get out of their shells can be eaten. But try to eat as little as possible.
The reasons for not shelling are as follows:
First, the reason for shrimp seedlings.
For example, the use of inbred shrimp seedlings, weak constitution, congenital insufficiency, low immunity, easy to get sick.
Second, the reason for the lack of aquatic plants.
The lack of grass in the pond for crayfish to shelter and hide often causes crayfish not to molt or delay molting, which is very detrimental to growth. Suggestion: For aquatic plants that do not grow vigorously, top dressing in time, and replant in time where there is no grass and little grass.
Third, the water quality is not good.
The dissolved oxygen in the water is seriously insufficient, and the demand for dissolved oxygen in the water is higher when the crayfish molt, and if the dissolved oxygen in the water is less than 3 grams, the crayfish will have difficulty molting.
Can you eat lobsters that can't get out of their shells.
Hello, your question has been received <>
Answer: Xiao Yue'er is sorting out the answers to the questions, please wait a while<>
Hello dear, I've been waiting for a long time, as far as I know, lobsters that can't get out of their shells can be eaten. But try to eat as little as possible. The reasons for not shelling are as follows:
1. The reason for shrimp seedlings is that they use inbred shrimp seedlings, which have weak physique, congenital insufficiency, low immunity, and are prone to disease. Second, the reason for the lack of aquatic weeds in the pond is that the crayfish rely on to shelter the hidden grass, often the closed hands of the crayfish do not molt or delay the molting, which is very unfavorable to growth. Recommendations:
For aquatic weeds that do not grow vigorously, top dressing in time, and replanting in time where there is no grass and little grass. Third, the water quality is not good, the dissolved oxygen in the water is seriously insufficient, the demand for dissolved oxygen in the water is higher when the crayfish molt, if the dissolved oxygen in the water is less than 3 grams, the crayfish will have difficulty molting.
1.Try to buy lobsters in the big vegetable market, and the lobsters in the big vegetable market are easy to peel off. 2.
Try not to eat the shell when eating lobster. The main components in the lobster shell are protein, chitin, minerals, etc., which do not contain toxic substances. However, because the texture of the lobster shell is relatively hard, it is difficult to chew, and it will cause a large burden on the stomach and intestines after eating, so the lobster shell is generally not eaten, so as not to cause abdominal pain, bloating and other indigestion symptoms after eating.
In addition, I usually like to eat crayfish, and when I choose, I want to pick the wild and choose blindly: red: The red little staring pure lobster is older, but the taste and emptiness are better.
Vitality: Energetic crayfish will open their tails, and the more energetic the crayfish is, the better the quality.
The above is my advice, you can take a look, I hope mine is helpful to you<>

Summary. We are happy to answer for you, larval stage: generally every 2-4 days to molt 1 shell, larvae after 3 molts will enter the juvenile shrimp stage.
Juvenile shrimp stage: generally molt once every 5-8 days. Adult shrimp:
Generally, the shell is molted once every 8-15 days. Crayfish generally need to molt 11-12 times from larvae to commercial shrimp, molting is an important sign that it begins to grow and develop, usually every molt it will grow a little bigger, and the new body after molting will harden after 12-24 hours.

Crayfish has a wide range of adaptability, has a wide range of suitable growth temperatures, and can grow and develop normally when the water temperature is 10-30. It can also withstand high temperatures and severe cold, can withstand high temperatures above 40, and can also survive the winter safely when the temperature is below -14. Crayfish grow rapidly, in the case of suitable temperature and sufficient bait, after more than 2 months of breeding, you can reach sexual maturity and reach the specifications of commercial shrimp, generally male shrimp grow faster than female shrimp, and the size of commercial shrimp is larger than that of female shrimp. >>>More
Crayfish is an invasive alien species, the origin is the United States, and later the United States was introduced to Japan to make feed for bullfrogs, and then introduced to Nanjing, China, to make scavenger fish and shrimp for water quality improvement. This statement should be arguably the most authoritative statement on the origin and origin of crayfish at present. >>>More
You can go to a formal school to learn food, and the taste is more authentic.
Try not to eat pumpkin after eating crayfish, because it is easy to cause dysentery after eating, and you can not eat it with papaya, so that it is easy to cause food poisoning, and black chicken is also like this, and then there is yam can not be eaten together, it is easy to cause abdominal pain, nausea, vomiting and other phenomena, in short, you must understand clearly when eating food, do not match it at will.

The first step is soaking. Some people buy crayfish and start washing them directly, and then start cooking them after washing them. In fact, this is not right, crayfish, like flower nails and snails, have a lot of sand and mud in their bodies, because they all grow in muddy water. >>>More
