2.Molting and growing.
Lobsters grow by molting, and the new shell hardens after 12-24 hours. Under the condition of water temperature 25 -30, rearing for 6-8 months, the weight can reach 60-150 grams. The general trend of lobster growth is:
From post-hatching to 20 g of body weight, the growth rate is an accelerated increase; At the stage of 50-100 grams, the growth rate remains at a relatively stable level, beyond which the growth rate tends to decline. As a result, an inverted U-shaped growth curve is formed. Molting is divided into two kinds: long molt and reproductive molting, after the juvenile shrimp is separated from the mother, it quickly enters the first molt, replaced with a soft and wrinkled new skin, and quickly absorbs water and grows, this is the growth molt, from the larvae to the adult body molt a total of 11 times.
Female shrimp begin to reproduce and molt after sexual maturity, and must perform reproductive molting before each mating and spawning in the future.

Lobsters can grow to be very large. And the lobster shell cannot grow with the lobster's body. Because of physiological needs, the lobster grows to a certain time.
A new layer of shell will grow under the already hardened shell. The new shell grows to a certain extent. Then the outer layer of the old shell that has hardened and cannot grow is removed.

Do crayfish also shed their shells? The owner filmed the whole process, and after crazy convulsions, he directly transformed gorgeously.

.Yes, you're smart, that's the truth.

1. The growth of crayfish is mainly completed by molting, and many molts will occur during the whole growth process from juvenile shrimp growth to adult shrimp.
2. Under suitable environmental conditions, the newly hatched juvenile shrimp has a short time interval of each molting, once in 1 2 days, and the time between molting is extended as the body grows.
3. During the molting period, the shrimp is most vulnerable to predators or the same kind of food, there is a fish called crab tiger, which eats crab and shrimp that have just been shelled.

Lobsters are crustaceans that grow by molting, and multiple molts occur throughout the growth process from juvenile to adult. Under suitable environmental conditions, the newly hatched juvenile shrimp have a short time between molting each time, once every 1 to 2 days, and the molting interval will be extended as the body grows. During the molting period, the shrimp is most susceptible to predators or the same kind of predators, and there is a fish called crab tiger, which eats crab and shrimp that have just finished their shells.
Lobster shelling 1 to 2 times a year in the artificial breeding pool, crayfish more than lobster shelling, usually a lobster weighing 20 grams of coarse and below the shell 2 times to 3 times a year, a weight of more than 30 grams per year 1 to 2 times, a weight of more than 30 grams per year 1 to 2 times, each shelling.

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 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<>
Black-shelled shrimp. Of course, it will be shelled, because our shrimp has bones on the outside of his body, and his bones will not change, so they can only be shelled according to the quarter of the year.
The main reason for insect shelling is the growth limitation and replacement of exoskeletons. >>>More
The lobster feeding method is as follows:1. Breeding facilities. Breeding lobsters should build ponds with flat bottoms, good water storage and sufficient water sources, with an area of 4-10 acres, and the water depth should be kept in the range of 1 meter to meters, and during the breeding period, plastic film should be used to build protective nets along the edge of the pond to avoid lobsters escaping. >>>More
Many people have heard that you can't eat fruit when you eat shrimp, and you can't eat vitamin C tablets when you eat seafood......Although the reason is not clear, everyone has heard a serious warning: such a combination will be poisonous! The theory is: >>>More
When the cicada is young, there is a relatively hard skin on the surface of the body, which prevents the outflow of substances in the body, and can prevent harmful substances from the outside world, which can protect the young cicadas. But when the cicada grows, it restricts its growth, so it has to be shedding its shell. to grow up. >>>More
