What's wrong with lobster shelling? How long will the shell be hard after shelling?

Lobster is a crustacean, which grows by molting, and molting will occur many times in the whole growth process from young shrimp to adult shrimp. Lobsters in farmed ponds are shelled 1-3 times a year, and crayfish are shelled more often than lobsters. Lobsters weighing less than 20g are usually shelled 2-3 times a year. Lobster can still move normally after drying in the shade 12-24 hours, and can stop temporarily when the shelling is disturbed.

First, what is the shelling of lobster?

1. Lobster is a crustacean, which grows mainly by molting. During the period from the growth of young shrimp to adult shrimp, lobsters have to shed their skins several times. Generally speaking, under suitable environmental conditions, the molting interval of newly hatched young shrimp is short, about 1-2 days, 1 time, and with the growth of the body, the molting interval will be extended. During molting, lobsters are easily attacked by enemies or the same kind. There is a kind of fish called crab tiger, which specializes in eating crabs and shrimps that have just molted.

2. Lobsters are shelled 1-3 times a year in artificial culture ponds, and crayfish shell more times than lobsters. Usually, lobsters weighing less than 20g are shelled 2-3 times a year, and lobsters weighing more than 30g are shelled 1-2 times a year. The individual weight will increase by 50%-80% every shelling cycle. Chemical and physical methods can be used to stimulate lobsters, and a variety of baits can be used to feed them in turn, which can promote lobster shelling to some extent.

3. Lobster can still move normally after drying in the shade 12-24 hours, and can stop temporarily when its shelling is disturbed. If the appendages and tail fans are partially or completely broken, they can be recovered by shelling, which will have any effect on growth. It is necessary to master the ecological characteristics of lobster, shorten the shelling period, stimulate the shelling times, improve the survival rate and increase the lobster breeding yield.

Second, how long will the lobster shell be hard after shelling?

1. The new shell of lobster after molting will become hard after 12-24 hours. Molting is mainly divided into long molting and reproductive molting. After leaving the mother's body, the young shrimp will quickly enter 1 molt, put on a soft new shell, and its water absorption will increase rapidly. This is growth molting, and the total molting times from larvae to adults are 1 1 times. Female shrimp will begin to reproduce and molt after sexual maturity, and then reproduce and molt before each mating and spawning.

Lobsters must be prepared before molting. As long as you are prepared, lobsters can molt normally. There are a lot of preparatory work in the early stage, such as water quality assurance, planting aquatic plants and weeds, disinfection of tangkou, elimination of natural enemies and so on. Good water quality can provide a better growth environment for lobsters, and good aquatic plants can provide some bait and safe molting space for lobsters. These are all places that need attention.

3. Pay attention to the feeding of the bait after the lobster enters the pool. Calcium can be properly supplemented during molting, and snails and other bait with high calcium content can be provided in the bait. When feeding, it must be well matched, whether it is plant bait or animal bait, it must be comprehensive, otherwise it will cause nutritional imbalance.
