Crabs belong to crustaceans and reproduce by laying eggs.When the female crab reaches the age of sexual maturity, she will mate with the opposite sex and then lay eggs.Generally speaking, the time for crabs to lay eggs is from December to mid-March and early March of the next year, especially in spring when the temperature is more suitable, the phenomenon of crabs laying eggs is more common.
Every time the crabs lay eggs, they usually come up to the highlands. The number of eggs they lay is relatively large. Sometimes they can lay millions of eggs at a time.Although these eggs may not be able to hatch out and grow up, but those who can successfully hatch out or more.The growth of crabs needs to be carried out by shelling, and the next growth stage needs to be completed by shelling.
The number of times crabs reproduce is limited. Generally speaking, they can reproduce at most once a year. Sometimes, they do not even reproduce once a year. They may reproduce once every few years.For some crabs that live in the ocean, female crabs generally lay eggs once a year.However, for some river crabs living in fresh water, they usually lay eggs once a few years.The frequency of crab orchid production is also related to the surrounding environment.In a suitable environment and sufficient bait environment, the growth and development of crabs will be better, at this time they may lay eggs once a year.However, if the environment is not suitable, it may also affect their spawning.
Although the number of times crabs lay eggs is not much, but the number is very large, it can also be said that the reproductive efficiency of crabs is relatively high, reproductive capacity is relatively strong.
