When is the flying crab the fattest?
The fattest season for crabs is generally September 9- 10/0 in autumn, which is true for most crabs, and flying crabs are no exception. Generally speaking, flying crabs are from south to north, and the peak season is from March to May and 9- 10, and the harvest time should be at the end of autumn. When the water temperature drops below 15℃ and the flying crabs no longer gain weight, they should be harvested in time. Most of them are around 65438+ 10 month, and the latest in southern China is 65438+February. The output of Liaodong Peninsula in Bohai Bay is relatively high from April to May.
Breeding season of flying crabs
The mating season is April-May to early winter in the Yellow Sea and Bohai Sea, and March-April to11~ 65438+February in the coastal areas of Fujian. In addition to sexually mature individuals, immature females can sometimes accept mating. From April to May every year, female crabs migrate and gather in coastal shallow harbors or near estuaries to breed, and the fertilized eggs laid are held on the abdominal limbs of the abdomen. Each female crab can lay two or three eggs in the breeding season, totaling several hundred thousand to two million eggs. Newborn eggs are yellow and turn dark brown after about two weeks. It hatches into a pod-like larva and lives a floating life with a cycle of ***5. In the fifth stage, after molting, it enters the big-eyed larva stage, and becomes a young crab after molting 1 time, from small to about 20 times. The average life span is about 3 years.
Flying crabs are fat in any way.
Whether the female flying crab is fat or not can actually be distinguished from its shell. First, turn the female flying crab upside down so that its white belly is up, and then observe the colors at the two sharp corners of the shell cover. If the female flying crab is all yellow, the color at the sharp corner should be red. If the female flying crab is empty and not so yellow, the color at the sharp corner is bluish white from the outside. ?
Compared with female flying crabs, it is more difficult to identify the quality of male flying crabs. Mr. Hao said that people who deal with seafood every day like them mainly rely on touch when identifying male flying crabs. Ordinary consumers may not be able to practice their touch in a short time. The easiest way is to look at the shell. The harder the crab shell, the better the quality of flying crabs.
