Blue crab is a specialty of Zhejiang coastal area. How should this crab be raised?

Seeing a problem like crayfish, I came in. Actually, I have never raised a river crab. Personally, I feel that the life habits of river crabs are basically the same as crayfish. Eriocheir sinensis, also known as hairy crabs and crabs, has delicious meat and high nutritional value. Sometimes it moves underwater, and sometimes it goes ashore. It likes an environment with abundant dissolved oxygen and many aquatic plants. Therefore, various measures should be taken to create a good environment for Eriocheir sinensis to live in the pond in order to achieve the goal of high yield.

We often say that the scientific name of Eriocheir sinensis is Eriocheir sinensis. Eriocheir sinensis (Eriocheir sinensis) is an important species in freshwater culture, and it is also a crustacean aquatic product with more culture. Autumn and winter is a good time to eat crabs, when river crabs are the most plentiful. From the first fertilized egg to the larva, the big-eyed young crab, the young crab, the young crab, the yellow crab, the blue crab, the adult crab and the last parent crab. There are eight stages, which can actually be seen from a more scientific biological point of view. In order to ensure the elimination of diseases and the quality of fresh water and the flourishing growth of aquatic plants. The removed silt can't be left on the inner slope of the pond like fish farming, but should be transported out of the pond to prevent rainwater from rushing back to the pond, flooding the escape wall and causing turbidity in the pond.

Feeding palatable and high-quality feed: Eriocheir sinensis is an omnivorous aquatic animal with a wide variety of bait. At the initial stage of stocking crab species, nutrition must be strengthened to ensure smooth molting for the first time 1 time, which is conducive to improving the survival rate. Feed varieties mainly include small miscellaneous fish and clam meat. For river crabs, water seepage is not only the loss of pool water or the crab's escape along the waterway. Therefore, in the past, river crabs were raised in fish ponds. When cleaning the pond, it is necessary to deal with the water seepage in the place where the river crab escapes in time. A pair of appendages at the front end of the crab are called claw feet, and the surface is covered with fluff; There are 4 pairs of walking feet behind the claw feet, which are flat and long; Abdominal limbs have degenerated. The sex of a river crab can be distinguished by its abdomen: the abdomen of a female crab is round, and that of a male crab is triangular.

In the later stage, animal feed and crab pellet feed are mainly used, and green feed is properly matched to strengthen nutrition, so as to ensure that crabs can increase the nutritional requirements of the last 1 molting, so as to improve their individual specifications and yield.
