Careful friends may find that the abdomen of the hairy crab we buy is white, some are gray, and even some hairy crabs with gray abdomen cannot be brushed clean with a brush. There is no doubt that this is certainly not the hairy crab of Yangcheng Lake.
We know that the authentic Yangcheng Lake hairy crab has been famous for its four characteristics since ancient times: "blue back and white belly, golden claws and yellow hair". Authentic Yangcheng Lake hairy crab belly shell is generally milky white.
Although some crabs will have yellow belly stains that are stained with water stains in the lake, the brush can wash the stains attached to the shell with a brush, showing its clean abdomen, crystal white, shiny, and no ink spots.
So, why is the white belly of the hairy crab in Yangcheng Lake formed?
Hard lake bottom
The environment at the bottom of Yangcheng Lake is very special, it is a rare sandy soil, the texture is hard, and there is almost no silt. Hairy crabs living at the bottom of Yangcheng Lake rarely have access to silt, which reduces the possibility of being impregnated by silt.
Moreover, the sandy soil at the bottom of the lake has a certain polishing effect on the abdomen of the hairy crab crawling on the bottom of the lake, which can wipe off the dirt contaminated on the belly shell of the hairy crab and make the belly of the hairy crab smooth and clean.
Lush aquatic grass
Yangcheng Lake has a rich water grass, the hairy crabs that inhabit here like to climb with the help of aquatic grasses, often "playing" and "playing" on the aquatic grass, the body of the hairy crab rubs with the aquatic grass, and is constantly brushed by the aquatic grass, and the body becomes clean.
The clean and white belly makes the hairy crabs in Yangcheng Lake more recognizable, but sometimes they will be extremely counterproductive. If the belly of the hairy crab bought home is too white, it is an abnormal phenomenon.
Even if the water quality of Yangcheng Lake is good and the environment at the bottom of the lake is unique, it is inevitable that some scale will remain in the abdomen of hairy crabs. That is to say, if the abdomen of the hairy crab is too white, it means that the purchased hairy crab may not be produced from Yangcheng Lake, but from other lake basins. It is only caused by the artificial method of bleaching hairy crabs by farmers in other lakes in order to sell their own crabs at a higher price and at a faster rate.
Although the white belly is one of the criteria for judging whether it is an authentic Yangcheng Lake hairy crab, it cannot be limited to this when selecting hairy crabs, or it needs to be judged comprehensively through other aspects, and it cannot be confused by some counterfeit goods!
