At that time, there were dense river networks in the south of China, and for a long time, the output of hairy crabs was very large. However, with the increase of human activities, especially the prevalence of a large number of reclamation activities around lakes, coupled with a large number of chemical pollution, the number of wild hairy crabs has dropped sharply. When the number of wild hairy crabs plummeted, the cultured hairy crabs did not catch up, and the final result was that hairy crabs were expensive in Luoyang for a time. However, the artificial breeding of hairy crabs has now entered a comprehensive scale. Under such circumstances, it is normal for the price of hairy crabs to fall.
Yangcheng Lake is no longer the only lake. Speaking of hairy crabs, almost everyone will mention Yangcheng Lake. It was true that the hairy crabs in Yangcheng Lake were famous for a while. However, with the excessive reproduction of Yangcheng Lake hairy crabs, many foreign crabs were sent to Yangcheng Lake for swimming in order to sell at a high price, which caused a strange phenomenon of hairy crabs. If there is no name of Yangcheng Lake, the price of hairy crabs is particularly low. If there is a name of Yangcheng Lake, the value of hairy crabs will double immediately.
But in recent years, with the gradual escalation of consumer news, people are no longer so superstitious about whether hairy crabs belong to Yangcheng Lake. In Hangzhou, the sales of Taihu hairy crabs produced locally in Hangzhou account for 72% of the total sales in China. Another example is Wuhan. The hairy crabs in Liangzi Lake around Wuhan account for 6 1% of the total hairy crab orders. It can be said that local hairy crabs have gradually occupied the theme, so the price of Yangcheng Lake has gradually returned to normal.
