Hairy crabs still "molt slowly" after 24 hours of uninterrupted oxygen inhalation. Will Yangcheng Lake hairy crabs miss the Mid-Autumn Festival table?

Hairy crabs are an indispensable dish on the Mid-Autumn Festival table. However, under the influence of the continuous high temperature this year, hairy crabs grow very slowly, and it seems that they cannot occupy a place on the Mid-Autumn Festival table this year. What is the reason? Will Yangcheng Lake hairy crabs really miss the Mid-Autumn Festival?

The weather is abnormal this year. There is continuous drought in the Yangtze River basin, and the temperature in Suzhou is around 40 degrees for more than a month. Due to the high temperature, crabs in Yangcheng Lake shed their shells much more slowly than in previous years. In an interview with reporters, I learned that crabs need to shed their shells five times, and each time it takes a certain amount of time. It's September, and the hairy crabs have just finished molting for the fourth time. If the normal progress is followed, the crab will shed its shell for the fourth time and the fourth time. High temperature and high fever lead to microbial decomposition in the lake, and the oxygen content in the lake is seriously insufficient. Some crabs even die directly because of lack of oxygen when molting. This situation reminds many crab farmers of scratching their heads.

There are solutions, but the cost of raising crabs has increased a lot. In order to survive, many crab farmers put oxygen generators in the lake to provide oxygen for crabs. Vitamin C and probiotics are added to the oxygen machine to help crabs survive better. The cost is one day in 200 yuan, and these rising costs will also have an impact on the price of crabs this year.

Although you can't eat crabs in Mid-Autumn Festival, you can buy crabs. In order to get out of the crab dilemma, many e-commerce platforms have sold crab rolls in advance, and the price of crab rolls has increased by about 40% compared with previous years. Many netizens joked that they can buy crabs on Mid-Autumn Festival and eat crabs on National Day. Although it is a joke, it is also a fact. For farmers, there is no alternative but to wait quietly for crabs to shed their shells. It is also very hard for farmers to increase oxygen in the lake during the day and reduce the water temperature at night. This year's crabs really embarrassed a group of people!
