This year, the Mid -Autumn Festival is advanced to September 10th. Compared with the mature fishing period in mid -to -late September of the year, hairy crabs are generally not "shelling". Therefore, the consumption scene of wine holding the lunar moon will probably be missed perfectly. Some people in the industry predict that due to the rare high temperature in Jiangsu and Zhejiang this year, the crab breeding industry will bring a real "baking". At the same time, the great increase in breeding costs has also made this year's embarrassing situation of high -quality crabs facing high price.

The water surface temperature exceeds 35 ℃

Hairy crab starts high temperature mode

This summer, high temperatures in many places across the country have broken through the historical record. Recently, the temperature of the main producing areas of hairy crabs has continued to be as high as 39 ° C in the temperature of Suzhou, Wuxi, Gaoyou, and Xinghua. It is undoubtedly a severe test of life and death.

The hairy crabs cultivated in the lake have extremely high requirements for the natural environment of the waters, but on the one hand, the high temperature weather has evaporated the water in the lake quickly, resulting in severe hypoxia in hairy crabs. On the other hand The nutritional "state can easily affect the growth of water plants and cause the food chain shortage of hairy crabs.

"During the shelling process of hairy crabs this year, there was a much higher mortality rate than previous years, so when hairy crabs were listed in late September, high -quality good crabs must face the situation of rising prices." The crab farmers of the crab farmers have been engaged in crab breeding for decades. She said that this year's hairy crab breeding is a particularly difficult year. From the weather conditions, every day the air is burning like a fireball, the hot and hot air outdoors is suffocating. Under such high temperatures, it is extremely hard to pull grass, change the bottom, feed, and oxygen to work under the scorching sun, so the cost of hiring artificially increased by 20%.

It is understood that the crab farmers in Jiangsu area are guarded in a simple shed built next to the crab pond day and night. Check whether the crab is ashore due to hypoxia at any time. Nothing to sleep. Another crab farmer Jiang Yun told the Beijing Youth Daily that the standardized farming pond water levels were about 80 cm to 1 meter. Because of the recent high temperature, pond water was exposed to the sun. Once the water temperature exceeded 35 ° C, hairy crabs began to stop eating. Therefore, one of the best remedies is to increase the water level, and the other is to improve the bottom of the pond to prevent pollution such as excreta and hydrogen sulfide of the crab.

Zhu Yanyu said that he currently has more than 200 acres of hairy crabs, of which 100 acres are pond crabs. If you do not take corresponding emergency measures, it is likely to cause large -scale death in hairy crabs. "For shallow water, if some crabs are not physically good, we must die. So we continue to oxygen water in the pond these days. Otherwise, the temperature will be higher and higher as the temperature of boiling water."

"The power consumption cost for oxygen in the lake this year has also reached a record high. If not oxygen, crab can't stand it." Zhu Yanzhen introduced, "Our master has more than 20 years of experience, they endure high temperature and heat, and give the lake at any time. At the same time, it is necessary to remove the mud or replace the mud of the river, so that the aquatic plants can be better, so that the hairy crabs hiding in the water grass are avoided by high temperature and heat. "

High -quality hairy crabs this year

Price may rise

Hairy crabs have to go through the shell 5 times in their lifetime, and every time they are molting, the crabs will grow up. Every year in mid -August, the last period of the hairy crabs began to mourn. Only by successfully completing this molting, can it be considered crab. The crab farmers who have worked hard for a year can finally gain a lot of crabs. It depends on this time.

The continuous high temperature also made Charian Chengdong Lake breeding households Xia Gennan also faintly worried. The high -temperature weather was too lazy to move, and the hot crabs were rare. Many crab farmers were worried about hairy crabs to molt the shell, and adults would be smaller than last year. According to his experience, it should be said that the mother crabs should have been molting one after another at this time. The male crab will be 15-20 days later. be lazy.

In addition, under the high temperature of this year, hairy crabs have signs of delay in molting. Lao Xia said: "The crab shell is late this year, and the crab shells have not completely hardened during the Mid -Autumn Festival.

What changes will it bring to the price of hairy crabs this year? Several crab farmers said that the cost of breeding rises is obvious to all, and the difficulty of breeding is much greater than in previous years. In addition, in addition to the high temperature affecting the production of crabs, some of the southern production areas returned to plowing this year, the production of crab production has decreased accordingly, and the cost of breeding and feed is also rising. "Several farmers said that hairy crabs are currently in the fifth molting period, and it is not good to expected the final listing price." If the weather is quickly alleviated, it will be better, but the price of high -quality hairy crabs has increased at least 20%. "

Yangcheng Lake has not been arrested yet

The crab card has been on sale

According to the practice of Yangcheng Lake Hairy Crab Association, one day will be selected in late September, and the uniform time will start fishing to ensure that Yangcheng Lake hairy crabs are arrested and listed on the same day. It has not been announced this year's starting date.

Although the crab is still tender, the crab card sales battle has been launched online and offline. Reporters from Beiqing Daily recently visited Sam, Carrefour, BHG and other supermarkets that hairy crab card coupons have begun pre -sale.

Although the showcase is empty and there is no crab, the crab cards at various prices in the store have been on sale. Just wait for the protagonist to appear. This Yangcheng Lake hairy crab franchise store is 19 years old. Ms. Shang, the owner of the shop, witnessed the changes in the sales model of the Beijing hairy crab. From the beginning, customers only accepted the spot, and would rather wait in line in the store for two or three hours. Later, the crab card sales model appeared. Sales of physical stores. "As a physical store that has been in business for many years, our first order this year has been harvested from the takeaway platform." Ms. Shang said that although this year Yangcheng Lake hairy crabs were absent from the Mid -Autumn Festival reunion banquet, she was paying attention to the breeding situation every day, " Good crabs are not afraid of late, don't worry these days.
