Yangcheng Lake hairy crabs were absent from the Mid-Autumn Festival and only came to "eat" at the end of September
24 hours of uninterrupted oxygen inhalation is still "slough", and the production of giant crabs has decreased by nearly 20% this year
The Mid-Autumn Festival is approaching, and when it comes to crab tasting, foodies have already begun to look forward to the launch of Yangcheng Lake hairy crabs. Affected by the continuous high temperature some time ago, the last molting time of Yangcheng Lake hairy crabs has been delayed.
Although the aerator has been used to inhale oxygen 24 hours a day, Yangcheng Lake hairy crabs are still unable to "climb" to the Mid-Autumn Festival table as scheduled.
On September 1, the reporter went to Yangcheng Lake in Suzhou for a field visit. According to the current growth situation, Yangcheng Lake hairy crabs will be officially caught around September 23.
Due to higher costs and reduced production, the price of hairy crabs may increase.
At noon on September 1, the reporter came to Yangcheng Lake in Suzhou and took a speedboat driven by crab farmer Xu Sannan to his breeding base.
Xu Sannan told reporters that the hairy crabs can only go on the market after five moltings. "Due to the rising water temperature this year, the fourth molting of the hairy crabs is a little late, and the fifth molting has not yet started. The continuous high temperature this summer has caused the lake water to go on sale. However, the important part of the growth of hairy crabs, 'molting', needs to be carried out in an environment with sufficient oxygen." Xu Sannan fished a basket of immature hairy crabs from the lake and told reporters: "According to the current shape of hairy crabs Judging by the color and color, it will take the fifth molting to reach the listing standard.”
"This year's output is uncertain. If it is good, it will be about 12,000." Xu Sannan put in 18,000 high-quality crab seedlings this year, and 12,000 last year.
In addition, under normal temperature, the original one tael of hairy crabs can become two taels after shedding their shells once, which is the doubling rate in the mouth of crab farmers.
However, the continued high temperature this year will reduce the doubling rate of hairy crabs. "The weather is hot, the crabs eat less, and the molting will be difficult. At this time last year, there were already a lot of crabs in the crab pond, but this year I saw nothing like in previous years. many."
"Hairy crabs, like people, like to hide in a cool place to molt." The continuous high temperature this year has affected the growth of aquatic plants. In order to make aquatic plants grow more lush, it is necessary to adjust the water quality, which will increase the cost.
In addition, the price of feed for hairy crabs this year has also increased a lot compared with previous years. The price of corn kernels, one of the feeds for hairy crabs, has risen by one-third.
In the face of the continuous high temperature this year, in order to ensure the survival rate of hairy crabs, Xu Sannan used two aerators to ensure sufficient oxygen in the lake water, and also put vitamin C and probiotics into the water.
These measures will undoubtedly increase the cost of raising crabs.
Will the price of hairy crabs rise this year?
Xu Sannan said that the price of the hairy crabs he breeds is the same as last year, which is still the old price. There are five males and five females, more than four taels for males, and more than three taels for females. A box of ten is sold for 700 yuan.
For crab farmers who produce and sell their own products, their prices are often more favorable.
"This year's hairy crabs will be listed after the Mid-Autumn Festival, probably around September 25." Xu Sannan told reporters that Yangcheng Lake hairy crabs will be listed as soon as they are caught. Although it can be confirmed that the fishing will start in late September, it cannot be listed in large numbers.
According to the forecast of the Yangcheng Yuge Hairy Crab Breeding Professional Cooperative, about 50% of the hairy crabs will be 32.5 to 42 this year, and the output of big crabs will decrease by nearly 20% compared with previous years.
Yao Shuisheng, director of the Press Office of the Yangcheng Lake Hairy Crab Industry Association in Suzhou, introduced that it will be difficult for hairy crabs to eat food when the water surface temperature is higher than 30°C. Rising." Yao Shuisheng told reporters.
The reporter visited a number of farmers' markets in Suzhou and Yangcheng Lake hairy crab specialty stores and learned that at present, most of the crabs sold in the farmers market are foreign crabs. In some Yangcheng Lake hairy crab specialty stores, some shopkeepers are selling other products, and some shopkeepers are making hairy crabs. Preparations for listing.
Although the listing of Yangcheng Lake hairy crabs has been delayed this year, all kinds of crab coupons on e-commerce platforms are still selling well.
The reporter consulted a number of Yangcheng Lake hairy crab merchants and learned that crab coupons are currently on sale, and the price of crab coupons this year is basically the same as previous years.
Crab farmer Xu Sannan told reporters that almost all the Yangcheng Lake hairy crabs listed before the catch were fakes, which is also the easiest criterion for consumers to identify authenticity, "because the Yangcheng Lake hairy crabs have not grown up yet, so they cannot meet the quality requirements. , it is impossible to go public in advance.”
