It's the season of eating crabs again. However, since June, Suzhou, Jiangsu has experienced more than 40 days of high temperature weather. Many netizens worry about whether the high temperature will affect the normal listing of Yangcheng Lake hairy crabs for the day? On August 28, a local crab farmer told Jimu Journalists that high temperatures affected the entry and molting of hairy crabs, so that hairy crabs were small. Therefore, the crab breeding of individual crabs may increase prices compared to previous years.

High temperature affects the molting of the crab crab

According to the Suzhou Meteorological Observatory, since mid -June this year, the average temperature in Suzhou is extremely high compared with the same period of previous years. The average rainfall is significantly less. The average high temperature day is 45 days, 29 days higher than the year. Among them, the extreme maximum temperature is 40.7 ° C. High temperatures have been affected to varying degrees of high temperatures. In September, many netizens are worried about whether high -temperature weather will affect the listing of Yangcheng Lake hairy crabs?

On August 28, a crab farmer Zhu Qi (pseudonym) in Yangcheng Lake Town, Xiangcheng District, Suzhou City told Jimu Journalists that the previous high -temperature weather did have some impact on the growth of hairy crabs, especially the hairy crabs were greatly affected.

Zhu Qi introduced that for about half a year from the launch of crab seedlings to the listing, hairy crabs have to go through 5 molten shells. Each molten shell, the crab will grow up a little. However, because the temperature of this summer is too high, the hairy crab molting is affected, and some crab molting time is expected to be postponed than in previous years, which may affect the time of marketing of hairy crabs. In addition, the rise of water temperature in the breeding area has also affected hairy crabs to eat.

"After entering high temperature weather, the crabs breeding in my family have almost no longer much more." Zhu Qi said, according to the growth of his hairy crabs, when crabs were listed this year, the specifications may be smaller than in previous years.

In the face of hot weather, Zhu Qi must not only cool down the water through the water, but also pay attention to the solubility problem in the water area of ​​the breeding area. "There is no photosynthetic effect of water plants at night, and high temperature will exacerbate the dissolved oxygen consumption in the water, which can easily cause insufficient dissolved oxygen in the water and cause hairy crabs to be hypoxic." Zhu Qi said that his family has 60 acres of enclosure breeding areas in Yangcheng Lake. It used to use the seven or eight oxygen pumps to add oxygen to the crab pond, and put into oxygen agemptory tablets in the breeding area.

"In the previous years, there were seven or eight oxygen pumps at the same time, but the number of times used was not much. The frequency used this year is relatively high." Zhu Qi said that because his family is very concerned about the solubility problem, his family is because of high temperature There are not many dead crabs, and the number of hairy crabs has not changed much compared to previous years.

Big crab may increase price increase

However, Zhu Qi said that although the hairy crabs of his family are smaller than in previous years, there are also individual crab farmers breeding technology better, and the breeding hairy crabs are relatively large. In the case of everyone’s crabs, this kind of crab may may be possible. The price will increase.

"Now I can only make a prediction based on my own breeding situation. The specific price depends on the needs of the later market." Zhu Qi said that because of high temperature, the cost of maintaining the breeding area this year has increased significantly. The price of crabs is not high, and the income may be worse.

Another crab farmer Luxi (pseudonym) in the town said that his family also had three major paddling areas in Yangcheng Lake, and the high temperatures of hairy crabs breeding in his family were not greatly affected. The hairy crabs in his family have been molting for the last time, and then they can go to the market for a while. "However, there are thousands of acres of crab ponds in the village, all of which are built by crab farmers. The pools are dead water. Unlike the natural waters of Yangcheng Lake, it may be affected by high temperature."

A local aquatic dealer Li Heng (pseudonym) said that although continuous high temperature this year will affect the crab's head, it should not affect the sales of hairy crabs. "There are fewer hairy crabs, but the first batch of crabs were originally early -minded. I want to eat large crabs at least until October." Li Heng said.
