How to ensure the safety of aquaculture at high temperature?Reporter visit: 24 -hour water cycle to the small crab with the shell "cool down"

Continuous high temperature weather has brought a lot of impact on aquaculture breeding. Some videos circulating on the Internet show that there are a large amount of crab deaths due to high temperatures. So, how can you minimize the loss caused by climate in high temperature weather? At about 3 pm on August 13th, at the high temperature of 38 degrees Celsius, the reporter drove nearly 30 kilometers to come to the Luoma Lake Aquarium Crash Crab Breeding Base in Luoma Lake Aquarium in Hubin New District, Lake Bin New District, Suqian City.

The waterwheel is oxygen, let the water move up to "cool" the crab

"High -temperature weather does have some impact on crab breeding. Dozens of crabs die a pond mouth every day." Zhang Miao, the person in charge of the base, wears a grass hat and is starting the button by the crab pond to increase the water truck to increase the water and let the water move. Get up and "cool down" crabs.

According to Zhang Miao, the current high temperature weather lasted about half a month, and the highest temperature reached 39 degrees Celsius. "High -temperature weather does bring great tests to crab breeding. About ten days ago, the phenomenon of crab death began to appear more than ten days ago. A pond mouth was in dozens of daily."

Rotten water plants and sporadic crabs in the pond

At the side of the crab pond, the reporter saw that there were scattered dead crabs, which were relatively small, and rotten water plants floating on the water, occasionally seeing one or two dead crabs.

According to Zhang Miao, in order to increase the growth of crabs, a water grass named Ilezao needs to be planted in the pond. After the crab is removed from four shells, the crab can quickly increase from 2 two to 4 two or two. Heavy, the double rate increases.

However, in high temperature weather, it is easy to lead to rotten and deterioration of Iraja, produce toxic substances, and have a greater impact on the growth of crabs. Coupled with the current period of crab shell shelling, the shell crab system is weak, which is more sensitive to high temperature weather. The water temperature of 40 degrees Celsius can easily scal the shell crab to death.

Crab died at high temperature

In order to minimize the impact of high temperature weather on crab breeding, Zhang Miao organized workers to salvage rotten waterweed and dead crabs every morning, so as not to pollute the water quality and cause more crabs to die.

"The measures we have taken are that on the basis of the original microporous and oxygen, we add oxygen to the water truck, take a 24 -hour water cycle, let the water move, so that the water temperature is about 35 degrees Celsius." Zhang Miao Zhang Miao. "Zhang Miao. Say.
