Recently, most of our country has experienced a great warming, the maximum temperature around the record high, the south of the Yellow River will reach the peak of warm heat, many places can exceed 30 ° C, Jiangnan, South China local high temperature weather, while many places in the north to record a new high, Hebei, Henan, Shaanxi and other parts of the highest temperature also more than 25 ° C.
Will it stay this hot?
No, the cold wave is on its way!
On the 25th, it will first affect Xinjiang, and then affect northwest China, with the highest temperature in many places in the north returning to the single digits, and the central and eastern parts of the country will also usher in a "big plunge" in temperature from 27 to 28, with local temperatures dropping more than 20 ° C.
Within a week, the whole country staged a "temperature roller coaster", cold and warm big reversal!
Everyone should pay attention to timely adjustment of clothing according to temperature changes, beware of colds.
The sudden change in temperature will not only have an impact on daily life, but also an industry that is deeply affected by the weather and suffers a huge impact.
That is -- aquaculture

As an industry closely linked to the natural environment, traditional fisheries are particularly vulnerable in the face of the relentless blow of extreme weather. Open farming models, such as ponds and cages, are highly dependent on the natural environment, and once they encounter extreme weather, breeding organisms will face a survival crisis.
The high temperature leads to the sharp decline of dissolved oxygen in aquaculture water, causing stress to fish and shrimp, and the cold wave is easy to cause the spread of diseases, bringing huge losses to farmers.
Different from the traditional farming mode, factory recirculating aquaculture, as an innovative farming mode, is becoming a new way to avoid the impact of extreme weather and ensure the sustainable development of fisheries with its unique advantages.
One advantage of this model is that it is not affected by the weather: through temperature control equipment, the water temperature is kept constant, providing the most suitable growth environment for fish; Use oxygenation equipment to ensure sufficient dissolved oxygen in water to avoid anoxia of fish; Through filtration, disinfection and other means to keep the water clean, reduce the occurrence of diseases.
Neither heat nor cold, nor drought nor flood can affect this closed and sophisticated ecosystem, ensuring the healthy growth of farmed organisms.
Of course, the advantages of factory recirculating aquaculture are far more than this: water resources recycling, efficient water saving; Reduce waste water discharge and reduce environmental pollution; Not subject to seasonal restrictions, can be cross-season farming, year-round farming.
With the progress of science and technology and the enhancement of environmental awareness, factory recirculating aquaculture will become the mainstream model of aquaculture in the future. It can not only effectively cope with the challenges brought by extreme weather, but also improve the efficiency of farming, reduce the cost of farming, and provide consumers with safer and high-quality aquatic products.
