What is the symbol of fish turning over to Tang Qian?

Fish turning over the pond is caused by high temperature or sudden change of temperature in summer, water pollution in the pond, inadequate management and irresistible factors.

Pay attention to pond management before and after turning over the pond: when the weather is abnormal, control the amount of feed to avoid increasing the oxygen consumption of the water body; In case of abnormal weather or rainstorm, check whether the aerator, power supply and circuit are normal to avoid unexpected accidents;

Store disinfection and oxygen-increasing products in advance to prevent accidents, especially oxygen-increasing products, which can be used every 5-8 hours when there is severe hypoxia; When the dead fish turn over the pond, the dead fish and sick fish should be fished out in time for harmless treatment to avoid the breeding of pathogens.

Reasons for raising fish and changing ponds in rural areas

1, the abnormal weather caused the pond to turn over.

Rainstorm weather: the sunshine is strong during the day, but there are sudden thunderstorms around the evening, or the weather lacks sunshine on rainy days;

The weather is sultry: it doesn't rain for a long time, and the wind is small. After several days of sultry weather, the air pressure is low, and after a long sunny day, the weather turns cloudy; 3. Windy weather: The weather is sunny during the day and the temperature is high. At night, the south wind turns to the north wind, and the temperature drops rapidly. This kind of weather is more common in autumn.

2. Management mistakes lead to pond turnover.

Mainly in the adult stage, the sudden power failure was not found, and the aerator was not found to be turned on under the condition of hypoxia. In aquaculture production, similar situations often occur.
