There are three main types of bad weather that trigger fish floating ponds. The first is the rainfall weather. During the day, the sunshine is strong, but thunderstorms suddenly occur around the evening, or there is a lack of sunshine during the rainy days. The second is the hot weather. Long time thunder and not rain, the wind is small, the sultry air pressure is low in the last days, and the weather turns cloudy after a long period of fine weather. The third is strong wind weather. During the day, the weather was clear and the temperature was high. South winds were blown and the north wind turned at night. The temperature dropped rapidly. This kind of weather was more common in autumn.
In order to prevent the floating of fish floating ponds, besides doing a good job in pond water quality regulation and management, we must pay attention to watching (listening) weather forecasts, grasping weather changes, and adopting appropriate management measures for different types of bad weather.
1. When bad weather occurs, it is necessary to strengthen night-time patrol inspection so that problems can be found in time and dealt with promptly.
2, when there is bad weather to reduce the amount of feeding, and try to feed in the morning, should not feed night food, so as not to increase the degree of fish floating oxygen deficiency.
3. There are thunderstorm weather and low-pressure sultry weather in the sunny afternoon. It is necessary to start aerators to increase oxygen at noon and reduce the oxygen consumption factor at night.
4, if there is continuous rain in the day and night, sudden rapid cooling of the northwest wind, pool fish has a serious floating head hidden danger, when the pool fish floating in the middle of the night before and after the start of oxygen or flushing with high oxygen content of new water, and boot has been The fish do not float until the next day.
5, there is no aerator equipment, water is not convenient for the pond, we must first prepare a sufficient amount of oxygenation agent, once the pond fish floating head serious, it should be immediately applied to rescue.
Beware of bad weather triggering fish ponds
Aquaculture fishes suffer from floating or flooding accidents due to lack of oxygen in pool water, and are common in summer and autumn. Causes, in addition to poor management and poor water quality in the pond, have a direct relationship with bad weather.
