What's with the fish in the pond?

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; Windy weather: It is sunny during the day and the temperature is high. At night, southerly winds and northerly winds blow, 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.

Pond-turning countermeasures:

1. In the case of abnormal weather, adjust the water quality in advance to improve the dissolved oxygen and anti-stress ability of the water body, such as using aquatic products such as Tongwei Jinting, water-improving Jiedu Bao, oxygen-increasing agent, sodium humate, etc., and replenish some new water in advance when conditions permit.

2. Regularly manage the bottom material and water quality of the pond, regularly use Bacillus, photosynthetic bacteria and cultured aquatic products, such as feed companion 1, 2, 4, gold peptide and lactic acid bacteria, and keep the reasonable algae phase and bacteria phase of the water body.

3. Reasonably equipped with aeration equipment, and equipped with 3kw aerator for every 3-5mu pond with 2,000kg/mu; At the same time, the aeration in the feeding area is strengthened. 10-20 mu pond is equipped with 2.2kw micropore aeration, and 60 aeration disks are installed in the feeding area. During the peak period of breeding, the use mode of "12+5" should be strictly followed: it should be turned on at night 12 hours, turned on for 5 hours during feeding during the day, and used all day when there is no oxygen.
