Why do fish ponds easily overflow when the weather changes drastically?

Pond flooding refers to the phenomenon that organisms in the pond, especially fish, float and turn their stomachs. When there is too much feed in the fish pond or polluted water quality (such as pig manure, rotten grass and other rotten substances) flows into it in large quantities In fish ponds, siltation forms at the bottom of the fish pond. When the weather is overheated, fermentation produces a large amount of biogas, resulting in insufficient oxygen in the water in the fish pond, causing the fish to float up to absorb oxygen. Some fish faint due to lack of oxygen and appear to turn their stomachs. Generally, The phenomenon of pond flooding in domestic fish ponds will cause a large number of fish deaths and cause heavy losses. To solve the pond flooding phenomenon caused by this reason, we must pay attention not to cause a large amount of siltation and decaying matter in the fish ponds, and we must frequently salvage Clean, and at the same time start the air pump regularly to maintain a certain amount of oxygen in the pond. It is also possible that toxic substances, such as pesticides, etc. enter the fish pond and cause pond flooding. In this case, the possibility of recovering losses is relatively small. < /p>

Turn on the oxygenator at the right time to avoid the occurrence of oxygen debt. The high temperature season every year is the peak time for fish pond feeding. At this time, the water level in the fish pond is high and the dissolved oxygen in the water is low. In response to this phenomenon, the Sheyang County Science and Technology Household Entry Expert Group proposed some reasonable measures for good pond management. First, you can add new water frequently. On the one hand, adding new water can dilute the turbid water quality caused by excessive feeding and reduce harmful substances such as ammonia nitrogen and nitrite in the water body. On the other hand, adding new water can break the stratification of the water body and avoid the turbidity caused by the sultry weather. Or the harm caused by water convection caused by heavy rain. The second is to use the aerator reasonably. It is very beneficial to run the aerator for two to three hours at noon on a sunny day.

Opening the aerator at noon can form a certain flow of water, allowing oxygen-rich water and oxygen-deficient water to convect, alleviating the lack of oxygen at the bottom of the pond, and at the same time breaking the stratification of the water body. Furthermore, the amount of feeding should be appropriately reduced during high temperature seasons. Feeding too much will increase the burden on the intestinal tract of fish and easily cause enteritis. Excessive feeding may cause the accumulation of residual bait and feces, which will be deposited at the bottom of the pond, causing acidification of the pond bottom, breeding a large number of bacteria, and causing bacterial diseases. Finally, patrol the pond frequently. Patrolling the pond is a direct way to detect fish pond problems in time. When patrolling the pond, you should look at the water, the sky, and the fish. Pay close attention to changes in water quality and color, and frequently test water quality indicators such as pH, ammonia nitrogen, and nitrite. Once the indicators are found to be high, adjust them in time. Pay close attention to the weather conditions, especially in midsummer, when sultry weather often causes pond flooding. When the weather changes suddenly and drastically, turn on the aerator early, spray oxygenators, etc. to prevent the occurrence of pond flooding.
