If the oxygen in the water falls below the physiological minimum requirement of the fish, the fish can suffocate. If you do not rescue in time, it will cause a large number of fish deaths. In view of this situation, we must properly control the stocking density, and should appropriately reduce feeding and fertilization when the weather is hot and stuffy. During the winter clearing pond, some silt at the bottom of the pond was dug in order to prevent excessive siltation at the bottom of the pond and affect water quality. High-yield fish ponds should be equipped with aerators and oxygenation should be performed regularly. Feeding should be done in order to determine quality, quantity, timing, and positioning. The remaining feed in the food field should be promptly removed. Fresh water should be immediately poured into the floating head of the diseased fish. The water inlet should be covered with a reed or wood board, and the water should not be poured directly into the bottom of the tank and the sludge should be turned upside down. If necessary, the fish can also be transferred to ponds, and oxygen can also be increased by chemical oxygenation.
