Prediction and Rescue of Fish flooding Pond

The temperature is high in summer and autumn, and the microbial activity is active. if the amount of fertilization and feeding in the fish pond is large, it is easy to cause the fish to float due to hypoxia. If it is not rescued in time, the fish will suffocate to death. Therefore, at ordinary times, it is necessary to strengthen the management of fish ponds, do a good job in forecasting, and rescue the phenomenon of floating head of fish in time to prevent fish flooding in the pond.

Signs in front of the floodpond

In the afternoon of hot weather, if it is found that a large number of bubbles are produced by organic fermentation in the pond and cover 1 / 2 of the water area of the pond, the fishy smell can be smelled far away from the pond, indicating that the floodpond is about to happen. When you encounter sunny and rainy weather, windless and muggy thunder weather, or heavy thunderstorm, you should pay attention to observe the fish ponds to prevent the fish from flooding. Fish ponds with serious floating heads should beware of fish flooding ponds. Fish ponds with serious floating heads often occur in the middle of the night and early in the morning.

Rescue measures

Fish ponds with signs of flooding should be filled with fresh water immediately and an aerator should be turned on in the first half of the night until dawn. For fish ponds that are difficult to irrigate and do not have aeration equipment, the following measures can be chosen to rescue them:

First, each mu of water surface with salt 5kg or alum 3kg dissolve in water, spray the whole pool. Second, 100 kg of dry yellow mud per mu of water, 5 kg of salt or 2.5 kg of raw gypsum are mixed into pulp and sprinkled throughout the pool. Third, each mu of water is mixed with 10 kilograms of dry yellow mud and water, then 50 kilograms of human urine is added and sprinkled in the whole pool. Fourth, use the pump to pump water to increase oxygen, but the plank should be tied to prevent the pump from falling into the mud.
