Prediction Methods and Rescue Measures for Fish Pond Overturn
In summer and autumn, when temperatures are high and microbial activity is vigorous, if a fish pond receives large amounts of fertilizer and feed, the fish can easily come to the surface gasping for air due to oxygen deficiency. If rescue measures are not taken in time, the fish will suffocate and die. Therefore, fish pond management should be strengthened at ordinary times, prediction should be done well, and rescue measures should be taken promptly when fish come to the surface gasping for air, so as to prevent fish pond overturn. Signs before overturn: On the afternoon of a hot day, if organic matter in the pond is found fermenting and producing large amounts of bubbles that cover 1/2 of the pond water surface, and a fishy, foul odor can be smelled from far away from the pond, it indicates that pond overturn is about to occur. In weather that alternates between clear and rainy, in windless, muggy thundering weather, or after heavy thunderstorms, observe the fish pond carefully to prevent fish pond overturn. For fish ponds with severe surface gasping, be especially careful to prevent fish pond overturn. In fish ponds where severe surface gasping occurs, pond overturn mostly happens in the middle of the night and early morning.
