High temperature season fish ponds pay attention to regulate water quality
In summer, the water temperature is high and the water quality changes rapidly. In addition, the amount of fertilizer used for feeding is relatively large, and fish excretion is strong and can easily pollute the water quality. Therefore, water quality regulation should be strengthened. Usually, fresh water is added once every 7 days to 10 days, and water is added between 15 and 20 minutes each time. When the deterioration of the pool water is severe, water changes should be adopted to maintain good water quality conditions. Intensive culture ponds should be equipped with special oxygen aerators, which can normally be turned on for oxygenation at 14 o'clock to 15 o'clock on sunny days, and can be turned on for oxygenation when there is danger of floating heads.
