Effective prevention methods for fish surfacing in summer

Livestock Farming 0 views
I. Prediction of fish surfacing 1. In summer, strong sunlight and high temperatures during the day, and weather in the evening. Sudden thunderstorms or a south wind during the day with high water temperature, then a sudden turn to a north wind at night, causing the water temperature to drop rapidly. 2. Continuous overcast and rainy weather, low air pressure, muggy conditions, weak wind, and foggy weather. 3. Long periods of clear weather without rain, fish feeding vigorously, dense water color, and sudden weather changes. II. Rescue of fish surfacing, 1. Add fresh water Adding fresh water increases dissolved oxygen, improves water quality, and expands the range of activity for fish. 2. Turn on the aerator

I. Prediction of fish surfacing

1. In summer, strong sunlight and high temperatures during the day, and weather in the evening. Sudden thunderstorms or a south wind during the day with high water temperature, then a sudden turn to a north wind at night, causing the water temperature to drop rapidly.

2. Continuous overcast and rainy weather, low air pressure, muggy conditions, weak wind, and foggy weather.

3. Long periods of clear weather without rain, fish feeding vigorously, dense water color, and sudden weather changes.

II. Rescue of fish surfacing,

1. Add fresh water Adding fresh water increases dissolved oxygen, improves water quality, and expands the range of activity for fish.

2. Turn on the aerator The aerator stirs the water body, increasing the contact area between the water body and the air and raising the dissolved oxygen content in the water. When the water temperature is 25°C to 30°C, it is still safe to aerate after the fish have been surfacing for 2 hours to 3 hours; but when the water temperature is above 30°C and turtles are surfacing, the aerator must be turned on after 1 hour.

3. Chemical oxygenation If the fish surfacing is relatively severe, while turning on the aerator, some chemical agents should also be used to make the water produce oxygen, mainly ammonium persulfate and calcium peroxide, etc.
