What should be paid attention to in fish farming in summer

Summer fish farming is mainly to pay attention to the impact of the weather, the weather will lead to those situations, which should be paid attention to. How to prevent this from happening, and what to do if the following phenomena occur. What to do with it. What are the common adverse conditions for fish growth in summer? please continue to read the following and we will list them in detail.

1. Increase the feed

After the hot weather, the water temperature will also rise, fish in the water activities frequently, so the first physical exertion is very large, the speed of nutrition metabolism is very fast, so it is necessary to replenish nutrition in time. The amount of feed will increase, and it can also increase the number of times and the amount of food, but only as much as the fish can eat in an hour. This avoids the starvation of fish.

2. Maintain water quality

There is a lot of water in the pond, which is generally in the state of continuous input and outflow of living water, so it is still very large to store some water. after the water has been stored for a long time, the nature of the water is easy to change, and alkaline water may become acidic water. This is bad for the growth of some small creatures, and the fish are less able to catch natural food. So they all sprinkle lime once a month, about 0.375 jin of lime per mu of land.

3. Increase oxygen

When the algae in the water grow too much to cover the surface of the water, the fish are easily deprived of oxygen, and the water quality is affected by feeding too much feed, or if the temperature in the water is too high, there will be a lack of oxygen in the water, so it is necessary to use an aerator to increase the oxygen in the water. Clear the pond in time, remove the fertile algae, and finally replace the water in the pond, and the oxygen environment will get better.

4. Control temperature

Summer temperature increases, strong light heat absorption, the most suitable temperature for the growth of fish is about 20 degrees, the temperature will affect the appetite of fish, resulting in the growth of fish slow down. It is often easy to reach more than 30 degrees in summer, so sunshade nets can be used to cover ponds. Or change a small amount of water to neutralize the water temperature.

5. Eliminate algae

Some algal fish are edible, but some are toxic to fish and are so fertile that they can easily cover polluted ponds. The growth ability is better and the growth rate is faster in summer. Therefore, it is necessary to clean up and salvage algae in real time, remove them in time when the algae are first released, and use copper sulfate to eliminate them.

The main purpose of fish culture in summer is to regulate the growth environment of fish, and the key is to control the temperature and increase the feed to maintain good growth. We can't help but let the summer weather affect the growth of fish. The main purpose is to let the fish still grow and develop in summer.
