What kind of fish is suitable for backwater fish ponds? fish culture techniques and matters needing attention in stagnant fish ponds

Stagnant fish ponds are suitable for mixed culture of mackerel, silver carp, bighead carp, carp, crucian carp and other fish, which can be cultured in the same proportion, and the water bodies of different layers will be well utilized in stagnant fish ponds without artificial feeding. At the same time, it can also improve the utilization rate of input feed.

The environment is very important for any kind of organism, and the water quality of stagnant fish ponds is relatively poor, but for this kind of fish ponds, we can still culture some fish such as silver carp, silver carp, bighead carp, common carp, crucian carp, and so on, according to a certain proportion. If you want to raise more fish in stagnant fish ponds, of course, you need to change the water quality. Let's look down together.

What kind of fish is suitable for backwater fish ponds?

Stagnant fish ponds are suitable for mixed culture of fish, silver carp, bighead carp, common carp, crucian carp and so on. Generally speaking, the proportion of them is 1 to 1. This kind of mixed culture will make good use of different layers of water, and at the same time, it can also improve the utilization rate of input feed. In the case of no artificial oxygen supply, you can consider putting about 1 to 3 fish per square meter, about 40 square meters, and choose fish less than 1 jin. Can put more than 300, can not be too dense, if the weather is dull, appear, there are more floating plants, the surface of the water may also be covered, and if the pond embankment is too high, so it will not be blown by the wind, it is easy to cause hypoxia, in order to increase the density of stocking, but also to prevent fish from getting sick, you can consider buying an aerator.

I. Fish culture techniques in stagnant fish ponds

1. Find live water and divert it into the pond. If there is no source of living water near the stagnant fish pond, such as river water, you have to feed a small amount of fish first. The density should not be too high and it is easy to get sick. If there is living water nearby, find a source of water to divert water into the pond. In this way, the quality of the water will be improved, which is conducive to raising more fish.

2. To clean up the sludge, the stagnant pond should first remove the sewage. If the sludge can be cleaned up smoothly, some harmful microorganisms in the water will be removed, so that some harmful breeding plants can be reduced, and the water can be purified. Fish also have better oxygen, which is conducive to feeding.

3. Drain the sewage sludge and disinfect the pond. For the pool that has been cleaned, it is best to let the sun be exposed to the sun for a week, because the ultraviolet rays of the sun have the effect of sterilization. If exposed to the sun, it is very good for the pond. It can also be sprinkled with quicklime powder, which is about 200 kilograms per mu, or bleach, 1 to 2 kilograms, for disinfection.

4, irrigation fish culture, at this time can be filled with fresh live water, and then according to the area to calculate the number of fish fry, put into the fry for stocking, not too thin, not too dense, we should pay attention to the quality of the water and the health of the fish, and feed it every morning and evening.

Matters needing attention in fish culture in stagnant fish ponds

1. The most important thing in stagnant fish ponds is the lack of oxygen, so it is necessary to find ways to supply oxygen to the ponds. If there is no running water around, an aerator can be used to increase oxygen to the water quality of stagnant fish ponds, which is conducive to the growth of fish. This must be noted.

2. If live water is introduced, it is necessary to lay a filter in the place of the current, which can filter out some bad impurities and improve the quality of the water. In the process of feeding, some water plants must be put in the water, and some live water needs to be added at regular intervals.

The basic conditions of fish culture are water quality, temperature, area and other conditions, and what stagnant fish ponds lack is some of the most important conditions. If you want to turn a stagnant fish pond into a normal fish pond that can be cultured, that is to change its water quality.
