High-density tank fish culture technology, running water high-density fish culture is several times normal.

Choose a place with sufficient water as a fish pond and do a good job of disinfection and sterilization; River water is usually discharged from fish ponds, and water should be changed frequently in fish ponds, and then fresh water should be replenished every 7- 10 days, each time about 20cm deep; The gravel in the fish pond is transported from the river to improve the survival rate of fish; Free-range fish fry should be healthy and consistent in size and specification. If dead fish are found, they should be fished out in time to reduce the chance of getting sick.

First, high-density tank fish culture technology

1, choose a place with sufficient water as a fish pond, and then do a good job of disinfection and sterilization.

2. Drain the water in the fish pond, and the water quality should meet the conditions of fish farming. Generally, river water should be used, and the water in fish ponds should be changed frequently, and then fresh water should be replenished every 7- 10 days, with a depth of about 20cm each time.

3. The sand used in the fish pond is the sand transported from the river, because the fish in the fish pond can survive more easily.

4. The stocked fry should be healthy, the size and specifications should be consistent, the fish pond should be inspected regularly, and the dead fish should be fished out in time to reduce the chance of disease.

5. Feed the fish regularly and adjust the feeding times reasonably according to the eating and weather conditions. You can also set an aerator in the water to increase the oxygen content in the fish pond and prevent the fish from being deprived of oxygen.

Second, high-density fish farming with running water is several times normal.

The yield of high-density fish farming with running water is generally more than 50 times that of normal fish ponds. Characteristics of running water fish culture:

1, the yield of running water fish farming is quite high.

2. Running water fish farming can use modern facilities such as machinery, chemistry and computer to provide and maintain sufficient dissolved oxygen in the water body, so that the water body has good water quality.

3. In areas where water resources and water quantity are scarce and the climate is cold, it is also possible to maintain sufficient oxygen by controlling the temperature, so that the water quality can be purified and recycled.

4. According to the topography of each area, there are many places with running water conditions, and running water fish culture can be carried out with a little modification, which has great potential.

5. Because it is running water, the environment is superior, it can be stocked in high density and the output is high. Moreover, most of the fish are raised with high quality, which makes full use of natural water resources, reduces the cost and generally has good economic, social and ecological benefits.
