Culture techniques of "Black Gold" Sturgeon

China is rich in Sturgeon resources, and there are many kinds of Sturgeon, including Chinese Sturgeon, Chinese Sturgeon, Siberian Sturgeon and so on. So, what are the culture techniques of Sturgeon? Let's get to know it together.

1. Culture preparation

Full preparation is needed before breeding Sturgeon. Sturgeon has certain requirements for all aspects. The area of the breeding site should not be less than five mu, preferably six to nine mu. The second is that the pool water should be deeper, and the water quality should be clean and pollution-free. The traffic near the farm is more convenient, there should be a special feed table in the farm, and it is necessary to prepare oxygen enhancers or oxygen supply equipment. Otherwise, Sturgeon is very likely to die of lack of oxygen. After the construction of the farm, the farm needs to be cleaned up, disinfected with quicklime, and the water will be discharged after three or four days. Finally, before stocking, the droppings of chicken or other livestock are poured into the pond for plankton culture, so that fish fry can find food and adapt to the new environment more quickly.

2. Fish fry selection

The selection of fish fry largely determines the survival rate of fish fry and the later reproduction rate. Which kind of healthy Sturgeon fry we should choose? the Sturgeon fry had better be about 20 centimeters, and the scales and fins are intact and lively. When swimming in the water, it looks very brisk, such Sturgeon fry is better.

3. Fish fry restocking

There is another thing that must be done before Sturgeon fry is released, which can reduce the loss of Sturgeon fry to a certain extent. first of all, we put about ten Sturgeon fry into the aquaculture pond, and two days later, we observe whether there is anything unusual in the fry. If there is death or the fry has obviously lost its vitality, then it is not suitable to release the fish. We have to clean up the pool again. If everything is normal, we can rest assured.

4. Feeding and management

If the fry put into the pool are afraid of other situations, they can add a little salt to the water so that the water contains a certain salinity, but do not put too much, otherwise the Sturgeon fry will not adapt and go on a hunger strike. Feeding is mainly based on plankton in the water and feed feeding each other, it must be noted that the feed can be less but not more, because Sturgeon is stupid, so it will be held to death. Feed as many times a day as possible, just the right amount each time. The second is that Sturgeon have higher requirements for water quality. Generally speaking, we have to insist on changing water once a day for fry just bought. After it has adapted slightly to the environment, we can change water every other week or so, while adult Sturgeon can change water every half a month. Finally, the remaining feed residue on the breeding table in the fish pond should be cleaned in time. Otherwise, the fish will eat the bad feed and cause disease when they are hungry.

5. Pest control

The main diseases and insect pests of Sturgeon are bacterial infection or fungal infection, belly disease and parasites, etc. The diseases caused by fungal infection are hunger strike, inactivity and so on. We should use salt and baking soda to prevent and cure. Bacterial infection is characterized by no weight gain and bleeding, which can be prevented by Chinese herbal medicine, and parasites can also be controlled by Chinese herbal medicine. At the same time, we should strengthen the feeding management and improve the feed quality and nutritional composition.
