A Detailed Guide to Sturgeon Farming Techniques: This Is How Black Gold Is Cultivated

China is rich in sturgeon resources, with many sturgeon species, including the Chinese sturgeon, kaluga sturgeon, Siberian sturgeon and so on, which are now farmed artificially. So, what farming techniques are there for sturgeon? Let's take a look together!

1. Farming preparation

Before farming sturgeon, you need to be fully prepared. Sturgeon has certain requirements in all aspects. The area of the farming site must not be less than five mu, preferably six to nine mu. Next, the pond water must be relatively deep, and the water quality must be clean and pollution-free. The transportation near the farm should be relatively convenient, and a dedicated feed table should be set up inside the farm. Also, you need to prepare an oxygen enhancer or oxygen supply equipment; otherwise, the sturgeon is very likely to die from lack of oxygen. After the farm is built, it needs to be cleaned thoroughly and disinfected with quicklime. After leaving it for three to four days, drain the water. Finally, before stocking, pour chicken manure or the manure of other livestock into the pond to cultivate plankton, so that after the fry are put in they can find food and adapt to the new environment more quickly.

2. Fry selection

The quality of the fry selected determines to a large extent the survival rate of the fry and the later reproduction rate. We should choose healthy sturgeon fry without disease. The sturgeon fry are best around 20 cm, with intact scales and fins, and are relatively lively, looking very nimble when swimming in the water. Sturgeon fry like this are relatively superior.

3. Fry stocking

Before stocking the sturgeon fry, there is one more thing that must be done, as this can reduce fry losses to a certain extent. First, put about ten of the sturgeon fry bought back into the farming pond. After two days, observe whether the fry show any abnormalities. If death occurs or the fry have clearly lost vitality, then it is not suitable to stock fish, and the pond must be cleaned again. If everything is normal, then you can stock with confidence.

4. Feeding management

If you are worried that other problems may occur with the fry put into the pond, you can add a little salt to the water so that the pond water has a certain salinity, but do not add too much, otherwise the sturgeon fry will not be able to adapt and will refuse to eat. Feeding is mainly a combination of the plankton in the water and feed. When feeding, you must pay attention to the fact that the feed can be less but must never be too much, because sturgeon is rather foolish and can be overfed to death. Feed as many times a day as possible, with an appropriate amount each time. Next, sturgeon has relatively high requirements for water quality. Generally, for newly bought fry, we should insist on changing the water once a day. After they have adapted slightly to the environment, changing the water about once a week is enough. For adult sturgeon, changing the water once every half month is fine. Finally, the leftover feed residue on the feeding table in the pond should be cleaned up in time; otherwise, when the fish get hungry they will eat the spoiled feed, causing disease.

5. Pest and disease control

The main pests and diseases of sturgeon are mainly bacterial infections or fungal infections, as well as big belly disease and parasites. Diseases caused by fungal infections are manifested as refusing to eat and being inactive. We should use table salt and baking soda for prevention and control. Bacterial infections are manifested as not growing and bleeding, and can be prevented and controlled with Chinese herbal medicines. Parasites can also be prevented and controlled with Chinese herbal medicines. At the same time, when raising them, we should strengthen feeding management and improve feed quality and nutritional content.
