What are the points for attention in breeding Sturgeon?

Sturgeon is a kind of Sturgeon-shaped fish, the Sturgeon here is not a national protected animal Chinese Sturgeon, but ordinary Sturgeon, Sturgeon adult body size is very large, the general weight can reach 68-250kg, then what are the precautions for Sturgeon culture?

I. Pond conditions

Because Sturgeon is very large after adulthood, the pond area for breeding Sturgeon also needs to be relatively large. Deep water is needed in the pond to ensure adequate water source, and the water quality is clean and clear without pollution. Ponds should be as far away from noisy and noisy places as residential areas, factories and traffic roads as far as possible, but it is also necessary to ensure convenient transportation and communication, and the area of ponds is generally determined by the number of breeding. However, it is usually about 5-10 mu, the water level is generally about 3 meters, to ensure stable water quality, there is a higher value of dissolved oxygen in the water, and independent inlets and oxygen enrichment equipment are set up to prevent the occurrence of anoxia in the pond.

Second, clear the pond and disinfect

15 days before seedling release, pour the water of the pond into 20cm, mix it with quicklime and then sprinkle it all over the pond, thoroughly disinfect the pond and eliminate the toxic substances in the water, then soak the pond for about three days to discharge the water, then soak the bottom of the pond with water, filter it with sieve silk at the inlet and outlet, and then use tea seed cake to clean and disinfect the pond. Before disinfection, break the tea seed cake and soak it in water for 24 hours and sprinkle it all over the pond, so that not only the fish and shrimp in the pond can be killed, but the remaining tea bran can also be used as fertilizer. Ten days before seedling release, the water in the pond is deepened to about 80cm and disinfected with chlorine-containing disinfectant.

3. Stocking of seedlings

When stocking fish fry, we should choose healthy Sturgeon fry without disease, preferably above 20cm. The breeding density is generally 500tails per mu. When stocking, we should consider whether the water temperature is suitable or not, and also consider the listing time of Sturgeon after adulthood. If the fry need to be transported, we should stop feeding the fry about 2 days before transportation, test the water before releasing the fry, and put the Sturgeon fry of the same specification in the cage. Then observe their growth activity, and if there is nothing unusual, they can be released, but the fry need to be put in a bag and then put into the pond to adapt to the temperature of the water.

IV. Daily management

It is necessary to regularly observe the growth of Sturgeon in the pond, at least three times a day, pay special attention to inspection at night and early in the morning, pay attention to the activities of various fish bodies, and prevent hypoxia. In summer, because it is rainy season, the air pressure is relatively low, it is necessary to strengthen pond patrol and find any problems to be dealt with in time, such as using an aerator to increase oxygen in the pond, or to add new water. To prevent the occurrence of flooding ponds, check the growth and health of Sturgeon regularly, and adjust the feeding amount and density appropriately.

The above are the matters needing attention of Tuliu net for breeding Sturgeon, the economic value of Sturgeon is relatively high, and the method of cultivating Sturgeon is also relatively simple, but what we need to pay attention to is the prevention of diseases, and the diseases of Sturgeon are relatively difficult to find. Correct management methods are needed.
