Sturgeon has a low mouth and is suitable for eating heavy pellet feed. The particle size of feed varies with the individual size of fish. Compared with common freshwater fish, it needs higher protein content. The content of crude protein in the feed for fry should be above 50%, and the content of fish oil should be appropriately increased. The crude protein content in adult fish feed should also be kept above 40%, and vitamins should be added appropriately to maintain a balanced nutrition. Some people in southern China also feed sturgeon with eel feed, but it is reported that long-term feeding will make sturgeon too short and too fat, which is not conducive to further growth.

In terms of disease prevention and control, sturgeon is large, mostly with bone plates and few natural enemies. Moreover, because there is no history of large-scale artificial breeding, the epidemic and fulminant diseases caused by artificial breeding are much less than those caused by general breeding varieties, and there are few reports and treatment methods of fish diseases at home and abroad. It is said in an article that a well-bred fish is a kind of "fish species that don't know fish diseases". Most common diseases are caused by the deterioration of water quality, so "aquaculture, water-based" is extremely accurate in sturgeon culture, which is also the main reason why most people insist on using running water to cultivate sturgeon. ?

However, bacterial diseases will still occur under the condition of low water temperature and poor water quality, so it is necessary to wash the pool frequently and disinfect it regularly with sturgeon disinfectant.

Possible bacterial diseases are:

1) bacterial enteritis, characterized by anal swelling and pain, intestinal mucus can be seen under the microscope, and in severe cases, sturgeon can be added to the feed to make medicinal bait for treatment. ?

2) The lower end of the kiss and around the mouth are red and swollen, which can cause death in severe cases, usually caused by bacteria. You can throw sturgeon health bait and bathe with sturgeon-specific disinfectant. ?

3) During overwintering, due to the low water temperature, fish may turn white and moldy. In order to prevent the disease, feed containing the immune agent of sturgeon anteater can be fed before wintering. If you have any diseases, you can use a special disinfectant bath for sturgeon. ?

In the use of all drugs, we must insist on the toxicity test with a small amount of fish first, so as to avoid unnecessary losses due to the toxic side effects of drugs.
