Sturgeon has a high requirement for dissolved oxygen, which is generally required to be above 5 mg/L in water. If the dissolved oxygen in water drops to 4 mg/L, it will lead to slow activity, coma and even suffocation. The oxygen content in domestic water is not so high. It is easy to cause the death of sturgeon. Sturgeon is one of the earliest vertebrates in existence. Acipenser sturgeon belongs to bony fish, radial fin subclass, cartilaginous scleroderma, ACIPENSER. The sturgeon we usually refer to refers to sturgeon-shaped fish. It is one of the most primitive fish groups.
Sturgeon is suitable for living in weak alkaline water with pH of 7. ~ 8. When the pH drops, it means that the carbon dioxide in the water increases, the acidity increases and the dissolved oxygen decreases, which is not good for Chinese sturgeon which requires higher dissolved oxygen. When the pH is too high, it will increase the toxic effect of ammonia nitrogen in water, which is also unfavorable for sturgeon culture.
