Why do many restaurants have Chinese sturgeon?

This is a domestic ACIPENSER schrenckii, which is an economic fish and is mainly used for food. /view/408788.htm

The individual of ACIPENSER schrenckii is obviously smaller than that of ACIPENSER sinensis, and its head is relatively short and wide.

Acipenser schrenckii is a carnivorous fish. Its digestive system contains not only the pyloric caecum of teleost fish, but also the valve intestine of cartilaginous fish, so it has high hydration and absorption function. The young fish mainly eat benthos, earthworms and aquatic insects; Adult fish feed on aquatic insects, benthos and small fish. In the case of feeding, artificial compound feed can be eaten after domestication.

The appetite of ACIPENSER schrenckii is closely related to the water temperature. When the water temperature is 8~ 12, it begins to eat, but the food intake is small and the growth is slow. With the increase of water temperature, appetite increases gradually, especially 18~25 degrees. After 26 degrees, the food intake gradually decreased.

The highest economic value of ACIPENSER schrenckii is the sturgeon caviar processed from its fish eggs. Sturgeon caviar is a well-known high-grade food at home and abroad, and its export price in China is 200-300 USD per kilogram. The protein content of its meat and fish eggs is extremely high, which are 18. 1% and 26.2% respectively, so it is an advanced nutritional supplement. Sturgeon kiss, fish belly, fish intestines and fish tendons are all excellent dishes, which often appear on the table of state banquets. Its skin can be made into glue, which is made of high-grade leather, so the sturgeon is full of treasures.

In addition, sturgeon has high ornamental value because of its peculiar appearance, and is regarded as a first-class ornamental fish in Southeast Asia, Taiwan Province Province and Hongkong. Therefore, experts predict that in the near future, ACIPENSER schrenckii breeding will become the pillar industry of aquaculture in China, which will promote the reform and development of aquaculture and have great significance for improving the social and economic benefits of aquaculture.
