1, Different species: There are many species of sturgeon. Up to now, there are 27 species of sturgeon. Among them, the common species are Siberian sturgeon, Darwinian sturgeon, small sturgeon, Chinese sturgeon and white sturgeon, so it can be seen that sturgeon includes Chinese sturgeon.

2. Different distribution ranges: Most sturgeons live in the eastern part of Europe, and the sturgeons distributed here account for the majority of the sturgeons in the world. Acipenser sinensis is mainly distributed in the Yangtze River basin in China, although it is also distributed in other countries, but the number is very small.

3, the degree of rarity is different: sturgeon is already a relatively high-grade ingredient, and it is also more precious. However, the number of Chinese sturgeon is even smaller, and it has been listed as a protected animal in China.

Characteristics of ACIPENSER sinensis

Acipenser sinensis is a species of sturgeon, but compared with other species, their number is less, and many people call them "giant pandas in the water". Chinese sturgeons have migratory habits. In summer and autumn, they will swim from the shallow sea outside the Yangtze River estuary to the Yangtze River. Moreover, they will enter the Jinsha River to lay eggs, and when the young fish grow to 15 cm, they will swim near the sea with the young fish. Therefore, Chinese sturgeon is a kind of fish born in rivers and growing in the sea.

ACIPENSER sinensis is characterized by a spindle-shaped body, a long snout at the tip of the head, four snouts in front of the mouth, and the mouth is located on the ventral surface, which is flexible and can stretch into a tube shape. The body is covered with five lines of large and hard bone scales, one line on the back, two lines on the body side and two lines on the ventral side. The caudal fin is crooked, the lateral fin has a broad base, and the dorsal fin is opposite to the gluteal fin.
