The Chinese sturgeon is the oldest vertebrate on Earth and a descendant of the ancient stickleback, the common ancestor of fish, with a history of 140 million years. It lived in the same period as the dinosaurs. Due to a series of primitive characteristics, the Chinese sturgeon is a group between cartilaginous fish (sharks, etc.) and bony fish, and is also a more primitive group among bony fish. It has important academic value in the history of fish evolution. The Chinese sturgeon occupies an extremely important position in classification and is an important reference for studying fish evolution. It has important scientific value and inestimable ecological and social value in studying biological evolution, geology, landforms, sea invasion, sea retreat and other earth changes. However, due to various reasons, this rare animal is on the verge of extinction. Protecting and saving this rare and endangered "living fossil" has far-reaching significance for the development and rational development and utilization of wildlife resources and the maintenance of ecological balance. Some traces of biological evolution can be seen from it, so it is called a living fossil among aquatic organisms.

According to relevant documents in 1834, the model origin of the Chinese sturgeon is China. Although it is not a Chinese specialty, it is famous because its model origin is in China. Later, some people speculated that it was Guangzhou based on the history of China at that time and the work of later generations. This species has been recorded in the Yellow River, Yangtze River, Li River, Ming River and Qingtang River in southwestern Korea and western Kyushu, Japan, but has disappeared from all these areas except the middle and lower reaches of the Yangtze River.

In order to protect this species, the relevant departments have conducted research on breeding, transplanting and releasing for many years. It can now be transplanted to ponds and reservoirs, grows well, and has become a promising freshwater aquaculture fish. The release results are also impressive. By 1992, more than 1 million tails had been released, which gradually increased the resource volume.

Distributed in China, Japan, South Korea, Lao People's Democratic Republic and North Korea. The Chinese sturgeon is the only species in the order Acipenser that crosses the Tropic of Cancer. It is the southernmost species of sturgeon. It has been historically recorded in southwestern Korea and western Kyushu, Japan. In China, the species was historically found in the Yellow River, Yangtze River, Pearl River, Min River and Qingtang River. However, it has become extinct in the Yellow River, Min River, Qiantang River and Pearl River. The species has also become extinct above the Three Gorges Dam in the upper reaches of the Yangtze River and is only distributed in the middle and lower reaches of the Yangtze River and the coast of the Yellow Sea (Yangtze River system).
The Chinese sturgeon lives in large rivers and near the sea and is a bottom fish.
The Chinese sturgeon has an elongated body, with tapering ends, a narrow back, and a flat belly. The head is long and triangular. The snout is long and pointed. The nostrils are large and located in front of the eyes. The water blowhole is slit-shaped. The eyes are small and oval, located in the back half of the head. The distance between the eyes is wide. The mouth is inferior, transversely fissured, protruding, and retractable. The lips are not well developed, with small papillae. There are two pairs of whiskers in the center of the snout, arranged in an arch shape, and their length is shorter than 1/2 of the distance from the whisker base to the front edge of the mouth. The outer whiskers do not reach the corners of the mouth. The gill slits are large and the false gills are well developed. The gill rakers are sparse and short and thick. There is one dorsal fin, which is located posteriorly, with a concave rear edge and starting point in front of the anal fin. The anal fin is opposi
