The Chinese Sturgeon is a member of the Acipenseridae family of Acipenseriformes order, with the scientific name of acipenser sinensis. The local name for this species of fish is Huang yu (黄鱼).

It is an animal strictly protected by the Chinese government, and is thought to have lived at the same time as dinosaurs, dating back to a period 140 million years ago. Because of that, it is sometimes also known as a living fossil. Living fossil is a term for any living species (or clade) of organism which closely resembles species otherwise only known from fossils and has no close living relatives. ...

It can be considered a large fresh water fish, and is 200 to 500 centimeters in body length, with 200 to 500 kilograms in average weight. The largest one can weigh 550 kilograms. A grownup sturgeon measures up to 4 meters long, weighs over 1000 pound, ranking the biggest of all the 27 sturgeons in the world and biggest animal in the Yangtze River. Its head is acuminate, with the mouth under its jaw.

Sturgeon is a comparatively inferior species of fish. It is a transitional species of Cartilaginous fish and bony fish. Species See text Sturgeon (Acipenser) is a genus of fishes, of which some twenty different species are known, from European, Asiatic and North American rivers. ... Cartilage is type of dense connective tissue. ...

The Chinese Sturgeon has a habit of upstream migration, and dwells along the coasts of China's eastern areas and migrate into rivers for propagation upon reaching sexual maturity. Most aquatic animals are food for the young of the Chinese Sturgeon, while the adults feed on aquatic insects, larval, diatom and humic substances. Its reproductive capacity is poor; generally, it takes more than 10 years for Chinese Sturgeon to be sexually mature. Diatoms are a major group of eukaryotic algae, and are one of the most common types of phytoplankton. ...

The Chinese sturgeon is largely dispersed over the main streams of the Yangtze River and coastal regions of Qiantang River, Minjiang River and Pearl River. It is a precious, but endangered species native to China. The Yangtze River (Chinese: 扬子江; pinyin: ) is the longest river in Asia and the third longest in the world after the Amazon in South America and the Nile in Africa. ...

The Chinese Sturgeon is of great academic interest in taxonomy and biology. The channel for adult fish migrating to superior spawning sites such as the Jinsha River in the upstream of Yangtze River was blocked after the construction of the hydropower project, Gezhouba Dam. For this reason, the government has invested huge labor power and financial resources to protect this precious species. At present, some success has been achieved with artificial inducement for spawning and stream discharge for incubation. Built in 1982, the Chinese Sturgeon Museum is part of the Chinese Sturgeon Institution of China which is using such artificial breeding techniques to try to preserve this endangered species. Taxonomy (from Greek ταξινομία (taxinomia) from the words taxis = order and nomos = law) may refer to either the classification of things, or the principles underlying the classification. ...
