It is an ancient fish with scientific research, medicinal and ornamental value, mainly distributed in China, Japan, Korea and Laos.
Brief introduction of species
Acipenser sinensis all appeared in the Upper Cretaceous at the end of Mesozoic, about 65.438+0.4 billion years ago. China once found sturgeon fossils in the Late Jurassic strata of Beipiao, Liaoning Province (65.438+0.4 billion years ago), and named them Beipiao sturgeon. This sturgeon has only one line of lateral line scales on both sides, and the other body surfaces are bare, which is different from that of Chinese sturgeon with five lines of scales.
Sturgeon is one of the most endangered fish. 63% of the species are extremely endangered, the other three may be extinct, and the remaining 30% are threatened or endangered. Therefore, all the living sturgeons are listed in the red list.
