Sinosturio
''Sinosturio'' is a genus of sturgeon native to the Pacific Ocean and associated river drainages in eastern Asia and western North America. Considered synonymous with ''Acipenser'' for nearly a century, it was revived as a distinct genus in 2025 to resolve the polyphyly of the former genus. Most species in this genus were previously placed in ''Acipenser'', aside from the kaluga which was previously placed in ''Huso''. The following species are placed in this genus: * ''Sinosturio'' ''dabryanus'' ( A. H. A. Duméril, 1869) ( Yangtze sturgeon) * '' Sinosturio dauricus'' ( Georgi, 1775) (kaluga Kaluga (, ) is a types of inhabited localities in Russia, city and the administrative center of Kaluga Oblast, Russia. It stands on the Oka River southwest of Moscow. Its population was 337,058 at the 2021 census. Kaluga's most famous residen ...) * '' Sinosturio medirostris'' ( Ayres, 1854) ( green sturgeon) * '' Sinosturio mikadoi'' ( Hilgendorf, 1892) ( Sakhalin sturgeon) * '' Si ...

Sturgeons
Sturgeon (from Old English ultimately from Proto-Indo-European language, Proto-Indo-European *''str̥(Hx)yón''-) is the common name for the 27 species of fish belonging to the family Acipenseridae. The earliest sturgeon fossils date to the Late Cretaceous, and are descended from other, earlier Acipenseriformes, acipenseriform fish, which date back to the Early Jurassic period, some 174 to 201 million years ago. They are one of two living families of the Acipenseriformes alongside paddlefish (Polyodontidae). The family is grouped into five genera: ''Acipenser'', ''Huso'', ''Scaphirhynchus,'' ''Sinosturio'', and ''Pseudoscaphirhynchus''. Two species (''Adriatic sturgeon, H. naccarii'' and ''Dabry's sturgeon, S. dabryanus'') may be extinct in the wild, and one (''Syr Darya sturgeon, P. fedtschenkoi'') may be entirely extinct. Sturgeons are native to subtropical, temperate and sub-Arctic rivers, lakes and coastlines of Eurasia and North America. A Maastrichtian-age fossil found i ...

White Sturgeon
White sturgeon (''Sinosturio transmontanus'') is a species of sturgeon in the family Acipenseridae of the order Acipenseriformes. They are an anadromous (migratory) fish species ranging in the Eastern Pacific; from the Gulf of Alaska to Monterey, California. However, some are landlocked in the Columbia River Drainage, Montana, and Lake Shasta in California, with reported sightings in northern Baja California, Mexico. Taxonomy Prior to 2025, it was placed in the genus ''Acipenser''. However, this placement was long known to be paraphyletic. In 2025, it was moved to the revived genus ''Sinosturio''. Description ''S. transmontanus'' is distinguished by the two rows of four to eight ganoid bony plates between the anus and anal fin, with about 45 rays present in the dorsal fin. Coloring can range from gray to brownish on the dorsal side, paler on the ventral side, and gray fins. Barbels are situated anterior to the mouth, closer to the snout than the mouth. At sexual maturity, '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Yangtze Sturgeon
Dabry's sturgeon (''Sinosturio dabryanus''), also known as the Yangtze sturgeon, Changjiang sturgeon and river sturgeon, is a species of fish in the sturgeon family, Acipenseridae.Zhuang, P., et al. (1997)Biology and life history of Dabry's sturgeon, ''Acipenser dabryanus'', in the Yangtze River.''Environmental Biology of Fishes'' 48(1-4), 257-64. It is endemic to China and today restricted to the Yangtze River basin, but was also recorded from the Yellow River basin in the past. It was a food fish of commercial importance. Its populations declined drastically, and since 1988, it was designated an endangered species on the Chinese Red List in Category I and commercial harvest was banned. It has been officially declared extinct in the wild by the IUCN as of July 21, 2022.

Sakhalin Sturgeon
The Sakhalin sturgeon or Mikado sturgeon (''Sinosturio mikadoi'') is a species of fish in the family Acipenseridae. It is found in Japan and Russia. Taxonomy Prior to 2025, it was placed in the genus ''Acipenser''. However, this placement was long known to be paraphyletic. In 2025, it was moved to the revived genus '' Sinosturio''. Environment The Sakhalin sturgeon is known to be found in either a marine or freshwater environment within demersal depth range. This species is found in brackish waters. They are also native to a tropical climate. Size The Sakhalin sturgeon has reached the maximum recorded length of about 150 centimeters or about 59 inches as a tall fish. Biology The Sakhalin sturgeon is considered to be a species that migrates up the river from the sea in order to spawn. During the months of April to May, the Sakhalin sturgeon feeds in the freshwater and then returns to the ocean during the summer.

Green Sturgeon
The green sturgeon (''Sinosturio medirostris'') is a species of sturgeon native to the northern Pacific Ocean, from China and Russia to Canada and the United States. Taxonomy Prior to 2025, it was placed in the genus ''Acipenser''. However, this placement was long known to be paraphyletic. In 2025, it was moved to the revived genus ''Sinosturio''. Description Sturgeons are among the largest and most ancient of ray finned fishes. They are placed, along with paddlefishes and numerous fossil groups, in the infraclass Chondrostei, which also contains the ancestors of all other bony fishes. The sturgeons themselves are not ancestral to modern bony fishes but are a highly specialized and successful offshoot of ancestral chondrosteans, retaining such ancestral features as a heterocercal tail, fin structure, jaw structure, and spiracle. They have replaced a bony skeleton with one of cartilage, and possess a few large bony plates instead of scales. Sturgeons are highly adapte ...

Sinosturio Sinensis
The Chinese sturgeon (''Sinosturio sinensis''; ) is a critically endangered member of the family Acipenseridae in the order Acipenseriformes. Historically, this anadromous fish was found in China, Japan, and the Korean Peninsula, but it has been extirpated from Korea, Japan, and most regions in China due to habitat loss and overfishing. It is strictly protected by the Chinese government, named a "national treasure" much like its mammalian counterpart, the giant panda. China has several conservation programmes, including reserves specifically aimed at this species and restocking through release of juveniles in the Yangtze River. Taxonomy Prior to 2025, it was placed in the genus ''Acipenser''. However, this placement was long known to be paraphyletic. In 2025, it was moved to the revived genus ''Sinosturio''. Physical appearance Sturgeon are comparatively basal species of fish, whose earliest fossils date back to the Cretaceous period. They are best-known members of the bon ...
