Hucho
''Hucho'' is a genus of large piscivorous salmonid fish known as taimens (from Finnish , 'trout', through ), and is closely related to Pacific trout and lenoks (all belonging to the same tribe in the subfamily Salmoninae). Native to the cold rivers and other freshwater habitats in Eurasia, they are threatened by overfishing and habitat loss. The earliest fossil remains of this genus are known from the Late Oligocene to middle Miocene of the Vitim Plateau in Russia. Younger remains are also known from the Late Miocene of Ukraine and the Late Pleistocene of Germany. Fossil specimens of a ''Hucho''-like salmonid have been recovered from the Clarkia fossil beds and other localities from the late Neogene of western North America, suggesting they may have potentially inhabited North America too. Species The currently recognized species in this genus are: In addition, the Sakhalin taimen was formerly placed in this genus, but genetics Genetics is the study of genes, gene ...

Hucho Bleekeri
''Hucho bleekeri'', the Sichuan taimen, is a species of freshwater fish in the salmon family (Salmonidae), endemic to the Yangtze basin in China. Their typical habitat includes mountain streams and small rivers. They are found in rivers and tributaries in the Sichuan, Shaanxi, and Qinghai provinces. The Sichuan taimen is valued in various academic fields, and may prove helpful in studying fish evolution, and the impacts of climate change on inland, cold-water fish species. They are listed as "critically endangered" by the International Union for Conservation of Nature. Species description The Sichuan taimen typically has a dark black, dorsal, and adipose fin; a silvery white underside; and small, irregular dark spots across the body, head, and gill cover. Their coloring can range from a darker orange/red, to a lighter tan/yellow depending on stage of life. They typically have between 125 and 152 scales, 14 gill rakers, and can grow to 72 cm (2 ft 3in) in length. Biolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hucho Hucho
The huchen (''Hucho hucho'') (, from German), also known as Danube salmon or redfish (), is a large species of freshwater fish in the family Salmonidae native to the Danube basin in Central and Eastern Europe. It is the type species of genus '' Hucho'' (a.k.a. the taimens), being closely related (in the same subfamily) to salmon, trout, char and lenoks. Distribution The huchen is endemic to the Danube The Danube ( ; see also #Names and etymology, other names) is the List of rivers of Europe#Longest rivers, second-longest river in Europe, after the Volga in Russia. It flows through Central and Southeastern Europe, from the Black Forest sou ... basin in Europe where the remaining population is threatened primarily by river damming, resulting in habitat fragmentation and loss through river impoundment and disruption of the longitudinal continuity of rivers, cutting away fish from its spawning grounds, with overfishing and fisheries mismanagement as an additional issue in ...

Hucho Ishikawae
''Hucho ishikawae'', the Korean taimen, is a species of salmonid fish found in the border region between North Korea and China, including the Am-nok or Yalu, Dok-ro, Weon-ju and Jang-jin Rivers. Monitoring of the species has been made very difficult because of the lack of access to the areas in which this species occurs and consequently it is rated as data deficient by the IUCN. It is found in flowing water and reaches up to in length. FishBase
FishBase is a global species database of fish species (specifically finfish). It is the largest and most extensively accessed online database on adult finfish on the web.

Salmonidae
Salmonidae (, ) is a family (biology), family of ray-finned fish, the only extant member of the suborder Salmonoidei, consisting of 11 extant genera and over 200 species collectively known as "salmonids" or "salmonoids". The family includes salmon (both Atlantic and Pacific species), trout (both ocean-going and landlocked), Salvelinus, char, Thymallus, graylings, freshwater whitefishes, taimens and lenoks, all coldwater fish, coldwater mid-trophic level, level predatory fish that inhabit the subarctic and cool temperate waters of the Northern Hemisphere. The Atlantic salmon (''Salmo salar''), whose Latin name became that of its genus ''Salmo'', is also the eponym of the family and order names. Salmonids have a relatively primitive appearance among teleost fish, with the pelvic fins being placed far back, and an adipose fin towards the rear of the back. They have slender bodies with rounded fish scale, scales and forked caudal fin, tail fins, and their fish jaw, mouths contain a si ...

Danube Salmon - Huchen (Hucho Hucho)
The Danube ( ; see also #Names and etymology, other names) is the List of rivers of Europe#Longest rivers, second-longest river in Europe, after the Volga in Russia. It flows through Central and Southeastern Europe, from the Black Forest south into the Black Sea. A large and historically important river, it was once a frontier of the Roman Empire. In the 21st century, it connects ten European countries, running through their territories or marking a border. Originating in Germany, the Danube flows southeast for , passing through or bordering Austria, Slovakia, Hungary, Croatia, Serbia, Romania, Bulgaria, Moldova, and Ukraine. Among the many List of cities and towns on the river Danube, cities on the river are four national capitals: Vienna, Bratislava, Budapest, and Belgrade. Its drainage basin amounts to and extends into nine more countries.

Chattian
The Chattian is, in the geologic timescale, the younger of two ages or upper of two stages of the Oligocene Epoch/Series. It spans the time between . The Chattian is preceded by the Rupelian and is followed by the Aquitanian (the lowest stage of the Miocene). Stratigraphic definition The Chattian was introduced by Austrian palaeontologist Theodor Fuchs in 1894. Fuchs named the stage after the Chatti, a Germanic tribe.Berry, Edward W"The Mayence Basin, a Chapter of Geologic History" ''The Scientific Monthly'', Vol. 16, No. 2, February 1923. pp. 114. Retrieved March 18, 2020. The original type locality was near the German city of Kassel. The base of the Chattian is at the extinction of the foram genus ''Chiloguembelina'' (which is also the base of foram biozone P21b). An official GSSP for the Chattian Stage was ratified in October of 2016. The top of the Chattian Stage (which is the base of the Aquitanian Stage, Miocene Series and Neogene System) is at the first appeara ...

10th Edition Of Systema Naturae
The 10th edition of ''Systema Naturae'' (Latin; the English title is ''A General System of Nature'') is a book written by Swedish naturalist Carl Linnaeus and published in two volumes in 1758 and 1759, which marks the starting point of zoological nomenclature. In it, Linnaeus introduced binomial nomenclature for animals, something he had already done for plants in his 1753 publication of ''Species Plantarum''. Starting point Before 1758, most biological catalogues had used polynomial names for the taxa included, including earlier editions of ''Systema Naturae''. The first work to consistently apply binomial nomenclature across the animal kingdom was the 10th edition of ''Systema Naturae''. The International Commission on Zoological Nomenclature therefore chose 1 January 1758 as the "starting point" for zoological nomenclature and asserted that the 10th edition of ''Systema Naturae'' was to be treated as if published on that date. Names published before that date are unavailable, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was the son of a curate and was born in Råshult, in the countryside of Småland, southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Neogene
The Neogene ( ,) is a geologic period and system that spans 20.45 million years from the end of the Paleogene Period million years ago ( Mya) to the beginning of the present Quaternary Period million years ago. It is the second period of the Cenozoic and the eleventh period of the Phanerozoic. The Neogene is sub-divided into two epochs, the earlier Miocene and the later Pliocene. Some geologists assert that the Neogene cannot be clearly delineated from the modern geological period, the Quaternary. The term "Neogene" was coined in 1853 by the Austrian palaeontologist Moritz Hörnes (1815–1868). The earlier term Tertiary Period was used to define the span of time now covered by Paleogene and Neogene and, despite no longer being recognized as a formal stratigraphic term, "Tertiary" still sometimes remains in informal use. During this period, mammals and birds continued to evolve into modern forms, while other groups of life remained relatively unchanged. The first human ...

Clarkia Fossil Beds
The Clarkia fossil beds (also known locally as the Fossil Bowl) is a Miocene Latah Formation lagerstätte near Clarkia, Idaho. The fossil beds were laid down in a lake roughly 15-million-years ago, when a drainage basin was dammed by the flood basalts of the Columbia River Plateau. Narrow and deep, the lake's cold, anoxic water and rapid sedimentation created perfect fossil conditions. The basin itself has remained tectonically stable, with little deformation since then. The fossils indicate that the region's climate was much warmer and wetter than today's, and similar to that of southern Florida.Anonymous( 2006''Digging Up Ancient Treasures in Clarkia.''New West, August Publications.Rember WC (2007''The Clarkia Flora of northern Idaho.''University of Idaho, Moscow, Idaho. Though a number of animal species have been found, the Clarkia fossil beds site is best known for its fossil leaves. Their preservation is exquisite; fresh leaves are unfossilized, and sometimes retain their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
