Salmothymus
''Salmothymus'' is a genus name of fish in the family Salmonidae, established for the Adriatic trout (''Salmothymus obrusirostris''). More commonly, however, the species is considered a member of the wider genus ''Salmo'', i.e. ''Salmo obtusirostris''.{{FishBase, genus=Salmo, species=obtusirostris, year=2009, month=September ''Salmothymus'' thus is a junior synonym The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name.

Adriatic Trout
''Salmo obtusirostris'', also known as the Adriatic trout, Adriatic salmon, and softmouth trout, is a species of salmonid fish endemic to the rivers of Western Balkans in southeastern Europe. The scientific name has changed several times through history; synonyms include ''Thymallus microlepis'', ''Salmothymus obtusirostris'' and ''Salar obtusirostris''. This species spawns in the early spring and is an obligatory freshwater fish. They are an important game fish. Distribution and subspecies ''Salmo obtusirostris'' is found naturally in four drainages of the Adriatic Sea, in Croatia, Bosnia and Herzegovina and Montenegro: the Neretva- Vrljika system, the Jadro, the Morača-Zeta system, and possibly the Krka river drainage around Knin although it is presumed extinct for some time now. In addition, sometimes during 1960's, it has been introduced from the Jadro river to the nearby Žrnovnica river, both being small karst, single river drainages, of very short course, in vicinity ...

Fish
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Mos ...

Salmonidae
Salmonidae is a family of ray-finned fish that constitutes the only currently extant family in the order Salmoniformes . It includes salmon (both Atlantic and Pacific species), trout (both ocean-going and landlocked), chars, freshwater whitefishes, graylings, taimens and lenoks, which are collectively known as the salmonids ("salmon-like fish"). The Atlantic salmon (''Salmo salar''), whose Latin name became that of its genus ''Salmo'', is also the source of the family and order names. Salmonids have a relatively primitive appearance among the 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 scales and forked tails, and their mouths contain a single row of sharp teeth. Although the smallest species is just long as an adult, most are much larger, with the largest reaching . All salmonids spawn in fresh water of upper reaches of rivers and creeks, but in many cases, the fish spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salmo
''Salmo'' is a genus of ray-finned fish from the family Salmonidae. The single ''Salmo'' species naturally found in the Atlantic North America is the Atlantic salmon, whereas the salmon and trout of the Pacific basin belong to another genus, ''Oncorhynchus''. The natural distribution of ''Salmo'' also extends to North Africa and to West Asia around the Black Sea basin. The generic name ''Salmo'' derives from the Latin ''salmō'' (salmon). The number of distinct species and subspecies in ''Salmo'' is a debated issue. Atlantic salmon and brown trout are widespread species, while most of the other taxa are narrowly distributed forms endemic to single watersheds. Species The species currently listed in this genus are: * ''Salmo abanticus'' Tortonese, 1954 (Lake Abant trout) * ''Salmo aestivalis'' Fortunatov, 1926 (Lake Sevan summer trout) * ''Salmo akairos'' Delling & Doadrio, 2005 (Lake Ifni trout) * ''Salmo aphelios'' Kottelat, 1997 (summer trout) * ''Salmo balcanicus'' ( S. ...

Junior Synonym
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia lev ...

Obsolete Vertebrate Taxa
Obsolescence is the state of being which occurs when an object, service, or practice is no longer maintained or required even though it may still be in good working order. It usually happens when something that is more efficient or less risky replaces it. The international standard IEC 62402:2019 Obsolescence Management defines obsolescence as the "transition from available to unavailable from the manufacturer in accordance with the original specification". Obsolete also refers to something that is already disused or discarded, or antiquated. Typically, obsolescence is preceded by a gradual decline in popularity. Consequences Driven by rapid technological changes, new components are developed and launched on the market with increasing speed. The result is a dramatic change in production methods of all components and their market availability. A growing industry sector is facing issues where life cycles of products no longer fit together with life cycles of required components ...
