Salmo Cenerinus
''Salmo cenerinus'' is a species of fish from the family of Salmonidae, in northern Italy from the Po to the Isonzo and on the northern slope of the Apennines. The species was introduced to different waters outside their original distribution area, to which may also include the Isonzo area. In various places it has probably hybridized with introduced trout (''Salmo trutta The brown trout (''Salmo trutta'') is a species of salmonid ray-finned fish and the most widely distributed species of the genus ''Salmo'', endemic to most of Europe, West Asia and parts of North Africa, and has been widely introduced species, in ...''). Description ''Salmo cenerinus'' in lakes grows to 80 centimeters and in rivers to only 40 centimeters body length. Black and dark brown, and red spots are present all over the body. The caudal fin is slightly indented. Lifecycle The species colonized clear, fast-flowing and well-aerated streams in the hill country, and subalpine and alpine lakes, with tw ...

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

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 ...

Po (river)
The Po ( , ) is the longest river in Italy. It flows eastward across northern Italy, starting from the Cottian Alps. The river's length is , or if the Maira (river), Maira, a right bank tributary, is included. The headwaters of the Po are formed by a Spring (hydrology), spring seeping from a stony hillside at Pian del Re, a flat place at the head of the Val Po under the northwest face of Monviso. The Po then extends along the 45th parallel north before ending at a delta projecting into the Adriatic Sea near Venice. Draining a basin of , the Po is characterized by its large Discharge (hydrology), discharge (several List of rivers by length, rivers over 1,000 km have a discharge inferior or equal to the Po). It is, with the Rhône and Nile, one of the three Mediterranean rivers with the largest water discharge. As a result of its characteristics, the river is subject to heavy flooding. Consequently, over half its length is controlled with Levee, embankments. The river flows throu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apennines
The Apennines or Apennine Mountains ( ; or Ἀπέννινον ὄρος; or – a singular with plural meaning; )Latin ''Apenninus'' (Greek or ) has the form of an adjective, which would be segmented ''Apenn-inus'', often used with nouns such as ("mountain") or Greek (), but ''Apenninus'' is just as often used alone as a noun. The ancient Greeks and Romans typically but not always used "mountain" in the singular to mean one or a range; thus, "the Apennine mountain" refers to the entire chain and is translated "the Apennine mountains". The ending can vary also by gender depending on the noun modified. The Italian singular refers to one of the constituent chains rather than to a single mountain, and the Italian plural refers to multiple chains rather than to multiple mountains. are a mountain range consisting of parallel smaller chains extending the length of peninsular Italy. In the northwest they join the Ligurian Alps at Altare. In the southwest they end at Reggio di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hybridisation (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different variety (botany), varieties, subspecies, species or genus, genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera (genetics), chimera. Hybrids are not always intermediates between their parents such as in blending inheritance (a now discredited theory in modern genetics by particulate inheritance), but can show Heterosis, hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductive isolation, reproductively isola ...

Salmo Trutta
The brown trout (''Salmo trutta'') is a species of salmonid ray-finned fish and the most widely distributed species of the genus ''Salmo'', endemic to most of Europe, West Asia and parts of North Africa, and has been widely introduced species, introduced globally as a game fish, even becoming 100 of the World's Worst Invasive Alien Species, one of the world's worst invasive species outside of its native range. Brown trout are highly adaptable and have evolved numerous ecotypes/subspecies. These include three main ecotypes: a riverine ecotype called river trout or Salmo trutta fario, ''Salmo trutta'' morpha ''fario''; a lacustrine ecotype or ''S. trutta'' morpha ''lacustris'', also called the lake trout (not to be confused with the lake trout in North America); and anadromous populations known as the sea trout or ''S. trutta'' morpha ''trutta'', which upon adulthood migrate downstream to the oceans for much of its life and only returns to fresh water to spawn (biology), spawn in th ...

Salmo
''Salmo'' is a genus of ray-finned fish from the subfamily Salmoninae of family (biology), family Salmonidae, and is part of the tribe (biology), tribe Salmonini along with the sister genera ''Salvelinus'' and ''Salvethymus''. Almost all ''Salmo'' species are native only in the Old World (including most of Europe, coastal North Africa and part of West Asia around the Black Sea), the only exception being the Atlantic salmon (''Salmo salar''), which is also naturally found across the North Atlantic in eastern North America. The number of distinct species and subspecies in ''Salmo'' is a debated issue. The Atlantic salmon and brown trout (''Salmo trutta'') are widespread species and have been introduced species, introduced worldwide as pisciculture, farmed food fish or recreational fishing, recreational game fish, while most of the other ''Salmo'' species are narrowly distributed forms endemism, endemic to single drainage basin, watersheds. The name ''Salmo'' derives from the Latin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Maurice Kottelat
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
