Cherry Salmon
The masu salmon (''Oncorhynchus masou''), also known as masu () or in Japan, is a species of salmonid belonging to the genus ''Oncorhynchus'', found in the North Pacific along Northeast Asia, Northeast/East Asian coasts from the Russian Far East (Primorsky Krai, Primorsky, Kamchatka Peninsula, Sakhalin and Kuril Islands) to south through Korea, Japan and Taiwan. Although generally accepted as a salmon in the western world, West, the fish is actually regarded as a trout in Japan (its most famous native range) as it is the most commonly seen freshwater salmonid in the Japanese archipelago. A number of subspecies are known, including the widespread nominate subspecies ''yamame'' (''O. m. masou''), the critically endangered Oncorhynchus masou formosanus, Formosan salmon (''O. m. formosanus'') in landlocked waters of Taiwan, the Biwa trout (''O. m. rhodurus'') endemic of Lake Biwa, and the anadromous ''Oncorhynchus masou macrostomus, amago'' (''O. m. macrostomus'') restricted to wester ...

Western World
The Western world, also known as the West, primarily refers to various nations and state (polity), states in Western Europe, Northern America, and Australasia; with some debate as to whether those in Eastern Europe and Latin America also constitute the West. The Western world likewise is called the Occident () in contrast to the Eastern world known as the Orient (). Definitions of the "Western world" vary according to context and perspectives; the West is an evolving concept made up of cultural, political, and economic synergy among diverse groups of people, and not a rigid region with fixed borders and members. Some historians contend that a linear development of the West can be traced from Greco-Roman world, Ancient Greece and Rome, while others argue that such a projection constructs a false genealogy. A geographical concept of the West started to take shape in the 4th century CE when Constantine the Great, Constantine, the first Christian Roman emperor, divided the Roman Em ...

Temperate Climate
In geography, the temperate climates of Earth occur in the middle latitudes (approximately 23.5° to 66.5° N/S of the Equator), which span between the tropics and the polar regions of Earth. These zones generally have wider temperature ranges throughout the year and more distinct seasonal changes compared to tropical climates, where such variations are often small; they usually differ only in the amount of precipitation. In temperate climates, not only do latitudinal positions influence temperature changes, but various sea currents, prevailing wind direction, continentality (how large a landmass is) and altitude also shape temperate climates. The Köppen climate classification defines a climate as "temperate" C, when the mean temperature is above but below in the coldest month to account for the persistence of frost. However, some adaptations of Köppen set the minimum at . Continental climates are classified as D and considered to be varieties of temperate climates, ...

Oncorhynchus Masou Masou-2
''Oncorhynchus'', from Ancient Greek ὄγκος (''ónkos''), meaning "bend", and ῥύγχος (''rhúnkhos''), meaning "snout", is a genus of ray-finned fish in the subfamily Salmoninae of the family Salmonidae, native to coldwater tributaries of the North Pacific basin. The genus contains twelve extant species, namely six species of Pacific salmon and six species of Pacific trout, all of which are migratory (either anadromous or potamodromous) mid-level predatory fish that display natal homing and semelparity. The name of the genus is derived from Ancient Greek ὄγκος (''ónkos''), meaning "bend", and ῥύγχος (''rhúnkhos''), meaning "snout", in reference to the hooked secondary sexual characteristic — known as the kype — that the males develop on the lower jaw tip during mating season. Range Salmon and trout within ''Oncorhynchus'' are native to the tributaries of the North Pacific Ocean, with their native ranges extend from the Bering Sea coasts southwards ...

Oncorhynchus Masou Macrostomus
The amago or the red-spotted masu salmon (''Oncorhynchus masou macrostomus'') is a salmonid fish endemic to western Japan, and a subspecies of the more widespread Northwest Pacific masu salmon or cherry salmon (''Oncorhynchus masou''). It is distinguished by the presence of red or vermilion spots on the body along with black ones, while the nominate form ''O. masou masou'', known as the yamame, only has black ones. The amago is distributed in western Japan, on the Pacific side of the Honshu and Shikoku islands, and on the Inland Sea of Japan side of Kyushu. The subspecies is a subject of aquaculture. It can grow up to length. There are both anadromous (sea-run) and persistently stream-dwelling populations of the amago. Previously it was considered a subspecies of '' Oncorhynchus rhodurus'', a name that currently only refers to the Biwa trout, which has a restricted distribution within the range of the amago.Kato, F.

Anadromous
Fish migration is mass relocation by fish from one area or body of water to another. Many types of fish migrate on a regular basis, on time scales ranging from daily to annually or longer, and over distances ranging from a few metres to thousands of kilometres. Such migrations are usually done for better feeding or to reproduce, but in other cases the reasons are unclear. Fish migrations involve movements of schools of fish on a scale and duration larger than those arising during normal daily activities. Some particular types of migration are ''anadromous'', in which adult fish live in the sea and migrate into fresh water to spawn; and ''catadromous'', in which adult fish live in fresh water and migrate into salt water to spawn. Marine forage fish often make large migrations between their spawning, feeding and nursery grounds. Their movements are associated with ocean currents and with the availability of food in different areas at different times of the year. The migratory ...

Lake Biwa
is the largest freshwater lake in Japan. It is located entirely within Shiga Prefecture (west-central Honshu), northeast of the former capital city of Kyoto. Lake Biwa is an ancient lake, over 4 million years old. It is estimated to be the 13th oldest lake in the world. Because of its proximity to the country's historical capital Kyoto, references to Lake Biwa appear frequently in Japanese literature, particularly in poetry and in historical accounts of battles. Name The name ''Biwako'' was established in the Edo period. There are various theories about the origin of the name ''Biwako'', but it is generally believed to be so named because of the resemblance of its shape to that of a stringed instrument called the ''biwa''. Kōsō, a learned monk of Enryaku-ji in the 14th century, gave a clue to the origin of the name ''Biwako'' in his writing: "The lake is the Pure land of the goddess Benzaiten because she lives on Chikubu Island and the shape of the lake is similar to that of ...

Biwa Trout
The Biwa trout (''Oncorhynchus rhodurus'') is an anadromous salmonid fish of the genus ''Oncorhynchus'', endemic to Lake Biwa in Shiga Prefecture, Japan, but also introduced to Lake Ashi and Lake Chūzenji. While called trout, the fish is most closely related to the masu salmon (''Oncorhynchus masou'') of the western Pacific Ocean, and is most often considered a subspecies of it, ''Oncorhynchus masou rhodurus''.

Oncorhynchus Masou Formosanus
''Oncorhynchus masou formosanus'', commonly known as the Formosan landlocked salmon, cherry salmon, Taiwanese trout (), , Lishan trout (, after its native Lishan area in Heping District, Taichung) or Slamaw trout (from ''Slamaw'', the indigenous Tayal name for Lishan), is an endangered freshwater fish endemic to the mountain stream valleys between the Xueshan and Central Ranges of Taiwan. It is the southernmost subspecies of masu salmon (''Oncorhynchus masou''), and one of the most tropically distributed salmonids along with the Mexican golden trout and Mexican rainbow trout. Description Adult Formosan salmon are about in length, while juveniles are about long on average. Adults can grow up to 57 cm in length at a maximum. It has a dark green body with a silver belly, with nine elliptical dark spots and 11-13 smaller black spots on each side of the body. The male displays a dark red color on the side during mating seasons. In addition to the white and silver colorat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nominate Subspecies
In biological classification, subspecies (: subspecies) is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics ( morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated as subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks.
