Masu Salmon
The masu salmon (''Oncorhynchus masou''), also known as masu ( ja, マス, , trout) or in Japan, is a species of salmon belonging to the genus '' Oncorhynchus'', found in the North Pacific along Northeast/East Asian coasts from the Russian Far East ( Primorsky, Kamchatka Peninsula, Sakhalin and Kuril Islands) to south through Korea, Japan and Taiwan. A number of subspecies are known, including the widespread nominate subspecies ''yamame'' (''O. m. masou''), the critically endangered Formosan salmon (''O. m. formosanus'') found in certain landlocked freshwater systems of Taiwan, the Biwa trout (''O. m. rhodurus'') endemic of Lake Biwa, and the anadromous or stream-dwelling '' amago'' (''O. m. macrostomus'') restricted to western Japan. On average, this salmon prefers a temperate climate around the latitude of 65-58°N, and in the sea, it prefers a depth of .

James Carson Brevoort
James Carson Brevoort (July 10, 1818 – December 7, 1887) was an American collector of rare books and coins. He served as superintendent of the Astor Library for two years, also serving as trustee. Biography J. Carson Brevoort was born in Bloomingdale, Manhattan on July 10, 1818. He received his early education at home, in France, and at Hofwyl, near Berne, Switzerland. He then studied at the École Centrale des Arts et Manufactures in Paris, and was graduated with the diploma of a civil engineer. On returning to the United States, he accompanied his uncle, James Renwick, one of the commissioners on the northeastern boundary survey. In 1838 he went abroad as private secretary to Washington Irving, U.S. Minister to Spain. After serving a year in this capacity, he spent several years in European travel, and returned home in 1843. Two years later he married the daughter of Judge Leffert Lefferts, of Brooklyn, where he afterward resided, serving on the board of education, and a ...

Nominate Subspecies
In biological classification, 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 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. A taxonomist decides wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iwame Trout
The iwame trout or markless trout is a variety of salmonid fish inhabiting some fresh waters of Japan. It is an intra-specific mutant morph of the masu salmon (''Oncorhynchus masou'') that is characterized by a lack of the lateral spot marks typical of the young fish in most populations. The iwame is a stream-resident morph that does not migrate to the sea. It occurs together with the standard phenotype in some populations. This morph is recessively inherited. This morph occurs in the ''amago'' subspecies ('' Oncorhynchus masou ishikawae'') in Western Japan, and apparently also in the nominate subspecies ''yamame'' (''Oncorhynchus masou masou''), if these are not identical. The morph was scientifically described as a distinct species ''Oncorhynchus iwame'' in 1961 by Kimura Kimura (written: lit. "tree village") is the 17th most common Japanese surname. Notable people with the surname include: *, Japanese novelist *, Japanese footballer *, Japanese botanist *, Japanese idol and ...

Oncorhynchus Masou Macrostomus Being Cooked
''Oncorhynchus'' is a genus of fish in the family Salmonidae; it contains the Pacific salmon and Pacific trout. The name of the genus is derived from the Greek ὄγκος (ónkos, “lump, bend”) + ῥύγχος (rhúnkhos, “snout”), in reference to the hooked snout (the "kype") that the males develop during mating season. Range Salmon and trout with native ranges in waters draining to the Pacific Ocean are members of the genus. Their range extends from Beringia southwards, roughly to Taiwan in the west and Mexico to the east. In North America, some subspecies of '' O. clarkii'' are native in the Rocky Mountains and Great Basin, while others are native to the Rio Grande and western tributaries of the Mississippi River Basin which drain to the Gulf of Mexico, rather than to the Pacific. Several species of ''Oncorhynchus'' have been introduced into non-native waters around the globe, establishing self-sustaining wild populations. The six Pacific salmons of ''Onco ...

Aquaculture
Aquaculture (less commonly spelled aquiculture), also known as aquafarming, is the controlled cultivation ("farming") of aquatic organisms such as fish, crustaceans, mollusks, algae and other organisms of value such as aquatic plants (e.g. lotus). Aquaculture involves cultivating freshwater, brackish water and saltwater populations under controlled or semi-natural conditions, and can be contrasted with commercial fishing, which is the harvesting of wild fish. Mariculture, commonly known as marine farming, refers specifically to aquaculture practiced in seawater habitats and lagoons, opposed to in freshwater aquaculture. Pisciculture is a type of aquaculture that consists of fish farming to obtain fish products as food. Aquaculture can also be defined as the breeding, growing, and harvesting of fish and other aquatic plants, also known as farming in water. It is an environmental source of food and commercial product which help to improve healthier habitats and used to re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crustacean
Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. Some crustaceans ( Remipedia, Cephalocarida, Branchiopoda) are more closely related to insects and the other hexapods than they are to certain other crustaceans. The 67,000 described species range in size from '' Stygotantulus stocki'' at , to the Japanese spider crab with a leg span of up to and a mass of . Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates, by the possession of biramous (two-parted) limbs, and by ...

Latitude
In geography, latitude is a coordinate that specifies the north– south position of a point on the surface of the Earth or another celestial body. Latitude is given as an angle that ranges from –90° at the south pole to 90° at the north pole, with 0° at the Equator. Lines of constant latitude, or ''parallels'', run east–west as circles parallel to the equator. Latitude and ''longitude'' are used together as a coordinate pair to specify a location on the surface of the Earth. On its own, the term "latitude" normally refers to the ''geodetic latitude'' as defined below. Briefly, the geodetic latitude of a point is the angle formed between the vector perpendicular (or ''normal'') to the ellipsoidal surface from the point, and the plane of the equator. Background Two levels of abstraction are employed in the definitions of latitude and longitude. In the first step the physical surface is modeled by the geoid, a surface which approximates the mean sea level over the ocea ...

Temperate Climate
In geography, the temperate climates of Earth occur in the middle latitudes (23.5° to 66.5° N/S of 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 and usually only have precipitation changes. In temperate climates, not only do latitudinal positions influence temperature changes, but 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 persistency of frost. However, other climate classifications set the minimum at . Zones and climates The north temperate zone extends from the Tropic of Cancer (approximately 23.5° north latitude) to the Arct ...

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.

Stream
A stream is a continuous body of surface water flowing within the bed and banks of a channel. Depending on its location or certain characteristics, a stream may be referred to by a variety of local or regional names. Long large streams are usually called rivers, while smaller, less voluminous and more intermittent streams are known as streamlets, brooks or creeks. The flow of a stream is controlled by three inputs – surface runoff (from precipitation or meltwater), daylighted subterranean water, and surfaced groundwater ( spring water). The surface and subterranean water are highly variable between periods of rainfall. Groundwater, on the other hand, has a relatively constant input and is controlled more by long-term patterns of precipitation. The stream encompasses surface, subsurface and groundwater fluxes that respond to geological, geomorphological, hydrological and biotic controls. Streams are important as conduits in the water cycle, instruments in groundw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. Movements are associated with ocean currents and with the availability of food in different areas at different times of year. The migratory movements ...
