Osmeridae
Smelts are a family of small fish, the Osmeridae, found in the North Atlantic and North Pacific Oceans, as well as rivers, streams and lakes in Europe, North America and Northeast Asia. They are also known as freshwater smelts or typical smelts to distinguish them from the related Argentinidae (herring smelts or argentines), Bathylagidae (deep-sea smelts), and Retropinnidae (Australian and New Zealand smelts). Some smelt species are common in the North American Great Lakes, and in the lakes and seas of the northern part of Europe, where they run in large schools along the saltwater coastline during spring migration to their spawning streams. In some western parts of the United States, smelt populations have greatly declined in recent decades, leading to their protection under the Endangered Species Act. The Delta smelt (''Hypomesus transpacificus'') found in the Sacramento Delta of California, and the eulachon (''Thaleichthys pacificus'') found in the Northeast Pacific and adja ...

Delta Smelt
The delta smelt (''Hypomesus transpacificus'') is an endangered slender-bodied smelt, about long, in the family Osmeridae. Non-Indigenous to the upper Sacramento-San Joaquin Estuary of California, it mainly inhabits the freshwater-saltwater mixing zone of the estuary, except during its spawning season, when it migrates upstream to fresh water following winter "first flush" flow events (around March to May). It functions as an indicator species for the overall health of the Delta's ecosystem. Because of its one-year lifecycle and relatively low fecundity, it is very susceptible to changes in the environmental conditions of its native habitat.Moyle, PB. 2002. Inland fishes of California. University of California Press, Berkeley. Efforts to protect the endangered fish from further decline have focused on limiting or modifying the large-scale pumping activities of state and federal water projects at the southern end of the estuary, thereby limiting water available to farming.

Allosmerus
''Allosmerus'' is a monotypic genus of smelt. Its sole species, ''Allosmerus elongatus'', the whitebait smelt, is an uncommon Northeast Pacific smelt, about which little is known. Originally described as both ''Osmerus attenuatus'' and ''O. elongatus'', these two species were determined to be conspecific in 1946. The fish can grow from in length, has large eyes, a greenish-gray color on its back, and a silver band along its sides. Unlike most other smelt species which generally have no enlarged teeth in the roof of their mouth, the whitebait has single large tooth in the center of its vomer, which is sometimes flanked by a smaller tooth on either side. The adult males of the species have a longer anal fin. Their range extends from Vancouver Island to San Francisco, California, although one fish has been found as far south as San Pedro, California, a specimen which may have been released as live bait. Often abundant in bay areas, whitebait are known to spawn on subtidal sandba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypomesus
''Hypomesus'' is a genus of smelts (Osmeridae), consisting of five species found in the northern hemisphere. Species There are currently five recognized species in this genus: * ''Hypomesus japonicus'' ( Brevoort, 1856) * '' Hypomesus nipponensis'' McAllister, 1963 (Japanese smelt) * ''Hypomesus olidus'' (Pallas, 1814) (Pond smelt) * '' Hypomesus pretiosus'' ( Girard, 1854) (Surf smelt) * '' Hypomesus transpacificus'' McAllister, 1963 (Delta smelt) The pond smelt ''H. olidus'' is widespread across northeastern Asia, Alaska, and northwestern Canada, while the Delta smelt ''H. transpacificus'' is an endangered species of the Sacramento Delta in California California is a state in the Western United States, located along the Pacific Coast.

Eulachon
The eulacheon ( (''Thaleichthys pacificus''), also spelled oolichan , ooligan , hooligan ), also called the candlefish, is a small anadromous species of smelt that spawns in some of the major river systems along the Pacific coast of North America from northern California to Alaska. Etymology The name "candlefish" derives from it being so fatty during spawning, with up to 15% of the total body weight in fat, that if caught, dried, and strung on a wick, it can be burned as a candle. This is the name most often used by early explorers. The name ''eulacheon'' (occasionally seen as ooolichan, ooligan, oulachon, and uthlecan) is from the Chinookan language and the Chinook Jargon based on that language. One of several theories for the origin of the name of the state of Oregon is that it was a corruption from the term "Ooolichan Trail", the native trade route for ooolichan oil. The unrelated sablefish ''Anoplopoma fimbria'' is also called "candlefish" in the United Kingdom. Species de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Retropinnidae
The Retropinnidae are a family of bony fishes that contains the Southern Hemisphere smelts and graylings. They are closely related to the northern smelts (Osmeridae), which they greatly resemble, but not to the northern graylings (''Thymallus''). Species from this family are only found in southeastern Australia and New Zealand. Although a few species are partly marine, most inhabit fresh or brackish water Brackish water, sometimes termed brack water, is water occurring in a natural environment that has more salinity than freshwater, but not as much as seawater. It may result from mixing seawater (salt water) and fresh water together, as in estuari .... References Ray-finned fish families {{Osmeriformes-stub ...

Argentinidae
The herring smelts or argentines are a family, Argentinidae, of marine smelts. They are similar in appearance to smelts (family Osmeridae) but have much smaller mouths. They are found in oceans throughout the world. They are small fishes, growing up to long, except the greater argentine, ''Argentina silus'', which reaches . They form large schools close to the sea floor, and feed on plankton, especially krill, amphipods, small cephalopods, chaetognaths, and ctenophores. Several species are fished commercially and processed into fish meal Fish meal is a commercial product made from whole wild-caught fish, bycatch and fish by-products to feed farm animals, e.g., pigs, poultry, and farmed fish.R.

Mallotus (fish)
The capelin or caplin (''Mallotus villosus'') is a small forage fish of the smelt family found in the North Atlantic, North Pacific and Arctic oceans. In summer, it grazes on dense swarms of plankton at the edge of the ice shelf. Larger capelin also eat a great deal of krill and other crustaceans. Among others, whales, seals, Atlantic cod, Atlantic mackerel, squid and seabirds prey on capelin, in particular during the spawning season while the capelin migrate south. Capelin spawn on sand and gravel bottoms or sandy beaches at the age of two to six years. When spawning on beaches, capelin have an extremely high post-spawning mortality rate which, for males, is close to 100%. Males reach in length, while females are up to long. They are olive-coloured dorsally, shading to silver on sides. Males have a translucent ridge on both sides of their bodies. The ventral aspects of the males iridesce reddish at the time of spawn.

Fish Migration
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 m ...
