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 a ...

Delta Smelt
The delta smelt (''Hypomesus transpacificus'') is an endangered slender-bodied smelt, about long, in the family Osmeridae. Endemic 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. Delta Smelt are usually found at temperatures of less than 25 °C and prefer temperatures of around 20 °C. They are euryhaline but occur mostly at salinities of 0–7 practical salinity units. 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.

Enoplophthalmus
''Enoplophthalmus'' is an extinct genus of prehistoric freshwater smelt that inhabited Europe during the Oligocene and early Miocene epoches, from the Rupelian to the Aquitanian. It appears to be closely related to the modern capelin (''Mallotus villosus''). Until the description of the Paleocene-aged '' Speirsaenigma'' from Canada, it was the oldest known fossil smelt genus. The following species are known: * †''E. alsaticus'' Gaudant, 1984 - Early Oligocene of France ( Pechelbronn Formation), potentially late Oligocene of Armenia * †''E. rhenanus'' (Weiler, 1963) - Early Miocene ( Aquitanian) of Germany ( Hydrobienkalk Formation) * †''E. robustus'' (Weiler, 1963) - Early Miocene (Aquitanian) of Germany (Hydrobienkalk Formation) * †''E. schlumbergeri'' Sauvage, 1880 (type species) - Early Oligocene of France ( Calcaires de Campagne-Calavon) Indeterminate otoliths of this genus are known from Romania.

Mallotus (fish)
The capelin or caplin (''Mallotus villosus'') is a small forage fish of the Smelt (fish), smelt family found in the North Atlantic, North Pacific and Arctic Ocean, 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, Pinniped, 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.

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 U.S. state, state in the Western United States that lies on the West Coast of the United States, Pacific Coast.

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 sandban ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Smelt
The Smelt or European smelt (''Osmerus eperlanus'') is a species of fish in the family Osmeridae. Appearance The body of the European smelt is typically long, slender and slightly flattened on either side. Larger fish may reach in length. Smelts have a slightly translucent body. The back and sides are grey-green to pink in colour, the flanks bright silver. The tailfin has a dark border. The smelt lives for up to six years. One characteristic is its intense smell, reminiscent of fresh cucumbers. Habitat and life The smelt is a sea fish that lives in the coastal waters of Europe from the Baltic Sea to the Bay of Biscay. A freshwater form, known in Germany as the ''Binnenstint'' ("Inland smelt"), is common in the larger lakes of Northern Europe. The smelt gather and swim about in the underflows of stronger currents in order to spawn above areas of sand. This takes place from the end of February to March, if the water temperature is above . The egg count per female can be as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eulachon
The eulachon ( (''Thaleichthys pacificus''), also spelled oolichan , ooligan , hooligan ), or 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 ''eulachon'' (occasionally seen as oolichan, 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 "Oolichan Trail", the native trade route for oolichan oil. In some parts it is also known as "halimotkw", which can be translated as "savior fish" or "salvation fish", due to its av ...

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. The earliest fossil argentinid remains are indeterminate otoliths from the Barremian Kimigahama Formation of Japan. The presence of these fossils in what is thought to have been a shallow-water environment contrasts with the present occurrence of argentinids in deepwater habitats, suggesting that they must have adapted to deep-sea environments later in the Cretaceous. Otoliths assignable to ''Argentina'' are known from the Late Cretac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
