Great Lakes Smelts
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 adjace ...

New Zealand Smelt
The New Zealand smelt (''Retropinna retropinna''), also known as the New Zealand common smelt, New Zealand cucumber fish, or silveries is a smelt of the family Retropinnidae, found only in New Zealand New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island count ... at shallow depths in estuaries and rivers. Their length is between 8 and 13 cm. Species description ''Retropinna retropinna'' are elongated silver green fish with clear fins, just larger than palm size. Smelt can be identified by the adipose fin, a small fleshy nub, located halfway between the dorsal fin and the tail. Scales, a forked tail and a distinct “cucumber smell” are other ways of distinguishing Smelt from other species. There are two species of smelt in New Zealand, the common smelt and Stokell's smelt which can only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smelting
Smelting is a process of applying heat to ore, to extract a base metal. It is a form of extractive metallurgy. It is used to extract many metals from their ores, including silver, iron, copper, and other base metals. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind. The reducing agent is commonly a fossil fuel source of carbon, such as coke—or, in earlier times, charcoal. The oxygen in the ore binds to carbon at high temperatures due to the lower potential energy of the bonds in carbon dioxide (). Smelting most prominently takes place in a blast furnace to produce pig iron, which is converted into steel. The carbon source acts as a chemical reactant to remove oxygen from the ore, yielding the purified metal element as a product. The carbon source is oxidized in two stages. First, the carbon (C) combusts with oxygen (O2) in the air to produce carbon monoxide (CO). Second, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smelt-whiting
The Sillaginidae, commonly known as the smelt-whitings, whitings, sillaginids, sand borers and sand-smelts, are a family of benthic coastal marine fish in the order Perciformes. The smelt-whitings inhabit a wide region covering much of the Indo-Pacific, from the west coast of Africa east to Japan and south to Australia. The family comprises only five genera and 35 species, of which a number are dubious, with the last major revision of the family in 1992 unable to confirm the validity of a number of species. They are elongated, slightly compressed fish, often light brown to silver in colour, with a variety of markings and patterns on their upper bodies. The Sillaginidae are not related to a number of fishes commonly called ' whiting' in the Northern Hemisphere, including the fish originally called whiting, ''Merlangius merlangus''. The smelt-whitings are mostly inshore fishes that inhabit sandy, silty, and muddy substrates on both low- and high-energy environments ranging from pro ...

Australian Smelt
The Australian smelt (''Retropinna semoni'') is a small, pelagic silvery freshwater fish found in large numbers in waters of the south eastern Australian mainland. Distribution The fish is endemic to Australia and widely distributed through the coastal drainages of the south eastern part of the mainland. The species is found in coastal drainages from the south east corner of South Australia through Victoria, New South Wales to the Fitzroy River in south east Queensland. It occurs widely in the Murray River and its tributaries and up the Darling as far upstream as Wilcannia. There are isolated populations in the Coopers Creek which drains into Lake Eyre and several smaller ones in north-western New South Wales and southern Queensland. Recent genetic research indicates Australian smelt stocks are composed of 5 highly genetically distinct and as yet undescribed species (Hammer ''et al.'', 2007).

Thaleichthys
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] |
Whitebait Smelt
''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] |
Mediterranean Sand Smelt
The Mediterranean sand smelt, ''Atherina hepsetus'', is a species of fish in the family Atherinidae. Description The body is rather long, slender and moderately flattened. The mouth is protrusible, directed upward with small teeth; the head and body are scaly. The lower jaw has an upper expansion within the mouth (high dentary bone). Two separate dorsal fins, all rays of first and 1-2 anterior rays of second dorsal fin are unsegmented, with the remaining rays segmented. The anal fin is similar to the second dorsal fin, while the caudal fin is forked. Body is silverish white, darker on the back, with the light blue horizontal stripe extending to the tail. The maximum size is up to 20 cm in length. Although rather small, as a carnivorous species, it feeds on pelagic copepods and benthic crustaceans. In the Mediterranean, it spawns from December to May. Habitat It is a pelagic-neritic, brackishwater / marine fish, widespread in the eastern Atlantic coasts of Spain and M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herring Smelt
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.
