On this Wikipedia the language links are at the top of the page across from the article title. This article is about a particular kind of fish. For the food, see Salmon as food. Salmon are important food fish and are intensively farmed in many parts of the world, with Norway being the world’s largest producer of farmed salmon, followed by Chile. Anglo-Norman:saumon, from Old French: saumon, from Latin: salmō. The unpronounced “l” absent from Middle English was later added as a Latinisation to make the word closer to its Latin root.

The term “salmon” comes from the Latin salmo, which in turn might have originated from salire, meaning “to leap”. The seven commercially important species of salmon occur in two genera. Both the Salmo and Oncorhynchus genera also contain a number of species referred to as trout. Within Salmo, additional minor taxa have been called salmon in English, i. Also, there are several other species which are not true salmon, as in the above list but have common names which refer to them as being salmon. Eosalmo driftwoodensis, the oldest known Salmoninae fish in the fossil record, helps scientists figure how the different species of salmon diverged from a common ancestor. United States as king salmon or blackmouth salmon, and as spring salmon in British Columbia.

Pacific Ocean in Japan, Korea, and Russia. Alaska, are found in the western Pacific from Lena River in Siberia to Korea, found throughout northern Pacific, and in the eastern Pacific from the Mackenzie River in Canada to northern California, usually in shorter coastal streams. Eggs in different stages of development: In some, only a few cells grow on top of the yolk, in the lower right, the blood vessels surround the yolk, and in the upper left, the black eyes are visible, even the little lens. Salmon fry hatching—the baby has grown around the remains of the yolk—visible are the arteries spinning around the yolk and small oil drops, also the gut, the spine, the main caudal blood vessel, the bladder, and the arcs of the gills.

Salmon eggs are laid in freshwater streams typically at high latitudes. The eggs hatch into alevin or sac fry. The fry quickly develop into parr with camouflaging vertical stripes. The parr stay for six months to three years in their natal stream before becoming smolts, which are distinguished by their bright, silvery colour with scales that are easily rubbed off. The smolt body chemistry changes, allowing them to live in salt water. The adult salmon then return primarily to their natal streams to spawn. Atlantic salmon spend between one and four years at sea.

When a fish returns after just one year’s sea feeding, it is called a grilse in Canada, Britain, and Ireland. Grilse may be present at spawning, and go unnoticed by large males, releasing their own sperm on the eggs. Prior to spawning, depending on the species, salmon undergo changes. All change from the silvery blue of a fresh-run fish from the sea to a darker colour. Salmon can make amazing journeys, sometimes moving hundreds of miles upstream against strong currents and rapids to reproduce.
