Salmon (Salmonidae)

Salmon is the common name for several species of fish in the family Salmonidae. Several other fish in the same family are called trout; the difference is often said to be that salmon migrate and trout are resident, but this distinction does not strictly hold true. Salmon live along the coasts of both the North Atlantic and Pacific Oceans. Salmon are intensively produced in aquaculture in many parts of the world.

Typically, salmon are anadromous: they are born in fresh water, migrate to the ocean, then return to fresh water to reproduce. However, there are populations of several species that are restricted to fresh water through their life. Folklore has it that the fish return to the exact spot where they were born to spawn; tracking studies have shown this to be true, and this homing behavior has been shown to depend on olfactory memory.
The salmon spend about one to five years (depending on the species) in the open ocean where they gradually become sexually mature. The adult salmon then return primarily to their natal stream to spawn. In Alaska, the crossing-over to other streams allows salmon to populate new streams, such as those that emerge as a glacier retreats. The precise method salmon use to navigate has not been established, though their keen sense of smell is involved.

Edelweiss, LLC offers wild salmon species belong to the genus Oncorhynchus as well as Char:

Pink salmon (Oncorhynchus gorbuscha), known as humpies in south east and south west Alaska, are found from northern California and Korea, throughout the northern Pacific, and from the Mackenzie River in Canada to the Lena River in Siberia, usually in shorter coastal streams. It is the smallest of the Pacific species, with an average weight of 3.5 lb (1.6 kg) to 4 lb (1.8 kg).

Chum salmon (Oncorhynchus keta) is known as Dog, Keta, or Calico salmon in some parts of the USA. This species has the widest geographic range of the Pacific species: south to the Sacramento River in California in the eastern Pacific and the island of kyushu in the Sea of Japan in the western Pacific; north to the Mackenzie River in Canada in the east and to the Lena River in Siberia in the west.
Male ocean phase Coho salmon
Coho salmon (Oncorhynchus kisutch) is also known in the USA as Silver salmon. This species is found throughout the coastal waters of Alaska and British Columbia and up most clear-running streams and rivers. It is also now known to occur, albeit infrequently, in the Mackenzie River.

Sockeye salmon (Oncorhynchus nerka) is also known in the USA as Red salmon. This lake-rearing species is found south as far as the Klamath River in California in the eastern Pacific and northern Hokkaido island in Japan in the western Pacific and as far north as Bathurst Inlet in the Canadian Arctic in the east and the Anadyr River in Russian Siberia in the west. Although most adult Pacific salmon feed on small fish, shrimp and squid; sockeye feed on plankton that they filter through gill rakers. Kokanee salmon is a land-locked form of sockeye salmon.

Char (Salvelinus) is the name for a number of species of freshwater and saltwater fish belonging to the Salmoninae subfamily of the family Salmonidae.
