Rainbow trout ( Oncorhynchus mykiss)

Oncorhynchus is a in the Pacific region ( East Asia and western North America ) widespread genus of the family of salmon (Salmonidae ). The name of the genus is derived from the Greek onkos ( hook ) and rynchos (nose ) from. The species of the genus Oncorhynchus are either pure or fresh water fish, migratory fish, which, after their birth in rivers and streams in the sea and spend one or more years. Drag to the spawning migratory species back to their birth waters, but die as opposed to the members of the genus Salmo after spawning.

Oncorhynchus species are very important for the fisheries and exported in canned or smoked. Some species have been naturalized in other parts of the world, the rainbow trout, pink salmon, chum salmon and the silver salmon in the Europe.
