Several Pacific salmon (Chinook, coho and Steelhead) have been introduced into the US Great Lakes, and have become potamodromous, migrating between their natal waters to feeding grounds entirely within fresh water. Life cycle of anadromous fish. From a U.S. Government pamphlet. (Click image to enlarge.)
Chinook salmon (Oncorhynchus tshawytscha) are also known in the United States as king salmon or "blackmouth salmon", and as "spring salmon" in British Columbia, Canada. Chinook salmon is the largest of all Pacific salmon, frequently exceeding 6 ft (1.8 m) and 14 kg (30 lb). [ 45 ]
An important source of nutrients, such as nitrogen and phosphorus, for rivers in the Pacific Northwest is the spawning of salmon and subsequent death and decomposition of fish up-river. Every fall, ocean salmon at the end of their life cycle swim upriver to spawn before they die.

A salmon run is an annual fish migration event where many salmonid species, which are typically hatched in fresh water and live most of their adult life downstream in the ocean, swim back against the stream to the upper reaches of rivers to spawn on the gravel beds of small creeks.
The sockeye salmon (Oncorhynchus nerka), also called red salmon, kokanee salmon, blueback salmon, or simply sockeye, is an anadromous species of salmon found in the Northern Pacific Ocean and rivers discharging into it. This species is a Pacific salmon that is primarily red in hue during spawning. They can grow up to 84 cm (2 ft 9 in) in length ...

Oncorhynchus is a genus of ray-finned fish in the subfamily Salmoninae of the family Salmonidae, native to coldwater tributaries of the North Pacific basin. The genus contains twelve extant species, namely six species of Pacific salmon and six species of Pacific trout, all of which are migratory (either anadromous or potamodromous) mid-level predatory fish that display natal homing and ...
The life cycle of a salmon begins in a freshwater stream or river that dumps into the ocean. [2] After spending four or five years in the ocean and reaching sexual maturity, many salmon return to the same streams they were born in to spawn. There are several hypotheses on how salmon are able to do this.
