Non-Migrant: Yes. At least some populations of this species do not make significant seasonal migrations. Juvenile dispersal is not considered a migration.
Locally Migrant: Yes. At least some populations of this species make local extended movements (generally less than 200 km) at particular times of the year (e.g., to breeding or wintering grounds, to hibernation sites).
Locally Migrant: Yes. At least some populations of this species make annual migrations of over 200 km.
Anadromous. Prior to spawning most adults return to the river, or tributary, in which they hatched (there is some possibly contradictory evidience from Russia). Adults move into fresh water June-September, depending on latitude. Freshwater migrations generally are less extensive than are those of other Pacific salmon (Heard 1991).
