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.
Migrates up to thousands of kilometers between freshwater spawning habitat and marine nonspawning habitat. A number of native landlocked populations are known. Resident and anadromous populations may be sympatric in some areas. Returns to natal stream in spring. In New England, adults ascend rivers beginning in spring, with a peak in June and continuing into fall.
