Linkages between life history type and migration pathways in freshwater and marine environments for Chinook salmon, Oncorhynchus tshawytscha

► Migration pathways of ocean and stream-type Chinook salmon are presented here. ► Chinook salmon from costal river systems followed similar migration paths. ► Chinook salmon from the upper larger river systems diverged in migration paths. ► Hypothesized differences in migration patterns differ by regions. ► Implications on conservation of Chinook are dependent on these migrations.
