Migratory behavior of maturing pink salmon in Gastineau Channel, southeast Alaska
Thesis (M.S.) University of Alaska Fairbanks, 1988 Migration and spawning stream selection of maturing pink salmon in the area of Gastineau Channel was studied with respect to: (1) homing of individuals tagged with coded-wire as emergent fry; (2) intermingling and subsequent spawning locus of adults...
