Most physiological studies of fish migration have focused on swimming and energetics; such studies on salmon migration have concentrated primarily on the adult spawning migration, and relatively less is known about juvenile migration.  Data on growth and body-energy reserves of wild spring Chinook salmon (Oncorhynchus tshawytscha) parr and early migrating smolts indicate that energy is accumulated in advance to support migration and that stored protein may serve as an important energy source.
