Abstract

The size, condition, distribution, and migration pathways of juvenile Pacific salmon (pink, chum, sock-eye, coho, and Chinook salmon) were examined along the eastern Bering Sea shelf during August through October 2002. Juvenile salmon were widely distributed along the eastern Bering Sea shelf, but species-specific distributional pattens were found. Juvenile sockeye and chum salmon were large during 2002, suggesting that growth rates were high during their first summer at sea. Seaward migratory pathways for juvenile salmon from Bristol Bay and the Kuskowim and Yukon rivers were inferred from their size distributions along the eastern Bering Sea shelf, and differ from earlier migration models.
