Abstract Excerpt:
Japanese stocks of chum salmon (Oncorhynchus keta) are released in spring, spend several months near the coast of Japan, then migrate to the Okhotsk Sea, where they remain until late fall (Urawa 2000; Azumaya and Ishida 2004) (Fig. 1). The fish then migrate toward the western North Pacific, where they overwinter, then migrate into the Bering Sea by the following summer. In the fall, they move into the Gulf of Alaska in the eastern North Pacific, where they spend one winter. They repeat the migration track between the Bering Sea (summer) and the Gulf of Alaska (winter) 3–4 times, and then return to Japan when approaching maturity in the summer of their fourth to fifth year.
