I thought this was a great topic! I remember seeing the route arrows extending a little north then arcing west toward Japan and back up to the home river. I did some surfing and here is a site that is both known subject material by many here and some stuff they may find interesting.

A little excerpt....
Steelhead often migrate directly into high-seas waters during their first summer in the ocean. One fish released from a hatchery in Idaho swam to the center of the Gulf of Alaska, a distance of about 890 nautical miles offshore, in only two months. Another from Oregon's Alsea River hatchery was caught south of Kodiak five months later, a distance of at least 1200 miles. These fish must be cruising at speeds of 10 miles per day or more. While most other species of Pacific salmon initially migrate through along the coast of British Columbia and Alaska, juvenile steelhead appear to head directly to the open ocean.
Take this all for what you want!!!!
