Every year, 20 million of them leave Scottish rivers and travel thousands of miles to Norway and Greenland to feed.
I think the bigger puzzle is how do they find there way to Norway and Greenland?
They can be imprinted on their journey with the route they took but they have never been to the feeding grounds before.

(The welfare state must fail because it is contrary to human nature and diminishes the human spirit.)
On a trip to Scotland last year my party walked across a bridge and observed salmon going/jumping back up a river. Don’t ask me what river.
FYI, PBS is currently running a superb series on volcanoes. A recent episode dealt with how certain Alaskan salmon adapted some 2000 y ears ago, when a volcano erupted and completely blocked their access to the rivers and streams where they spawned. They were somehow, immediately able to modify their behavior. The episode should be on the PBS website.
