ASF transitioned in Summer 2012 to a new website, and the SEARCH FUNCTION will occasionally find pages from the old website - pages no longer available. Try other search results for more up-to-date information on the subject. The Search Function will eventually drop the old pages, and be finding only those on the new website.
Note that it is possible also to use the navigation system of the website to find your chosen pages, whether they be related to SALMON NEWS, ISSUES or SCIENCE. An overview of the navigation system is available here.
