Hi BrianM. I sent an email to emi (link to her email was in the link you published above).
Poking around led me to this:
http://www.westcoast.fisheries.noaa.gov/fisheries/salmon_steelhead/PSsalmon_eis_noi.htmlIn your link, 3 high level options are listed, and a favorite is designated; I believe it adds exploitation rate to some stocks that are not currently using exploitation rate.
As the link I provided indicates, the previous plan expired in 2014 & this new one is a plan for the next 10 years.
Further reading by me finds that under the present plans, none of the ESA listed stocks are recovering, and that interception of these stocks in SEAK & BC is a major & well-known problem; with well over 50% of total mortality of many stocks happening up north.
A guide I know in BC is very active in fisheries negotiations & he indicates the party's who negotiate the Pacific Salmon Treaty are well-aware of this & similar problems which is fishing of mixed stocks of healthy and at-risk Chinook without regard to impacts on the at-risk stocks. The Chinook portion of the treaty will be renewed in 2018.
FYI under the last Chinook treaty in 2009 or so we gave Canada $30million to buy-back commercial troll licenses for the WCVI fleet; the largest interceptor of Puget Sound Chinook. I am on a forum in BC & according to commercial trollers on the forum, 9 years later only half the money has been spent & canada DFO has been offering low-ball offers to the fishers.
