The past several posts raise some interesting questions.
Fish managers know how to increase the numbers of salmon but are they prepared to increase the size of the adult salmon? We have known for quite some time that the average size at maturity is going down, and that this is not good for anyone. Lots of problems arise, as several folks have pointed out (Smalma, Carcassman, Tug).
What needs to be changed to reverse this trend? What actions can be taken to increase the quality (i.e., size) of the returning salmon rather than just the quantity?
Perhaps hatchery practices can be modified to focus on spawning larger adults. The genetic problems associated with doing that need to be balanced against the need to achieve larger adults. And we ought to be re-thinking how we are managing the forage base primarily herring, anchovy, sand lance, and perhaps smelt. Seriously reducing harvest of forage fish that salmon feed on might be a step in the right direction.
I don't pretend to have all the answers but actively managing the North Pacific fishery to increase the size and age at maturity of Chinook salmon might be the next step in helping to conserve these stocks. And in helping the SRKW's.
