Mark Yuasa's article referenced the idea of a Puget Sound aggregate methodology tied to the idea that blackmouth follow the forage fish, as extracted:

"Another issue surrounding this has been a push by the state Fish and Wildlife sport fishing advisory board to create the winter seasons into an aggregate type similar to what is used on the coast during summer salmon fisheries."

Of concern is that an aggregate approach not allow a "hot" season in one area of Puget Sound to cause another area to be closed leaving fishermen there and the businesses they support to suffer.

Seems that fisheries management is more about managing people than the fish......
