Something to keep in mind, especially with Chinook, is the use of "adult equivalents". This is out of Boldt. Since the fish have to shared, ia calculation is made as to the probability of a fish surviving to adulthood/entering the stream to spawn.

So, simplistically, an adult Chinook gill netted or hook and lined from the river or bay is 1 fish. That same fish, taken as a barely legal blackmouth, may be 0.5 fish, for allocation purposes.

The proposal to take the fish as immatures in "outside" waters actually lets anglers put more dead fish in the boat.

Way back, in the 40's, WDG used to have spring trout openings on rivers. Anglers targeted, with WDG approval, steelhead smolts and presmolts. They did this because they (WDG) believed that there were license-buying anglers who preferred a trout on sunny spring day to a steelhead in the freezing rain. Regardless, for every (say) 5-10 trout taken one less adult steelhead entered the river.

Same with the Chinook. If we choose to take them as immatures, and this will allow for more days on the water and more actual dead fish, then the rivers will see less adults. Hopefully enough to meet escapement goals but that's another discussion.

The angling community, in total, needs to look at the time/area options and see what they choose. But, whatever is chosen will piss off somebody.
