I've caught lot's of white kings in the Strait. I've been told by the fisheries guys that most are headed for the Fraser river but the Skagit and one other river have some too. They are a different strain of fish and if you compare the heads you will notice the White king usually has a rounded nose more like a silver. Almost every one I have caught is 30 pounds on the button. Maybe the rounded nose is just a trait of the the Fraser stock I don't no.
