Alaskans pretty well know at this point that king salmon are in trouble. Biologists been looking into why for about a decade now, without a single smoking gun. And that seems to the way it’s going to be—no single answer.
A group of researchers led through the University of Alaska published a study this week probing a little more into the freshwater part of the lives of king salmon, also known as chinook. They focused on fifteen streams in the Cook Inlet basin, from the Chulitna in the north to the Anchor River in the south, to find some answers about how what happens in the freshwater affects king salmon survival. And, like other studies have shown, it’s complicated.
