Study Probes Why Chinook Salmon Are Trending Younger and Smaller

Computer modelling points to age specific ocean mortality as a reason chinook salmon returning to Alaska rivers are trending younger and smaller. As KUAC’s Dan Bross reports, a recently published study points to the loss of 3-year-old fish, and the possibility the larger chinook may be more targeted by salmon sharks and other marine predators.

Dan has been in public radio news in Alaska since 1993. He’s worked as a reporter, newscaster and talk show host at stations in McGrath, Valdez and Fairbanks. Dan’s experience includes coverage of a wide range of topics, from wolf control to the Trans-Alaska Pipeline and dog mushing.
