Research Shows Little Difference Between Fall, Spring Chinook Salmon

Chinook salmon don't all show up at the same time. There are spring runs and fall runs of most salmon, including in the Klamath River.

The separate runs have been considered different subspecies, but recent genetic research shows the fish really are the same, just with a difference in a single part of their genetic makeup.

John Carlos Garza teaches at the University of California-Santa Cruz and works with the federal fish agency, NOAA Fisheries. He is part of the research team that looked at Klamath salmon genetics, and he says the findings strengthen the case for removing four dams from the river.

Garza joins us to add details to the research and its implications.
