I am a fisheries biologist in Humboldt County, California. During an adult salmonid migration survey on Sept. 3, I observed a male sockeye salmon in the lower Mad River near the city of Arcata. Adult sockeye were also observed in the Klamath, Smith, and Rogue Rivers by other biologists. As you are aware, these observations were well south of the species' range. I heard that tissue samples were taken from the Rogue River fish for genetic analysis.--Dennis Halligan <dhevonne@humboldt1.com>
