20190819 15400600 1.0 TRUE C. shasta (Ceratonova shasta) is a parasite that can adversely affect salmonids and in some instances maybe fatal. This parasite completes its life cycle by infecting polychaete worms (Manayunkia speciosa) in their myxospore stage; then is released as a actinospore which infects salmonids. Steelhead (Oncorhynchus mykiss), Chinook (Oncorhynchus tshawytscha) and Coho (Oncorhynchus kisutch) are species of concern regarding C. shasta infection in the Klamath River. U.S. Fish and Wildlife Service Fish and Aquatic Conservation program's Arcata office in coordination with Oregon State University's John L. Fryer Aquatic Animal Health Laboratory annually collects information on abundance of polychaete worms and infection rates of C. shasta for three reaches on the Klamath River from below the Shasta River confluence to the Scott River confluence. This is the Community Center monitoring transect. osu usfws c-shasta This is a map of the polychaete survey near the community center on the Klamath River Map created by Samantha Adams Fisheries Technician for the Fish and Aquatic Conservation program at the U.S. Fish and Wildlife Service Office Arcata, CA.
