Project outline

The discovery of multiple Ceratomyxa shasta genotypes in the Klamath River prompted us to assess other positive drainages for thus-far host specific genotypes.  Here in Oregon, we have many anadromous salmonid stocks in infected waters and my research goals are to type-out which strains of C.shasta are present, and how they affect the various salmon and steelhead stocks. 

Native salmonids in sentinel fish cages will be exposed in known-infected areas of the Willamette and Deschutes river systems. Additionally, water samples and returning adult spawners will be collected. Information on parasite strain distribution and abundance and host preference and impact will help fisheries managers develop new stocking strategies and may further emphasize the need to restrict fish movement between watersheds. 

In the future we plan to expand our studies north to British Columbia's Fraser River and south to the Sacramento River of California. We welcome samples from your waters as well!
