	note = {In 1971, after a new fishway was built at Willamette Falls, ODFW introduced summer steelhead into the Upper Willamette River, from stocks from the Siletz and Skamania rivers.  The Skamania fish returned, but the steelhead that originated from Siletz River stock did not, due to infection by a myxosporean parasite, Ceratomyxa shasta. Subeequent testing for resistance to infection showed that the Siletz and Umpqua River stocks are susceptible to this infection. This thesis shows that even disease-resistant stocks can have their resistance weakened by interbreeding with less-resistant strains, a potentially dangerous side-effect of hatcheries.
