PROJECT TITLE: Survival and out-migration rate in radio-tagged juvenile Iron Gate Hatchery Fall-run Chinook salmon: Linkage to disease data obtained from coded wire tagged cohorts. J. Scott Foott, PhD U.S. Fish & Wildlife Service, CA-NV Fish Health Center 24411 Coleman Hatchery Road, Anderson, CA 96007 email [email protected] ) 530-365-4271 (fax 530-365-7150) BACKGROUND: A high incidence of infection by the myxosporean parasites, Ceratomyxa shasta and Parvicapsula minibicornis , has been documented in Klamath River juvenile Chinook salmon during the spring and summer. These infections lead to lethal disease in a large portion of the infected population. An unanswered question remains on how this disease situation affects overall survival of the juveniles. Iron Gate hatchery is located at the limit of anadromous fish range at River Mile (RM) 191 and releases 4 – 6 million smolts during May and June. A portion (< 6%) of the release group is marked with coded wire tags that allow for the determination of “days at large” upon later recapture in the river. The disease status
