The relative effects of Ceratomyxa shasta on crosses of resistant and susceptible stocks of summer steelhead

Creator:: Wade, Mark
Abstract:: Crosses were made between a stock of summer steelhead (Salmo gairdneri) known to be resistant to infection by Ceratomyxa shasta and stocks of summer steelhead known to be susceptible. Ceratomyxosis, the disease caused by C. shasta was initiated by exposure to Willamette River water. I found that the crosses were...

Yersinia ruckeri : a characterization of the carrier state in steelhead trout (Salmo gairdneri)

Creator:: Hunter, Valerie Antoinette
Abstract:: Fish, asymptomatically infected with Enteric Redmouth Bacterium (ERMB), were tested for their ability to transmit bacteria to non-infected fish. Unstressed carrier fish were unable to transmit enough bacteria to cause epizootics or produce carrier fish. However, when the ERMB carriers were stressed with heat, sufficient bacteria were shed to infect...

Distribution, abundance, and emigration of juvenile steelhead (Oncorhynchus mykiss), and analysis of stream habitat in the Steamboat Creek Basin, Oregon

Creator:: Dambacher, Jeffrey M.
Abstract:: Snorkel dive estimates and an inventory of stream habitat of the juvenile steelhead (Oncorhynchus mykiss) population in the Steamboat Creek basin were made in the summers of 1987 and 1988. Emigration was monitored by fish trapping from spring through fall of 1988. Distribution, abundance, and habitat utilization of juvenile steelhead...

Ecological relation of sympatric steelhead and resident rainbow trout in the Deschutes River, Oregon

Creator:: Zimmerman, Christian E.
Abstract:: Sympatric steelhead and resident rainbow trout (Oncorhynchus mykiss) are known to exist in many rivers throughout the Pacific Rim. Whether sympatric steelhead and resident rainbow trout are polymorphisms within a single gene pool or two reproductively isolated populations has significant implications concerning the study and conservation of this polytypic species....
