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...

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...

The adaptive significance of certain enzyme polymorphisms in steelhead trout (Salmo gairdneri)

Creator:: Redding, Joseph Michael
Abstract:: Mean weights, lengths, and condition factors of three isozyme phenotypes of lactate dehydrogenase (LDH) enzyme differed significantly for experimentally reared winter steelhead trout (Salmo gairdneri) fry. Time of emergence from the gravel was unrelated to LDH phenotype. Relative mortality of the phenotypes between eyed-egg stage and emergence was unaffected by...

Steelhead trout otoliths for age, race, and stock analysis

Creator:: McKern, John L.
Abstract:: Growth characteristics of otoliths were used to determine age, and to separate known races and stocks of steelhead trout (Salmo gairdneri). Otoliths were the first calcified structures observed in X-ray photographs of steelhead embryos, and a continuous record of events through life was interpreted from these structures. A direct relationship...

Development and application of steelhead (Oncorhynchus mykiss) kelt identification techniques

Creator:: Evans, Allen F.
Abstract:: The migrations upstream of pre-spawned adult steelhead (Oncorhynchus mykiss) and downstream of post-spawned steelhead (referred to as "kelts") can geographically and temporally overlap in the Snake River, leading to management challenges for populations listed under the Endangered Species Act (ESA). This thesis describes the development and application of a method...
