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...

Nehalem River winter steelhead study

Creator:: Weber, Walter, Knispel, Warren, and Oregon. Fish Division
Abstract:: The Nehalem and North Fork Nehalem rivers are the major tributaries of Nehalem Bay, an estuary on Oregon's north coast (Fig 1). The winter steelhead (Salmo gairdneri) and related fisheries of both streams have been the object of a study which began in 1972. Some data from creel surveys 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...

Fatty acids in the eggs and sac fry of steelhead trout (Salmo Gairdneri) : a developmental study

Creator:: Hayes, Lyle Wayne
Abstract:: Developing steelhead trout eggs and sac fry were examined for wet, dry and lipid weights and for fatty acid composition over the period from fertilization until the disappearance of the yolk sac, 69 days after fertilization. The yolk sac and embryo or fry were separated shortly before hatching, and the...
