Cryo-preservation of viable fish sperm

Creator:: Graybill, James Roger
Abstract:: Fishery researchers have attempted to preserve viable fish sperm for extended periods of time. Only limited success has been achieved with storage of spermatozoa from salmonids. The principal accomplishments of this investigation during the fiscal year 1966-1967 were the development of standard methods for the collection and evaluation of fish...

Changes in size and age at maturity of Columbia River upriver bright fall chinook salmon (Oncorhynchus tshawytscha) : implications for stock fitness, commercial value, and management

Creator:: Beaty, Roy E.
Abstract:: The average size and age of chinook salmon (Oncorhynchus tshawytscha) caught in commercial fisheries along the Pacific Coast of North America have decreased substantially in this century. These declines might be caused in part by changes in size and age at maturity within the stocks contributing to those fisheries. Upriver...

Biology and production of the red-band trout (Salmo sp.) in four southeastern Oregon streams

Creator:: Kunkel, Clair
Abstract:: The red-band trout is native to many small, isolated streams in southeastern Oregon. A study of the red-band population of Three- mile Creek and Reservoir was conducted from August 1973 to June 1975. Data were collected concerning population size, age composition, growth, biomass, recruitment, fecundity, and habitat. During the spring...

A morphometric study of growth and condition in juvenile English sole (Pleuronectes vetulus) relative to environment

Creator:: Weber, Madeleine Demaries
Abstract:: This thesis focuses upon whether stressful aspects of an organism's environment are reflected by that organism's shape. It presents an application of the powerful thin-plate spline and relative warp methods from morphometric analysis to demonstrate the overall utility of morphometrics in detecting environmental stress in an estuarine flatfish, the English...

Epidermal tumors on juvenile English sole (Parophrys vetulus) from Yaquina Bay, Oregon

Creator:: Koike, Bruce Gary
Abstract:: Juvenile English sole (Parophrys vetulus) were collected in Yaquina Bay, Oregon from January, 1986 to March, 1987. Recruitment of young-of-the-year sole occurred from January to June, 1986 and again from December, 1986 to February, 1987. Emigration from Yaquina Bay started in September, 1986, but a small portion of the English...

Niche partitioning by lesser prairie-chickens Tympanuchus pallidicinctus and ring-necked pheasants Phasianus colchicus in southwestern Kansas.

Creator:: Hagen, Chrisitan A., Pitman, James C., Robel, Robert J., Loughin, Thomas M., and Applegate, Roger D.
Abstract:: We conducted this 2-year study to determine if lesser prairie-chickens Tympanuchus pallidicinctus and ring-necked pheasants Phasianus colchicus used the same habitats where their ranges overlapped in southwestern Kansas. Telemetry locations of 50 transmitter-equipped lesser prairie-chickens and 28 pheasants were used to monitor habitat use by the two species. Additionally, vegetation...

Lesser prairie-chicken brood habitat in sand sagebrush: invertebrate biomass and vegetation

Creator:: Hagen, Christian A., Salter, G. Curran, Pitman, James C., Robel, Robert J., and Applegate, Roger D.
Abstract:: Invertebrates are an important food source for grouse chicks, especially within the first 2 weeks of life. Invertebrate abundance is highly patchy and dependent upon herbaceous cover and vegetation structure. We examined the relationship between invertebrate biomass (from sweepnet samples) and habitat structure at lesser prairie-chicken (Tympanuchus pallidicinctus) brood-use and...

Gender identification and growth of juvenile lesser prairie-chickens

Creator:: Pitman, James C., Hagen, Christian A., Robel, Robert J., Loughlin, Thomas M., and Applegate, Roger D.
Abstract:: The ability to ascertain gender and age of juvenile grouse is essential for determining gender-specific population age structure and studying timing of reproductive events, respectively. We examined outer rectrix feathers from juvenile Lesser Prairie-Chickens (Tympanuchus pallidicinctus) captured at 30–40 and 50–60 days post-hatching. Blood samples were collected from most chicks...

Age-specific variation in apparent survival rates of male lesser-prairie-chickens

Creator:: Hagen, Christian A., Pitman, James C., Sandercock, Brett K., Robel, Robert J., and Applegate, Roger D.
Abstract:: We used mark-recapture methods to estimate age-specific apparent survival rates for male Lesser Prairie-Chickens (Tympanuchus pallidicinctus), a gamebird of conservation concern. A total of 311 male prairie-chickens (135 yearlings, 176 adults) were captured and banded during a 5-year study in southwest Kansas. Time-since-marking models were used to estimate apparent survival...
