Effects of inbreeding Coho salmon (oncorhynchus kisutch)

Creator:: Solazzi, M. F. (Mario Frank)
Abstract:: Effects of inbreeding coho salmon (Oncorhynchus kisutch) on survival during early life history, growth, feed efficiency, and resistance to gas bubble disease were studied. No effect of inbreeding could be associated with either F=0.25 or F=0.125. Tetraploidy may help explain the absence of inbreeding depression at these levels.

Biochemical genetic variation among selected populations of chinook salmon (Oncorhynchus tshawytscha) in Oregon and Washington

Creator:: Kristiansson, Anne Christine
Abstract:: Biochemical variation in 12 different chinook populations, sampled from 10 hatcheries along the Columbia River and the Oregon coast, was studied with starch gel electrophoresis. An index was used to describe the genetic differences between pairs of populations. Differences were observed between spring and fall chinook and between Columbia River...

Genetic aspects of lead toxicity in laboratory populations of guppies (Poecilia reticulata)

Creator:: Burger, Carl V.
Abstract:: The heritability of resistance to death from the effects of lead in laboratory guppy populations was determined from comparisons between progeny produced in a nested breeding experiment and from mass selection experiments. Resistance was measured by the time to death. Heritabilities of resistance to lead were estimated to be 0.26...

The heritability of resistance to gas bubble disease of Columbia River fall Chinook salmon, (Oncorhynchus tshawytscha)

Creator:: Cramer, Steven P.
Abstract:: A nested mating experiment in which 20 males were each mated to four different females was used to obtain an estimate of the heritability of resistance to death from gas bubble disease in Columbia River fall chinook salmon (Oncorhynchus tshawytscha). Heritability estimates ranged from 0. 037 to 0. 038. Bioassays...

The feasibility of a consumptive wild trout sport fishery on the North Fork of the Middle Fork of the Willamette River

Creator:: Nicholas, Jay W.
Abstract:: The objective of this study was to determine whether wild populations of trout in the North Fork of the Middle Fork of the Willamette River can support a catch rate of 0.3-0.5 trout per hour at current levels of effort and to predict how different size and bag limits would...

Comparative behavior of the progeny of hatchery and wild steelhead trout (Salmo gairdneri)

Creator:: Bieber, Glen F.
Abstract:: The objectives of this study were to determine whether changes in the selective pressures which occur in a hatchery could cause inherited modifications in the behavior of steelhead trout (Salmo gairdneri) that would affect their survival in the wild. Environmental effects on the behavior of the offspring of hatchery and...

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...

Red Tree Voles: Examining the Potential Factors Limiting Occupancy and Survival in Young Conifer Forests of the Central Oregon Coast Range

Creator:: Durham, William P.
Abstract:: Forested landscapes in the Pacific Northwest have changed drastically in the last Century with large-scale wildfires, and increased extent and frequency of commercial timber harvests. Thus, landscapes once dominated by older forest cover types became a matrix of younger forests with patches of older forests dispersed throughout. These younger forests...

LiDAR as Tool for Assessing Hazard Fuel Reduction Projects

Creator:: Olszewski, Julia H.
Abstract:: Land management practices in much of the western US that included wildland fire suppression have led to greater fuel loads than has been typical of historical fire regimes. In response to the increased wildland fire risk, “restoration” has emerged as a forest management goal. Restoration involves removal of uncharacteristic amounts...
