The effects of concentration and particle size of suspended materials on growth and condition of the Pacific oyster (Crassostrea gigas)

Creator:: Wilson, William Joseph
Abstract:: The effects of exposure to suspended silt, kaolin and fuller's earth on growth and condition of Pacific oysters, 16 months of age, were studied. The exposure apparatus maintained a continuous flow of turbid water through chambers containing test oysters. Additional studies measured the filtration rates of oysters exposed to suspended...

Rearing conditions and their effects on growth, food conversion, and survival of English sole (Parophrys vetulus Girard)

Creator:: Williams, Steven Frank
Abstract:: This study consisted of determining some of the conditions for culture of young English sole (Parophrys vetulus Girard) in the laboratory. Rearing of the larvae to the juvenile stage was attempted unsuccessfully; techniques used and problems encountered during culture are discussed. Growth of juveniles was studied at combinations of temperatures...

Effects of bark debris on benthic macro-fauna of Yaquina Bay, Oregon

Creator:: Walker, John David
Abstract:: Benthic samples were collected during the summer, winter and spring seasons from upper Yaquina Estuary, a region used by Georgia- Pacific Corporation for log dumping and storage. Samples came from an active log dump and storage areas as well as areas not associated with log handling activity. The samples were...

Exposure of coho salmon (Oncorhynchus lisutch) to petroleum hydrocarbons : effect on lipid metabolism and aryl hydrocarbon hydroxylase activity

Creator:: Caldarone, Elaine Marie
Abstract:: Coho salmon (Oncorhynchus kisutch) were exposed to sublethal levels of a water-soluble fraction (WSF) of Cook Inlet crude oil for periods ranging from 18 to 31 days, at four acclimation temperatures. The fatty acid composition of phospholipids extracted from muscle, gill, liver, and brain tissues, and, at three of the...

Selected aspects of the pharmacodynamics of malathion in Cancer magister Dana

Creator:: Lebsack, Stephen Grant
Abstract:: The metabolism of malathion in vivo was studied by injection of adult male Dungeness crab, Cancer magister, with 0.75 [mu]g/g wet weight [³H] malathion. At selected times within 24 hours of injection, subsamples of three crabs were taken for analysis of malathion and metabolites. Malathion was extensively activated by oxidative...

Microhabitat utilization by juvenile chinook salmon (Oncorhynchus tshawytscha) in relation to stream discharges in the lower American River of California

Creator:: Jackson, Terry A.
Abstract:: Habitats for juvenile chinook salmon (Oncorhynchus tshawytscha) were observed at a high flow during the spring of 1989 and at a low flow during the spring of 1991 in the lower American River of California. Parameters of microhabitats in eight macrohabitats were measured. Mean column water velocity and total water...

Habitat characteristics associated with abundance of band-tailed pigeons and use of mineral sites in the Pacific Northwest

Creator:: Overton, Cory T.
Abstract:: Index counts for the Pacific Coast race of the band-tailed pigeon (Columba fasciata monilis) have declined by -2% per year since survey efforts began in the 1950's and 60's. Mineral sites, important resources with high ion concentrations, are regularly visited by band-tailed pigeons which nest in surrounding forest lands. I...

Vegetation response to prescribed fire in mountain big sagebrush ecosystems at Lava Beds National Monument, California

Creator:: Ellsworth, Lisa M.
Abstract:: Anthropogenic land use alterations such as livestock grazing and fire suppression have greatly altered sagebrush grasslands of the Great Basin, facilitating invasion of exotic annuals, increases in woody species, and losses of native species. Much of the current research surrounding wildland and prescribed fire in sagebrush dominated ecosystems has focused...

A genetic study of the red-band trout (Salmo sp.)

Creator:: Wilmot, Richard L.
Abstract:: A group of trout that reside in streams of the desiccating lake basins of southeastern Oregon differ markedly from other known Salmo. Known commonly as the red-band trout, this fish was subjected to chromosome analysis for comparison with other species of western North American Salmo. The karyotype of the red-banded...

Ecology of the northern subpopulation of northern anchovy (Engraulis mordax) in the California Current large marine ecosystem

Creator:: Litz, Marisa N. C.
Abstract:: Northern anchovy (Engraulis mordax) are a dominant forage fish in the California Current large marine ecosystem (CCLME). However, little is known about northern anchovy abundance, distribution, age structure, or population fluctuations relative to ocean conditions in the eastern boundary upwelling system off the U.S. West Coast. This thesis includes three...
