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...

A production function analysis of water resource productivity in Pacific Northwest agriculture

Creator:: Holloway, Milton L.
Abstract:: The competition or rivalry for the use of water resources among economic sectors of the Pacific Northwest and among geographical regions of the western United States has intensified in recent years. This rivalry and the long run prospects for water shortages have increased the demand for research concerning the productivity...

Responses of vegetation and sheep to three grazing pressures

Creator:: Thetford, Frank Oren
Abstract:: A study was conducted over a two year period, 1973 through 1974, on perennial ryegrass-subclover pastures with stocking rates of 7.4 (moderate), 9. 9 (heavy), and 12.4 (overstocked) ewes per hectare to establish guidelines on stocking intensity for dryland improved pastures in western Oregon. Climatic conditions varied annually and caused...

Interaction of crop plant population with weed competition in corn (Zea mays L.), bush snap beans (Phaseolus vulgaris L.), and onion (Allium cepa L.) at differing stages of development

Creator:: Williams, Clarence Frank
Abstract:: Yield reductions due to competition of weeds with crop plants can be extremely important. Early weed competition can be as important in reducing crop yield as weed competition for the entire season. The objectives of this study were (1) to determine the weed control achieved by narrow row-cropping patterns, (2)...

The static and dynamic analysis of discretely represented moorings and cables by numerical means

Creator:: Dominguez, Richard Frank
Abstract:: Computer oriented techniques and procedures are presented for the analysis of single and multiple cable systems. Application is made to a two-point mooring system influenced by surface and subsurface hydrodynamic loading. The effects of the various parameters are presented and the numerical method is compared to exact solutions obtained from...

Effects of clearcutting a Douglas-fir stand upon small animal populations in western Oregon

Creator:: Hooven, Edward F. (Edward Frank)
Abstract:: An ecological study of small forest mammals was conducted from 1964 to 1970. The objectives were to obtain chronological information relative to the effects of current logging practices on vegetational succession and small mammal populations. The locale of the study was in the west-central Cascade Mountains of Oregon. The principal...

Influence of marine environment on age and size at maturity, growth, and abundance of chum salmon, Ohcorhynchus keta (Walbaum), from Olsen Creek, Prince William Sound, Alaska

Creator:: Helle, John H.
Abstract:: Effects of the marine environment on age and size at maturity, early marine growth, and abundance of chum salmon, Oncorhynchus keta, were studied at Olsen Creek during 1959-77. Chum salmon returned to Olsen Creek as predominately 3-, 4-, and 5-year fish; however, age composition varied from year to year. The...
