Some effects of dissolved oxygen concentration on feeding, growth and bioenergetics of juvenile Coho salmon

Creator:: Thatcher, T. O.
Abstract:: The effects of three levels of dissolved oxygen (8, 5 and 3 mg/l) upon the feeding, growth and bioenergetics of juvenile coho salmon, Oncorhynchus kisutch (Walbaum), were determined in laboratory studies. Experiments with individual fish were conducted during the summer, fall and spring to measure rates of food consumption, standard...

Nitrogen fixation by scotch broom (Cytisus scoparius L.) and red alder (Alnus rubra Bong.) planted under precommercially thinned Douglas fir (Pseudotsuga menziesii (Mirb.) Franco)

Creator:: Helgerson, O. T.
Abstract:: Red alder (Alnus rubra Bong.), scotch broom (Cytisus scoparius L.) and snowbrush (Ceanothus velutinus Dougi ) were planted under precommercially thinned Douglas-fir (Pseudotsuga iuenziesil Mirb Franco) in the central Oregon Cascades. Plug grown red alder had significantly greater survival than all wildling propagules except for the second broom planting Browsing...

African Catfish Farmers` Perception on Climate Change and Contribution of Catfish Production to Household Income in Lagos State, Nigeria

Creator:: Adeleke, M. L., Amos, T. T., and Fagbenro, O. A.
Abstract:: The perception of catfish farmers on climate change and it effect on the contribution of catfish production to household income in Lagos State, Nigeria were investigated using primary and secondary data as well as structured questionnaire. A multistage random sampling technique was used to select 250 African catfish farmers. Descriptive...

The influence of bait and stereo video on the performance of a video lander as a survey tool for marine demersal reef fishes in Oregon waters

Creator:: Hannah, Robert W. and Blume, Matthew T. O.
Abstract:: We evaluated how the use of bait as a fish attractant influenced the species and size composition 20 of demersal fishes viewed with a stereo video lander, at 160 sampling sites at Stonewall Bank, a 21 deepwater rocky reef complex in Oregon waters. We also studied the effectiveness of stereo...

Tests of an experimental unbaited video lander as a marine fish survey tool for high-relief deepwater rocky reefs

Creator:: Hannah, Robert W. and Blume, Matthew T. O.
Abstract:: We describe the development and practical field testing of a rugged, unbaited video lander as a visual survey tool for fishes inhabiting structurally complex, high-relief, deepwater rocky reefs. Our autonomous, high-resolution, low-light, color video lander system utilized a smooth frame design that incorporated a series of breakaway attachments and inexpensive...

Effect of medium range order on pulsed laser crystallization of amorphous germanium thin films

Creator:: Li, T. T., Aji, L. B. Bayu, Heo, T. W., Santala, M. K., Kucheyev, S. O., and Campbell, G. H.
Abstract:: Sputter deposited amorphous Ge thin films had their nanostructure altered by irradiation with high-energy Ar⁺ ions. The change in the structure resulted in a reduction in medium range order (MRO) characterized using fluctuation electron microscopy. The pulsed laser crystallization kinetics of the as-deposited versus irradiated materials were investigated using the...

Analysis of a Point-Source Integrating-Cavity Absorption Meter

Creator:: Leathers, Robert A., Downes, T. Valerie, and Davis, Curtiss O.
Abstract:: We evaluate the theoretical performance of a point-source integrating-cavity absorption meter (PSICAM) with Monte Carlo simulations and a sensitivity analysis. We quantify the scattering errors, verifying that they are negligible for most ocean optics applications. Although the PSICAM detector response is highly sensitive to the value of the wall reflectivity,...
