Creator:: Hopkins, Karl T.
Abstract:: Many streams in eastern Oregon are listed as water quality impaired on the basis of water temperature. However, it is often difficult to predict water temperature for these streams even if there are no anthropogenic impacts. We measured air and water temperature and stream characteristics on three Type C and...

Creator:: Srinivasan, Haribaskar
Abstract:: Callipyge (CLPG, n=16) and normal (N, n=11) lambs were produced from Polypay dams and Dorset sires heterozygous for the CLPG gene to study the effects of the gene on growth and carcass and meat quality parameters. CLPG lambs had higher average daily gain than N lambs (0.26 vs 0.23 kg/day,...

Creator:: Lin, Dongdong
Abstract:: The characteristics of Northern squawfish (Ptychocheilus oregonensis) and the feasibility of utilization of this species for human consumption were investigated. In the first experimental phase, the iced storage characteristics of squawfish were determined. Quality changes were monitored over 24 days of storage by chemical, physical, microbiological and sensorial methods of...

Creator:: Abdennadher, Mourad
Abstract:: The success of a plant breeding program depends upon the availability of useable genetic diversity. Such diversity may be enhanced depending on the type of hybridization strategy employed. Segregating progenies resulting from F2 populations, a double cross, and a top cross were compared for the amount of useable genetic diversity...

Creator:: Hirai, Takayuki
Abstract:: To understand the influence of selective harvesting on the adaptive capacity of fish populations in changing environments, a computer simulation model was developed. In the model, hypothetical populations were composed of five different life histories, which were genetically determined. Each life history type had its own rate of survival and...

Creator:: Pongthana, Nuanmanee
Abstract:: Two replications of a half dial lei cross experiment were performed among four inbred lines of mosquitofish, Gambusia affinis. These inbred lines originated from three random-bred stocks: OR, TX and CD. The experiment was conducted as a completely randomized design. Experimental material consisted of parental lines and F₁ populations maintained...

Creator:: Doverspike, Mark Steven
Abstract:: Eutrophication is the accelerated aging process of a lake which generally decreases the water quality in terms of aesthetic and recreational uses. At Liberty Lake, near Spokane, Washington, eutrophication has become a problem. Many individuals and agencies are interested in the benefits that occur when the lake's water quality has...
