Whitebark pine (Pinus albicaulis Engelm.) tree-ring chronologies of 700 to greater than 1,000 years in length were developed for four sites in the Sawtooth-Salmon River region, central Idaho. These ring-width chronologies are used to (1) assess the dendrochronological characteristics of this species, (2) detect annual mortality dates of whitebark pine attributed to a widespread mountain pine beetle (Dendroctonus ponderosae Hopk.) epidemic during the 1909 to 1940 period, and (3) establish the res...

Atlantic salmon (Salmo salar Linn.) have been known to inhabit the rivers flowing north into Ungava Bay for many years. In spite of their importance no biological investigation of the populations has previously been carried out. These populations are of particular interest as it is here that the salmon reaches the most northerly extent of its range in eastern Canada. [...]

Salmon farmers face an uncertain production environment and considerable price volatility, making planning a vital success criteria. This thesis describes the sources of uncertainty that are most important when planning sales, and demonstrates how this uncertainty can be taken into consideration by the use of stochastic programming.The basis for this thesis is the tactical planning problem of deciding when to harvest salmon and how to allocate sales between available contracts and sales in the s...

Estuarine residence and growth of juvenile chum salmon (Oncorhynchus keta) from Netarts Bay, Oregon were estimated from daily-formed growth increments of sagittal otoliths which are distinguishable from accretion patterns formed during freshwater residence. Estuarine residence time was inversely related to the average size at which juvenile chum salmon entered Netarts Bay. Among fin-clipped, hatchery fish, large individuals disappeared from Netarts Bay more rapidly than smaller members of the sa...

Policy decisions in fishery management are becoming increasingly complex and difficult. This is especially true for the salmon fisheries where policy outcomes affect the productivity of the salmon resource and the subsequent well-being of commercial fishermen, charter boat operators, Indian fishermen, and sport anglers. The objective of this study was to advance methodology from statistical decision analysis which would assist fishery managers in Oregon who must make particularly difficult choic...

The fundamental objective of this analysis was to isolate and identify the factors governing the demand for domestically produced rainbow trout in a representative west coast market, and assess the impact on that demand, if any, of the introduction of pansize salmon. The approach taken in this market demand study was to identify those variables hypothesized to determine supply and demand for rainbow trout. Several testable hypotheses concerning the anticipated relationships were specified. It wa...

The spawning habitat associated with fall chinook salmon (Oncorhynchus tshawytscha) redd clusters was investigated in the Hanford Reach of the Columbia River. A conceptual spawning habitat model is proposed that describes how geomorphic features of river channels create hydraulic processes, including hyporheic flows, that influence where salmon spawn in unconstrained reaches of large mainstem alluvial rivers. Spatial point pattern analysis of redds showed that redd clusters averaged approximatel...

An approach to understanding and managing anadromous salmon, steelhead, and sea-run cutthroat trout (Oncorhynchus spp.) based on life history and evolutionary adaptive capacities of species and stocks is presented. Species, stocks, and local populations are viewed as systems that are continuously adapting to changing environmental conditions. They have the potential capacity to evolve in different ways in different environments through both life history and evolutionary adaptation. Habitat organ...

Stocks of salmon are declining in the Pacific Northwest. Based on region-wide studies that list and categorize the status of salmon stocks (Nehlsen et al., 1991; Huntington et al., 1994; and Nawa, 1995), I analyze the watersheds where stocks of salmon spawn for several anthropogenic variables, most of which are known to affect salmon. A total of 202 watersheds (stocks of salmon) in Washington, Oregon, California, and Idaho are coded for 13 anthropogenic variables such as dams, forest, agricultur...

This paper provides probit estimates of willingness to pay for Snake River salmon recovery projects using the contingent value survey method. Two types of survey method are tested, the direct question format and the randomized response format. Additionally, both an increase in electric bill payments and volunteer time are offered as payment vehicles. The results suggest that there is not much difference in estimates of willingness to pay between the two survey formats. They also suggest that for...

Various aspects of the energetic response to handling stress in juvenile coho salmon (Oncorhynchus kisutch) were examined. Fish were subjected to four different handling stressors in a Blazka-style respirometer. Stressed fish had rates of oxygen consumption that were higher than controls. The magnitude of the increase ranged from 139 to 198% of the control value, and appeared roughly related to the severity of the stressor. The post-stress increase in oxygen consumption also appeared to vary sea...

Dietary proteins from Atlantic salmon and cod have previously been shown to have antidiabetic effects. Since dietary proteins are digested into small peptides before being absorbed through the intestinal mucosa, it is reasonable to deduce that the antidiabetic effect is due to enzymatically-digested peptides rather than the proteins themselves. The aim of this study was to develop a protocol to recover peptides with antidiabetic effects from salmon and cod protein digests and then scale up and o...

The research involved development of two ecological simulation models to explain the complex dimensionality of chinook salmon (Oncorhynchus tshawytscha) life history structure (represented by the age composition of the spawning stock) and management difficulties entailed in the complexity. Since different sizes of chinook salmon are thought to adapt differently to heterogeneous habitats, age composition of the spawning stock is determined by characteristics of the habitats of the substocks. Nume...

This study investigated smoltification and seawater adaptability of sockeye (Oncorhynchus nerka) and quinnat salmon (O. tshawytscha). Both species were introduced into New Zealand with an anadromous population of quinnat and a totally freshwater population of sockeye salmon becoming established. The sockeye were found to be capable of successfully adapting to sea water and appeared not to have lost their hypoosmoregulatory ability despite being landlocked for approximately 90 years. The physiol...

Large-scale expressed sequence tags (ESTs) in Atlantic salmon (Salmo salar) are examined to answer questions regarding salmonid transcriptomes. ESTs represent raw and incomplete gene sequences that need to be read, assembled and analyzed with computer software. The goal of this thesis was to develop an automatically curated and publicly accessible set of annotated full-length genes, representing a near-complete transcript set for Salmo salar. In turn, these genes provide the framework for studie...

Wild salmon face an alarming decline in numbers around the globe due to various reasons from which a great part serves the decrease of water quality and habitat destruction. Keeping in mind the benefits associated with wild salmon new measures and forms of social involvement are urgent before it becomes impossible to safeguard the species of interest. Followed by the international recommendations this study supported the use of a bottom-up working approach taking into account public opinion. A s...

Mechanisms and the energetic implications of osmoregulation were investigated in the early life stages of chum (Oncorhynchus keta) and coho salmon (O. kisutch) at three different developmental stages: eyed embryo, prehatch embryo, and yolk sac larva. Embryos and larvae were acclimated (>7 d) to selected ranges of saltwater (SW) concentrations (0 to 30 %oS) in order to examine whole-animal (Chapter 1), cellular (Chapter 2), and biochemical (Chapter 3) aspects of early life osmoregulation Ch...

Adult Pacific salmon (Oncorhynchus spp.) are targeted by the recreational, commercial, and First Nations fisheries during their spawning migrations through the Fraser River, British Columbia, Canada. Salmon can escape from each fishery or be released either voluntarily or due to mandate. Despite a high proportion of Pacific salmon released from each fishery, the primary (e.g., catecholamine, corticosteroid), secondary (e.g., metabolic, osmoregulatory, cellular), and tertiary (e.g., behavioural, ...

This thesis focuses on the classic problem of investment per offspring. It is an attempt to (i) reconcile theoretical research with empirical methods that can be used to test theory, (ii) test a fundamental prediction that arises from classic theory, and (iii) test one of the more recent theoretical developments. We use Atlantic salmon (Salmo salar) as a model organism. Drawing from the classic Smith–Fretwell model, we provide defensible definitions of offspring fitness that can be used in empir...

Rapid advances in the aquaculture industry pose an environmental challenge that is generated by outbreeding between escaped domesticated and wild individuals. Given that escapees genetically differ from wild individuals because of domestication and possibly by ancestry, periodic domesticated-wild outbreeding has the potential to influence fitness-related traits in wild populations. In Atlantic salmon (Salmo salar), the understanding of mechanisms and direction of domesticated influences are espe...

The sea louse, Lepeophtheirus salmonis, has been hypothesized to be a vector of fish pathogens and previous studies have isolated viral and bacterial pathogens from L. salmonis parasitizing farmed salmon. To examine the potential transmission of A. salmonicida by preadult and adult L. salmonis via parasitism of Atlantic salmon (Salmo salar), an in vivo bacteria-parasite challenge model was tested. Two pathogen challenge trials were performed, in which sea lice from donor (Aeromonas salmonicida-i...

Juvenile coho (Oncorhynchus kisutch) will spawn and have their offspring reared in very different habitat types in coastal British Columbian streams. For instance, some utilize main channel river areas whereas others take advantage of off-channel habitats. However, during winter, juveniles produced in the main channel areas are believed to move into off-channel habitats for reasons of protection. These main channel juveniles tend to be much larger at the start of winter than the off-channel...

Genetic manipulation is widely used for the improvement of agricultural organisms. However, alterations of the genome could also result in unintentional changes, and could perhaps alter the performance of the organism. Performance traits such as sensitivity to stressors and to pathogens are strongly influenced by genetic information, and could therefore be affected by alterations of the genome. In this thesis, I tested the hypothesis that genetic manipulation alters the stress response and ...

During the salmon can-filling process, a number of can-filling defects can result from the incorrect insertion of the salmon meat into the cans. These can-filling defects must be repaired before sealing the cans. Thus, in the existing industrial process, every can is manually inspected to identify the defective cans. This thesis details a research project on the use of machine vision for the inspection of filled cans of salmon. The types of can-filling defects were identified and defined th...
