Cathepsins are intracellular proteinases that hydrolyze the peptide bonds of proteins. These enzyme have been implicated in the tenderization of aging beef, with the deterioration of radiation-stabilized meats on storage, and in the spoilage of fish prior to processing. Hence, the cathepsins of edible muscles are of concern to the food scientist. The purpose of the research reported herein was to develop procedures for the purification of the cathepsin from salmon muscle. The availability of a p...

The primary purpose of the study was to identify the demand for processed salmon from the West Coast. The basic approach in the demand analysis was to identify those variables that determine the supply and demand for processed salmon. An econometric model was established containing the supply and demand equations from which estimates for the parameters in each equation were obtained. The main source of data for salmon was obtained from publications printed by the Bureau of Commercial Fisheries, ...

The primary purpose of this study is to investigate the salmon demand of Japanese households. The specific goals are to illuminate the substitutional relationship between salmon and other foods and to examine seasonal and regional differences in salmon demand. To analyze substitutional relationships and seasonal differences, monthly data on consumption by Japanese households are used. An econometric model was developed in which salmon demand was specified with quantity of salmon consumed as the ...

The primary objective of this study was to identify and investigate the underlying basis for variation in the volume of exports of Canadian chum salmon during 1954-1975 period. A number of factors thought to be of importance in the determination of the volume of exports of chum salmon were hypothesized. These factors were: chum salmon price» the price of substitute commodities, the consumer income, population, general price level in importing countries, and fluctuations in exchange rates between...

The aim of this thesis was to evaluate the potential of using sperm cells as a vector for gene transfer in chinook salmon (Oncorhynchus tshawytscha). Preliminary studies indicated that while salmon sperm were inefficient at picking up DNA during simple incubation, electroporation of the sperm significantly enhanced the sperm/DNA association. Therefore, a number of factors were examined to identify the optimal conditions for DNA uptake by salmon sperm and the subsequent transfer of foreign DNA in...

The parr-smolt transformation is a life-history strategy that has evolved in salmon to prepare migratory juveniles for oceanic survival. A necessary adjustment for homeostasis is an increase in the uptake of fluid by the intestine, which will continuously replace the loss of body water in a salty environment. Vertebrate corticosteroids regulate hydromineral balance. Cortisol mediates adaptive changes in fish intestine, but much remains to be learned about the sites of action and participation of...

Eight scale characters of known hatchery and wild coho salmon (Oncorhynchus kisutch) were compared, and a linear discriminant function was used to determine if hatchery and wild adult coho salmon could be correctly identified by their scales. Eighty-two percent of the hatchery and 89% of the wild fish were correctly identified. Based on analysis of scales from adult salmon of unknown origin (hatchery or wild) and the estimated catch of hatchery coho (marked) taken by the Oregon sport fishery, co...

Sockeye salmon (Oncorhynchus nerka) in the Fraser River are immensely important to British Columbia's culture and economy. Despite centuries of exploitation and decades of intensive study there remain several key uncertainties about the biological system, including those around dramatic four-year cycles of abundance and pre-season projections of how many fish will return in a given year. Recent years have seen declines in the productivity of some stocks as well as broader conservation concerns, ...

Morien, Evan

Declines in Pacific salmon stocks in recent decades have spurred much research into their physiology and survivorship, but comparatively little into their genomics. Sockeye salmon in particular are experiencing high levels of mortality during their migration upriver, and the numbers of returning sockeye have fluxuated wildly with respect to predictions in recent years. The goal of my project is to gain insight into the basic genomics of Pacific salmon stocks, including the sockeye, through bioin...

Investigating the role of natural selection in driving adaptive diversification has become a central theme in evolutionary ecology as advancements in genome typing technologies provide new approaches for identifying the genetic basis of phenotypic diversity in non-model organisms. I used population-based genome scans to investigate the recent divergence of shore- and stream-spawning ecotypes in Kokanee salmon (Oncorhynchus nerka). These ecotypes co-exist in many post-glacial lakes throughout t...

This thesis explores the role for social work in addressing government policies that threaten the sustainability of small coastal communities. The response of government and industry to the globalization of trade and resource degradation is at odds with the needs of people. Utilizing a case study methodology the development and implementation of the Pacific Salmon Revitalization Plan is explored. This department of fisheries plan to rationalize the fishery was highly contested on the ground...

Three numerical models were used to investigate whether compass orientation is an effective guidance mechanism for sockeye salmon migrating to the Fraser River from the open ocean. Daily surface ocean currents, simulated by the Ocean Surface Currents Simulations (OSCURS) model, were used in each model to test the influence of currents on the return oceanic migration of the Fraser River sockeye salmon. The high seas tagging and coastal recovery data of the Fraser River sockeye salmon were us...

It has now been widely shown that the genetic mating system of an organism determined using genetic markers can be very different to the social mating system based on behavioural observations. However, it is less well known what particular characteristics make an individual more or less successful than expected from the observed system. I present the first attempt to measure individual genetic reproductive success, as evidenced by microsatellite parentage assignment, and to compare this measure ...

In this thesis I studied factors that influence reproductive success in two age classes of male sockeye salmon (Oncorhynchus nerka). In my first experiment I tested for the presence of frequency-dependent reproductive success of male age classes in single spawning events and examined the influence of the number of males present on frequency-dependence. I placed groups of males in an enclosure with a nesting female, allowed them to spawn, and determined paternity of the resulting offspring. ...

Atlantic salmon (Salmo salar) skin was hydrolyzed separately with three different enzymes, trypsin, α-chymotrypsin and papain, for two different times (2 and 4 h). The crude hydrolysates and unhydrolyzed soluble skin proteins were screened for antioxidant, antimicrobial and trypsin inhibitory properties. The antioxidant tests used, - namely, DPPH radical scavenging, metal chelation and reducing power assays, - showed that all hydrolysates and soluble proteins at 2mg/ml possessed antioxidant prop...

Both field and laboratory experiments have shown lethal effects from the deposition of silt on incubating salmon eggs. Because silting appears to deprive the eggs of sufficient oxygen, theoretical limits of flow and oxygen content of sub-surface water were studied. Data have been gathered on temperature, oxygen content, and rate of flow of water twelve inches below the surface of the gravel at Nile creek. Field determinations of oxygen consumption of pink, chum and coho eggs have been made. In h...

Chum salmon embryonal discs were smeared and the cells stained with acetocarmine (60° C.) for chromosome content. Thirty-eight chromosomes (granular, sigmoid, and j-shaped) were counted, but the number was not considered absolute. The presence of sex chromosomes could not be established. Chromosomes in cells of differentiating gonads showed such excessive clumping that a count could not be made. Sex differentiation was followed in chum salmon. Sections from alevins (three weeks old) showed th...

Although the first preparations of the hypocalcemic hormone, calcitonin (ct), were extracted from rat thyroid glands, histological evidence showed that the "c" cells which produce the hormone are not restricted to this gland, but also occur in the parathyroid and thymus tissues of mammals. These cells arise embryologically from the last branchial pouch and in non-mammals they form a separate ultimobranchial gland which also contains hypocalcemic activity. The work described in this thesis provid...

The Atlantic salmon depend on successful migration between essential habitats in freshwater and the ocean. However, during both downstream and upstream migration the fish encounter natural or manmade obstacles which can block or delay their migration and migration through hydropower turbine can cause severe mortality. This PhD-study has focused the salmon migration challenges, upstream and downstream, based on studies in Norwegian rivers, and the results are presented in four scientific papers. ...

Total energy expenditures and muscle activity have been measured in spawning salmon but behaviour specific energy-use has never been been measured directly. This research used electromyogram (EMG) telemetry, combined with behaviour observations to assess activity levels and estimate relative energy use during spawning in sockeye salmon, Oncorhynchus nerka. My main objectives were to: assess the ability of EMG transmitter technology to discriminate between the rate of muscle activity during...

Divergent natural selection across a heterogeneous landscape can drive the evolution of locally adapted populations in which phenotypic variation is fine-tuned to the environment. At the molecular level, such processes can be inferred by identifying correlations between genetic variation and environmental variables. In this dissertation, I used multiple complementary approaches to investigate the genetic basis of adaptation in natural populations of kokanee, the freshwater form of sockeye salmon...

The development of a radioimmunoassay for salmon calcitonin is described. Synthetic salmon calcitonin was iodinated with I(125) and used as tracer. The coated charcoal method, suitably modified, was employed to separate bound and free salmon calcitonin. Antisera were raised by intradermal and intramuscular injection of calcitonin conjugated to keyhole limpet hemocyanin with carbodiimide. The sensitivity of the assay is 50 - 60 pg/ml of incubate. The disappearance of synthetic salmon calcitonin i...

The reason for this story was to investigate a narrative that is important to the identity of North America’s Pacific Northwest Coast – a narrative that revolves around wild salmon, a narrative that always seemed too simple to me, a narrative that gives salmon a mythical status, and yet what does the average person know about this fish other than it floods grocery stores in fall and tastes good. How do we know this fish that supposedly defines the natural world of this place? I began my resea...

Cross-habitat subsidies of nutrients and prey can structure community processes in receiving ecosystems. Every autumn throughout the northern Pacific region, anadromous salmon (Oncorhynchus spp.) return to their natal watersheds to spawn and die. a landward migration that imports marine protein to estuarine, freshwater and terrestrial habitats. Spawning salmon regulate the population dynamics of many wildlife species and fertilize aquatic and terrestrial systems with their nutrients and carcasse...
