  Citation × Citation Citation Abstract Copy Title: A demand analysis of processed salmon from the West Coast Author: Wood, William Robert 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, and the Pacific Fisherman. Ordinary least squares using the wholesale price as the dependent variable in the demand equation was the principal method of analysis. Coefficients for the demand expressed flexibilities with respect to the price. Price flexibilities calculated at the mean values for all processed salmon indicated that a ten percent increase in volume would reduce price by a lesser percentage. For increases in the supply of processed salmon, total revenues would increase, where decreases in supply would cause total revenues to decline. The results of the study also indicated that for a small percentage increase in disposable income, prices would increase but by a lesser percentage. Inverse relationships were noted between the price of salmon and the quantity of canned meat and meat products. Effects of population changes on the price of processed salmon were inconclusive.

  Citation × Citation Citation Abstract Copy Title: When Celilo was Celilo : an analysis of salmon use during the past 11,000 years in the Columbia Plateau Author: Thomison, Patrick The presence and significance of salmon for prehistoric and aboriginal people of the Columbia Plateau is a matter of considerable debate among anthropologists, archaeologists and historians. Data from over 100 archaeological sites are scrutinized in the light of an example salmon fishery developed from ethnographic and archaeological information on aboriginal salmon dependencies and exploitation in the locale of The Dalles on the central Columbia. The research incorporates a cultural ecology orientation. Data from prehistoric sites of the Columbia Plateau do not conform precisely to The Dalles fishery example and strongly suggest both a temporal and spatial variation in salmon use and cultural patterning and therefore call to question the presumption of the primary relevancy of salmon to cultural patterning throughout the Plateau. Other resources, including especially botanical species, appear to have an importance too often overlooked. Other riverine and terrestrial mammal food resources are presumed to have a lesser prehistoric importance, though the archaeological record actually supports the importance of resources other than salmon as having pervasive affects on cultural patterning in the Columbia Plateau. Data show that it was not until recent times that salmon occurrence had the effect on cultural systems that has been observed in historic times.

  Citation × Citation Citation Abstract Copy Title: The effects of single and multiple pathogen and parasite infections on juvenile chinook and coho salmon during early marine residency Author: Sandell, Todd A. Nearly 3000 juvenile Chinook (Oncorhynchus tshawytscha) and coho (O. kisutch) salmon captured in nearshore waters off the coasts of Washington and Oregon from 1999-2004 were tested for infection by Renibacterium salmoninarum, Nanophyetus salmincola, and skin metacercariae. First, three quantitative PCR primer/probe sets were compared for detection of R. salmoninarum; amplification of the single copy abc gene was best at detecting medium-high levels of infection and was used in subsequent studies. Parasite infections were detected visually. Infection by N. salmincola was the most common single infection among all juvenile salmon (55.2%), followed by R. salmoninarum (27.5%) and skin metacercariae (16.5%). Infection by R. salmoninarum was highest in 2000, with 54.8% of all juvenile salmon infected, and was much lower in 2004 (<10%). Subyearling (but not yearling) Chinook salmon infected by N. salmincola had significantly reduced growth; skin metacercarial infection was associated with significantly reduced growth only for coho salmon. Infection by R. salmoninarum was associated with significantly reduced growth in yearling Chinook salmon and coho salmon. Multiple infections did not have significantly more severe effects on growth than single infections, although the prevalence of triple infections was very low. The prevalence of R. salmoninarum was significantly and positively correlated with increased survival for both yearling Chinook and coho salmon. To better understand the apparent paradox that higher prevalences correlate with increased survival, we examined the effects of ocean conditions using the summer Pacific Decadal Oscillation (PDO) index as an indicator of good (cold) or bad (warm) ocean condition years. The years 1999-2002 were cold ocean years, and 2003-2004 were warm ocean years. The prevalence of R. salmoninarum was significantly higher in cold years, when ocean conditions were favorable, and more salmon with severe infections were captured; there was no effect of infection on growth. In the summers of warm years, infected yearling Chinook and coho salmon had significantly reduced growth, and the prevalence and severity of R. salmoninarum infections declined. These data indicate that the infection is less detrimental in years with favorable ocean conditions, and suggest that R. salmoninarum infection may be a mechanism linking ocean indices to salmon survival.

  Citation × Citation Citation Abstract Copy Title: Stream habitat utilization and behavior of sympatric and allopatric wild cutthroat trout (Salmo clarki) and hatchery coho salmon (Oncorhynchus kitsutch) Author: Jacobs, Steven Edward The behavior and stream habitat utilization of juvenile hatchery-reared coho salmon (Ovicozihynchus kisutch) and wild cutthroat trout (Salmo clarki) were examined to assess the nature of interactions between the species potentially resulting from introductions of hatchery coho salmon in streams. Habitat utilization was monitored in Mill Creek, Polk Co., Oregon by manipulating the composition of fish within three study sections to include either allopatric or sympatric populations of hatchery coho salmon and wild cutthroat trout. In allopatry, coho salmon and cutthroat trout selected feeding microhabitat that was similar in physical characteristics and exhibited extensive dietary overlap. When the two species occurred in sympatry, feeding microhabitat used by coho salmon was altered, however, that of cutthroat trout was comparable to allopatric cutthroat trout. No discernable differences in dietary composition between allopatric and sympatric fish were detected. While allopatric cutthroat trout always gained mass. ailopatric coho salmon always lost mass. Stomach fullness indices were higher for allopatric cutthroat trout than allopatric coho salmon. Sympatric cutthroat trout had comparable or greater gains of mass, indices of stomach fullness, and hepatic glycogen reserves relative to allopatric cutthroat trout. Conversely, sympatric coho salmon had greater losses of mass, reduced hepatic glycogen reserves, and apparently lower indices of stomach fullness than allopatric salmon. Behavioral observations made through the use of an in-stream viewing chamber in Berry Creek, Benton Co., Oregon, indicated that in allopatry populations of hatchery coho salmon and wild cutthroat trout were structured as linear dominance hierarchies that were organized by quantitatively and qualitatively similar aggressive interactions. In sympatry, however, cutthroat trout were more aggressive and socially dominant to coho salmon. The shift in use of micro-habitat and reduction in habitat utilization effectiveness of hatchery coho salmon in the presence of cutthroat trout can, thus, be interpreted to occur as a result of interference competition mediated through interspecific aggression.
