This study examines the relationship between fishing activities
of Pacific Northwest albacore fishermen and the availability of albacore.
Tactical responses of troll-boat fishermen were compared to
changes in daily apparent albacore abundance. Tactical responses
included boat aggregation and total applied effort (number of boats)
within a particular area, and net...
The nearshore zone at Newport, Oregon was studied during the
period September, 1968 to August, 1969. Particular emphasis was
placed on those physical factors affecting the distribution of pulp mill
wastes discharged within the study area (referred to as Yaquina Bight
in this thesis). Temperatures and seawater samples were obtained...
Catch data for albacore troll boats were collected from fishermen's logbooks and from dockside
interviews during the 1968, 1969, and 1970 seasons. Fishing powers of these boats were calculated and used to determine the 10 most successful and 10 least successful fishermen (highliners and lowliners, respectively) who fished off Oregon...
The purpose of this study is to examine the hypothesis that diel variations occur in the catches of albacore by boats trolling surface jigs off Oregon. Although albacore fishermen talk of "morning bites" and "evening bites," no published data exist, to our knowledge, confirming these trends.

of the Benders decomposition procedure, combined with a linear
mixed integer programming (MIP) algorithm specifically designed to
solve the problem associated with Benders...
The purpose of this study is to review Pennsylvania's
use of paper money through two distinct periods: the first
seven years of currency issues starting in 1723 and
concluding in 1730, and the second period encompassed by
the French and Indian War in 1755-63. They represent two
significant periods affecting...
Freshwater systems cycle carbon along a spatial and temporal biogeochemical continuum, across which ecosystem processes contribute to transformations of organic matter (OM). Various ecological constraints impact rates OM transformation and production and consumption of the energetic end of respiration, methane. Microbiological processing and complete reduction of carbon substrates to methane...
A rapid expansion of population and industrialization in recent
years has created new and difficult problems in water resources
management. Prudent management of water quality will require that
more efficient methods be developed for evaluating large volumes of
data on complex river systems, and tabulating the results in a form...
Since the early 1950's, the distribution of sediment at the
mouth of Redwood Creek has been altered by the effects of channel
aggradation and channelization along the lower reach. Severe flooding
in 1953, 1955, and 1964 caused bank erosion, landsliding, and
channel geometry changes along Redwood Creek. The increased sediment...
Fishing firms in Oregon operate in a complex and dynamic physical, biological and institutional environment. Within this environment, managers of these firms will attempt to maximize some objective function which may include profit. This maximization is dependent upon the level of output, or the levels of inputs. Given a relationship...
