Lingcod (Ophiodon elongatus) are known to utilize certain estuaries along the Pacific coast of the United States, but the importance of these habitats to the coast-wide population is not well understood. In this study, general patterns of estuarine habitat use were assessed by tracking the movement of sub-adult and adult...
Over fishing, by-catch of non-target fish species, marine mammals, seabirds, and damage to benthic habitats remain serious problems in fisheries management. Management methods based on traditional command and control (CAC) approaches may meet with initial successes yet additional progress is often marginal, requiring managers to implement additional regulations to achieve...
Cooperative marine fisheries research—the practice of involving the expertise of fishermen and scientists in conducting studies of ocean fishes—has increased gradually over the past 50 years on the US west coast. However, few studies have systematically collected and analyzed the experiences and perceptions of numerous cooperative marine fisheries research project...
As competing uses of our coastlines increase, natural resource agencies are employing marine spatial planning (MSP) to designate areas for different uses or activities in order to reduce conflicts while achieving ecological, economic and social objectives. A central challenge of implementing MSP is development of a rigorous approach for analyzing...
The purpose of this research was to explore the impact of finfish bycatch on the ocean shrimp Pandalus jordani fishery using two methods. One method looked at the breakage of the shrimp by finfish bycatch in the nets. The other looked at the impact of bycatch on fishing decisions. At-sea...
The purpose of this study was to develop and evaluate a nutrition
education program for men on healthy eating when dining out. The
Health Belief Model provided the basic framework to identify factors that
would potentially motivate men over 40 to change their dietary behavior
to reduce heart disease risk....
Salmon restoration has become a major priority in the Pacific Northwest. In the State of Oregon, much of
the responsibility for habitat restoration has fallen on local watershed councils, with the majority of their
funding coming from state and federal grants. Funding limitations, including the amount of funds allotted
to...
A structural model of the Pacific halibut fishery is developed. Hypothesis tests
are developed within the framework of the "new empirical industry organization" for
the exertion of market power by Pacific halibut processors in both the exvessel market
and the wholesale market. The relationship of market power exertion and IPHC's...
Quantitative assessments of many West coast rockfish stocks of both major and
minor importance to commercial fisheries have shown varying declines in abundances. The population sizes of less-abundant, co-occurring unassessed species may also be
declining. However, determining stock status of the many non-targeted, minor species with high levels of certainty...
An acceptable microparticulate diet for marine fish larvae may be defined as an artificial diet that contains, retains, and delivers the required nutrients to support survival and growth. Factors affecting ingestion rate of prey items by fish larvae include environmental factors such as light intensity, prey/background contrast, possible chemical cues,...
