Marine protected areas (MPAs), ideally, manage human uses that threaten ecosystems, or components of ecosystems. During several recent MPA designation processes, concerns have arisen over the scientific justification for no-take MPAs, particularly those that restrict recreational fishing for pelagic species. An important question is: under what conditions might recreational pelagic...
Dramatic changes in the physical and biological conditions off Washington and Oregon, USA, have occurred since 1998, including extreme El Niño (warm) and La Niña (cool) years, high and low Columbia River flow years, a major intrusion of subarctic water, and a low oxygen event on the shelf. The occurrence...
The problem of extinction in the sea has been recognized
only recently by the scientific community (Roberts and
Hawkins 1999). For the last decade, the American Fisheries
Society (AFS) has pursued an initiative to identify marine
fish stocks that may be at risk of extinction in North America
(Musick 1998;...
"The MSC was created through the impetus of three needs. Wayne Burt of the newly formed Oceanography Department needed dock and ship support facilities for his NSF-funded research vessel on the coast. Roland Dimick of the Fisheries and Wildlife Department needed to expand his small bay research lab located at...
Larval and age-0 sablefish Anoplopoma fimbria reside in neustonic waters of the North Pacific during spring and summer. We estimated the potential impacts of elevated surface temperatures on ecological processes of growth, conversion efficiency, and behavior in early juvenile sablefish. Growth experiments tested a wide range of temperatures from 6...
The goal of this study was to describe the duration and magnitude of the physiological stress response in lingcod Ophiodon elongatus after exposure to brief handling and sublethal air stressors. The response to these stressors was determined during a 24‐h recovery period by measuring concentrations of plasma cortisol, lactate, glucose,...
A critical seasonal event for anadromous Chinook salmon (Oncorhynchus tshawytscha) is the time at which adults migrate from the ocean to breed in freshwater. We investigated whether allelic variation at the circadian rhythm genes, OtsClock1a and OtsClock1b, underlies genetic control of migration timing among 42 populations in North America. We...
There are several assumptions regarding the behavior and motivations of participants in fishery management that may hinder the effectiveness of the management process. In this research, we examine whether the commercial fishing industry is a homogeneous group whose decision-making is dominated by short-term economic considerations to the detriment of long-term...
