Creator:: Richards, Jaclyn M.
Abstract:: This study examines the spatial and temporal distribution and life history of the "offshore" component of the Northeastern Pacific spiny dogfish (Squalus acanthias) population. Distribution was examined in relation to latitude, depth, the Columbia River plume and large-scale climate changes. Fishery and survey data indicate that the Northeastern Pacific spiny...

Creator:: Alexander, Susan J.
Abstract:: A random utility model of trip demand for steelhead fishing is constructed by using a logit regression technique and data from the 1990 Oregon Angler Survey, conducted by the Oregon Department of Fish and Wildlife. The model is formulated to estimate demand when only the regional destination is known. Results...

Creator:: Gallagher, M. Brett
Abstract:: Identification of critical habitat for all life stages of commercially exploited fish populations is critical for effective management. Despite a clear need for basic biological information on juvenile rockfish life history, there have been very few efforts to describe distribution and habitat of this life stage, particularly along the Oregon...

Creator:: Ottmann Riera, Daniel
Abstract:: Most benthic marine organisms have a bipartite life with an early pelagic stage that enables dispersal of offspring, connecting spatially separated populations, and a late stage where individuals reside in a benthic habitat. Settlement of pelagic offspring to bottom associated substrates is the process that connects the two life history...

Creator:: Leitzinger, Eric J.
Abstract:: Fish assemblage structure was determined along a longitudinal gradient for three drainages in the upper John Day basin: Middle Fork, South Fork, and upper Mainstem proper. One or two tributaries in each drainage were included. Where possible, sites were paired: those with good versus those with poor riparian habitat. Detrended...

Creator:: Petersen, Robin S.
Abstract:: Pacific lamprey (Lampetra tridentata) have historically been considered by the Western scientific community as a "trash" fish and generally overlooked in West Coast fisheries management. Recent population declines in Pacific Northwest streams have triggered new research to understand the life history and ecological significance of this species. These new studies...
