Distribution and life history of the spiny dogfish (Squalus acanthias) off the Oregon and Washington coasts

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...

Growth rates and species composition of juvenile rockfish (Sebastes spp.) in Oregon’s nearshore and estuarine habitats

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...

The Influence of Riparian Habitat and Microhabitat Selection on Fish Assemblaqe Structure in the Upper John Day Basin, Oreqon

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...
