The juvenile demersal fish assemblage along the Pacific Northwest coast has received little attention relative to adult life history stages since pioneering work in the 1970s. Increasing severity of hypoxia along the Oregon coast in recent years has prompted investigations into the response of biota in this region. We used...
Over the last several years, the Northwest Fisheries Science Center, in collaboration with the Pacific States Marine Fisheries Commission and Oregon State University, has been sampling young-of-the-year groundfishes and other small demersal fishes along the Newport Hydrographic (NH) line. An important question concerning these surveys is whether the NH line...
Various ocean-climate models driven by increased
greenhouse gases and higher temperatures predict a
decline in oceanic dissolved oxygen (DO) as a result
of greater stratification, reduced ventilation below the
thermocline, and decreased solubility at higher temperatures.
Since spreading of low oxygen waters is
underway and predicted to increase, understanding
We examined the feasibility of using a video beam
trawl system to assess behavioral responses of juvenile
flatfishes in relation to co-occurring habitat features,
most notably dissolved oxygen (DO) concentrations. Sixteen
samples were collected along a cross shelf transect in
the central Oregon coast during summer 2008. We found
