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 that...
Environmental variability is increasingly recognized as a primary determinant of year-class strength of marine fishes by directly or indirectly influencing egg and larval development, growth, and survival. Here we examined the role of annual water temperature variability in determining when and where walleye pollock (Theragra chalcogramma) spawn in the eastern...
Pacific cod (Gadus macrocephalus) is an important component of fisheries and food webs in the North Pacific Ocean and Bering Sea. However, vital rates of early life stages of this species have yet to be described in detail. We determined the thermal sensitivity of growth rates of embryos, pref lexion...

Abundances of larval walleye pollock in Shelikof Strait, Gulf of Alaska, in 1981 were far
greater than any recorded estimates before that time or since (some patch estimates exceeded 100000
larvae per 10 m²). In spite of this extraordinary input, the ensuing 1981 year class was relatively poor.
An examination...
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...
Understanding responses of marine species to temperature variability is essential
to predict impacts of future climate change in the oceans. Most ectotherms are
expected to adjust their behavior to avoid extreme temperatures and minimize
acute changes in body temperature. However, measuring such behavioral plasticity
in the wild is challenging. Combining...

Behavioral responses of Atlantic cod to sea temperature
For many organisms, the reconstruction of source-sink dynamics is hampered by limited knowledge of the spatial
assemblage of either the source or sink components or lack of information on the strength of the linkage for any source-sink
pair. In the case of marine species with a pelagic dispersal phase, these...
