Distribution, Abundance, and Settlement of Slope-spawning Flatfish during Early Life Stages in the Eastern Bering Sea

Creator:: Sohn, Dongwha
Abstract:: Changes in environmental conditions in marine ecosystems could directly or indirectly influence distribution, abundance, settlement, and size at settlement of flatfish. Understanding species-specific and age-specific responses to environmental variability is important for managing commercially important flatfish stocks. Slope-spawning flatfish whose offspring rely on extensive drift from the slope (spawning) to...

Variation in the energy density of forage fishes and invertebrates from the southeastern Bering Sea

Creator:: Whitman, Luke D.
Abstract:: The quality and availability of forage fishes and invertebrates can affect the behavior and productivity of predators that rely on these resources. This study measures the proximate composition of forage fishes and invertebrates from the southeastern Bering Sea to estimate prey energy density (quality) using a method that is ecologically...

The Responses of Slope-spawning Flatfish to Environmental Variability in the Eastern Bering Sea

Creator:: Vestfals, Cathleen D.
Abstract:: When adult spawning and juvenile settling locations of marine fishes are geographically separated, their early life history stages must rely on transport and their own behavior to move them toward suitable habitats for successful recruitment to the juvenile phase. Variations in climate may reduce the availability of spawning and juvenile...

Horizontal and vertical distribution of juvenile pollock (Theragra chalcogramma) in the southeastern Bering Sea

Creator:: McIntosh, Neal E.
Abstract:: Juvenile walleye pollock (Theragra chalcogramma) are one of the primary prey items for bird and mammal predators in the Bering Sea and support a large commercial fishery. An understanding of the environmental factors that determine the horizontal and vertical distribution of juvenile pollock is needed to estimate the effects that...

Using auklets to monitor the effects of global warming on the Bering Sea ecosystem : Detecting change in auklet food supply, productivity, and populations

Creator:: Sheffield, Lisa M.
Abstract:: Global warming is progressing more rapidly in polar-regions, and its effects are more pronounced at high latitudes than in other parts of the globe. Changing ocean conditions due to climate change are predicted to have dramatic impacts on marine foodwebs. Seabirds, as upper trophic-level consumers, provide a highly visible and...

Implementation of a gross anatomical maturity key for the study of spawning phenology and geography of Pacific cod (Gadus macrocephalus)

Creator:: Neidetcher, Sandra
Abstract:: Pacific cod (Gadus macrocephalus) is an important species, both economically and ecologically in the Bering Sea and Aleutian Islands (BSAI). However, little is known about its spawning dynamics. To address this knowledge gap, I developed a gross anatomical maturity key for Pacific cod to assess temporal and spatial patterns of...

An internship at NWAFC : The Bering Sea crab database

Creator:: McDowell, Michael K.
Abstract:: I served an internship with the National Marine Fisheries Service (NMFS), Northwest and Alaska Fisheries Center (NWAFC), Resource Assessment and Conservation Engineering (RACE) division in Seattle, Washington from June, 1983 to December, 1983. This experience proved to be very rewarding because of the techniques I learned, the job experience I...

Ecology of Greenland halibut (Reinhardtius hippoglossoides) during the early life stages in the Eastern Bering Sea and Aleutian Islands

Creator:: Sohn, Dongwha
Abstract:: Greenland halibut (Reinhardtius hippoglossoides) have decreased in the eastern Bering Sea and Aleutian Islands since the 1970s. The reasons behind the poor recruitment are unknown, and important knowledge gaps of the ecology of the early life stages have been identified. The objectives of thesis research were (1) to examine geographic...

Detection, classification and ecology of acoustic scattering layers

Creator:: Cade, David Edmund
Abstract:: Acoustic scattering layers of biological origin have been observed for nearly 70 years across the world’s oceans. The organisms that comprise these layers are known to be important features in most oceanic ecosystems, providing a vital trophic link between small phytoplankton grazers and larger species. There are many aspects of...
