A comparison of early marine residence in hatchery and natural Chinook salmon (Oncorhynchus tshawytscha)

Creator:: Claiborne, Andrew M.
Abstract:: The mechanisms of mortality during critical life stages of fish are not well-understood and, for many species, it is not clear if the mechanisms are similar for naturally and artificially propagated individuals. For Chinook salmon (Oncorhynchus tshawytscha), natural fish potentially face negative interactions, such as competition, and survival disadvantages, such...

Sandy beach surf zones : what is their role in the early life history of Chinook salmon (Oncorhynchus tshawytscha)?

Creator:: Marin Jarrin, Jose R.
Abstract:: Early life stages of many marine and diadromous fish species use sandy beach surf zones, which occur along >50% of the world's marine coastlines. This extensive habitat can provide juvenile fishes with an abundant supply of potential prey and the ability to hide from predators in its shallow turbid waters....

Trophically transmitted parasites as ecosystem indicators : relationships among parasite community structure, juvenile salmon diet composition, and ocean conditions

Creator:: Losee, James P.
Abstract:: Recent research conducted throughout the Northern California Current (NCC) on the ecology of Pacific salmon (Oncorhynchus spp.) indicates that variable ocean conditions affect the community composition of zooplankton in the nearshore environment which, in turn, can affect the quality of prey for fish, sea birds and mammals. Interannual variability in...

Year-class regulation of mid-upper Columbia River spring Chinook salmon Oncorhynchus tshawytscha : the role of juvenile size, growth, and migratory behavior

Creator:: Tomaro, Londi M.
Abstract:: Early ocean residence is assumed to be a critical period for juvenile Pacific salmon Oncorhynchus spp. However, the specific mechanisms influencing growth and survival in the ocean have not been identified for most populations. Therefore, three hypotheses regarding the relationship between early marine residence and subsequent survival of mid-upper Columbia...

Feeding Ecology and Growth of Juvenile Chinook Salmon (Oncorhynchus tshawytscha) During Early Marine Residence

Creator:: Litz, Marisa Norma Chantal
Abstract:: The early marine phase following freshwater emigration has been identified as a critical period in salmonid (Oncorhynchus spp.) life history, characterized by high but variable mortality. Consistent with the “growth-mortality” and “bigger-is-better” hypotheses, at least some of the mortality during the critical period appears to be size-dependent – with smaller...

Evaluation of Pacific Lamprey Entosphenus Tridentatus Anatomical Structures as Records of Age and Isotope Histories

Creator:: Pelekai, Keala N.
Abstract:: The anadromous Pacific Lamprey (Entosphenus tridentatus) is a biologically and culturally important species native to the North Pacific Ocean and its adjacent freshwater tributaries. Pacific Lamprey have experienced declines in abundance and distribution throughout their native range, highlighting a need for further research on the species to better inform conservation...

Feeding Ecology and Food Web Linkages of Yearling Chinook Salmon (Oncorhynchus tshawytscha) Migrating Through the Lower Columbia River and Estuary

Creator:: Munguia, Angelica
Abstract:: The Columbia River Basin historically supported abundant populations of Pacific salmon (Oncorhynchus spp.) but, largely due to anthropogenic influence, many populations are now listed as threatened or endangered under the U.S. Endangered Species Act. Habitat restoration efforts have been a critical component of salmon recovery plans. However, although the importance...

Pre- and Post-settlement Processes of Northern Rock Sole (Lepidopsetta polyxystra) in Relation to Interannual Variability in Temperature and Productivity in the Gulf of Alaska

Creator:: Fedewa, Erin J.
Abstract:: Understanding the effects of climate variability on growth dynamics and timing of early life history events in marine fishes can provide insights into survival, recruitment and productivity. Field collections (2005, 2007, 2009-2011) were combined with otolith microstructural analysis to examine interannual variation in larval and juvenile growth rates, size at...

Natal source contributions of Pacific cod (Gadus macrocephalus) recruits in the southeastern Bering Sea

Creator:: DiMaria, Ruth A.
Abstract:: Effective and sustainable fisheries management not only depends on identifying and defining stocks (fundamental unit of management), but also on having knowledge of factors influencing the abundance, distribution and connectivity of stocks. Population structure of Pacific cod (Gadus macrocephalus) in the southeastern Bering Sea (EBS) remains unresolved although genetic data...

Effects of Elevated CO₂ on Speckled Sanddab (Citharichthys stigmaeus) Behavior

Creator:: Andrade, Jessica F.
Abstract:: The direct and indirect effects of ocean acidification (OA) are a growing concern, particularly in areas already experiencing elevated levels of oceanic CO₂. Studies with marine fishes suggest that elevated CO₂ levels may affect behavior by interfering with an important brain neurotransmitter. Studies examining the effects of OA fish behavior...
