Fish Ecology Along Modified Shorelines
Waterfronts are busy places. Ancient civilizations often formed along the water where people benefited from aquatic resources and trade. People have continued to develop waterfronts, and these areas are now major components ... -
Fish resource use and habitat coupling in lake ecosystems
Mobile consumers frequently acquire and use resources from differing habitats. This habitat coupling can influence ecosystem function, stability, and structure. Mobile consumers such as freshwater lacustrine fish are known ... -
Fisheries stock assessments for commercial Alaskan species, accounting for age-size-structured population dynamics
This thesis develops a framework for conducting stock assessments that unifies age- and size-structured assessment models, creating what we term “age-size-structured models.” Several studies have explored the application ... -
Fishery Performance Indicators (FPIs) and Production Analysis: What Works Before and After the Ban of Cantrang Trawl Fishing in the Java Sea–Indonesia
The Fishery Performance Indicator (FPI) and production analysis are used to asses and evaluate the impacts of a partial ban on performance of the Cantrang -a modified Danish seine that targets demersal species and squid- ... -
Fishing for nutrition - improving the connection between fisheries, the food system and public health
Fish and shellfish are rich in micronutrients. As aquaculture production grows and the pathways to sustainably manage our capture fisheries become clear seafood is positioned to play a major role in the fight against ... -
Food web impacts of geoduck clam aquaculture practices in Puget Sound, Washington
(2014-02-24)Aquaculture operations are a frequent and prominent cause of anthropogenic disturbance to marine and estuarine communities. In Puget Sound, Washington, aquaculture of the Pacific geoduck clam (<italic>Panopea generosa</italic>) ... -
Food–web implications of reintroducing anadromous salmonids in reservoirs on the North Fork Lewis River, Washington
Reintroductions using active transport (trap–and–haul) of anadromous salmonids around impassable high–head dams are being proposed with increasing frequency in the Pacific Northwest. Such reintroductions have already begun ... -
Foraging Ecology and Population Dynamics of Northern Sea Otters (Enhydra lutris kenyoni) in Washington State
Many marine mammal populations are currently recovering from population depletion after overharvest. As marine mammals are often important predators in shaping marine ecosystems, there is a need to understand the impacts ... -
Genetic and phenotypic diversity in sockeye salmon, Oncorhynchus nerka
(2013-02-25)The work described here was motivated by a need for improved genetic tools for the management of sockeye salmon, specifically those populations inhabiting Bristol Bay, and a desire to better understand the process of ... -
Genetic differentiation of chum salmon in Alaska influenced by glacial history
(2013-04-17)One major goal of fisheries management is to ensure the sustainable harvest of wild populations so that productivity is stable over time. Information on population structure is necessary for effective fishery management ... -
Genetic interpretation of microsatellite polymorphism in Pacific salmon: case studies in population genetics and kinship analysis
(1999)I conducted five independent studies focusing on development and application of microsatellite DNA for intra-specific genetic analyses of Pacific salmon (Oncorhynchus spp.). I developed techniques for multiplex analysis ... -
Genomic and Fitness Consequences of Hybridization between Cutthroat and Rainbow Trout
Hybridization is an important and common evolutionary process that can contribute to diversification, adaptation, and speciation. When species hybridize, divergent genomes are combined through recombination and may result ... -
Genomic Consequences of Hybridization between Rainbow and Cutthroat Trout
Introgressive hybridization creates novel gene combinations that may generate important evolutionary novelty and thus contribute to biological complexity and diversification. On the other hand, hybridization with introduced ... -
Genomic signatures of natural selection and population structure in West Coast and Alaskan sablefish (Anoplopoma fimbria)
Previous population genetic studies have not been able to find clear population genetic structure across the range of the sablefish (Anoplopoma fimbria) in North America. They have focused on using a relatively small number ... -
Growth and maturity of Longnose Skates (Raja rhina) along the North American West Coast
Information on the growth and maturation of exploited fishes is important for assessing and managing fish populations. These life history processes commonly vary spatially and temporarily in marine fishes due to environmental ... -
Hatcheries, phenology, and families: Juvenile steelhead ecology in Forks Creek, Washington
(2014-04-30)Juvenile ecology can affect subsequent population dynamics. This work focuses on two aspects of juvenile steelhead (Oncorhynchus mykiss) ecology: 1) tradeoffs between naturally-spawned hatchery and wild fish, and 2) the ... -
Hierarchical models of fishing behavior by factory trawlers in midwater-trawl fishery for Pacific hake (Merluccius productus)
(1998)The fishing behavior of factory trawlers in the Pacific hake (Merluccius productus) fishery at different spatio-temporal scales was studied using several modeling techniques. In Chapter 1, a Markov decision process model ... -
History and extent of introgressive hybridization in Puget Sound rockfishes (Sebastes auriculatus, S. caurinus, and S. maliger)
(2013-02-25)Natural hybridization is common in closely related species especially where they invade novel habitat. The patterns of introgressive hybridization are often asymmetrical and are attributed to various influences from selection ...
