Trophic coupling and habitat connectivity among coral reef, mangrove, and seagrass fishes and benthic invertebrate communities of the Virgin Islands National Park (VIIS) and Coral Reef National Monument (VICR)

The connection between fish habitat utilization, prey use, and fish movement patterns is not known in relation to available invertebrate prey resources in off-reef sites. Developing a better understanding of the habitat use, diet, and resource needs of benthic communities and their interactions with mobile fish and invertebrates is an important More...

Field Study of Environmental Variables Influencing Abundance and Distribution of Desert Pupfish in the Salton Sea Basin

This study will compare relative abundance, population structure, and spawning success of desert pupfish from natural (reference) and manmade or disturbed habitats in the Salton Sea basin. In addition, this study will determine the importance of fish predation as a source of mortality in desert pupfish populations. Finally, this study will attempt More...

Estimating Survival Estimates for Migrant Juvenile Salmonids Passing Through the Dalles Dam Using Radio-telemetry

As anadromous juvenile salmonids migrate from freshwater rearing habitats to the ocean, they are vulnerable to a host of factors that affect their survival. Direct effects associated with dam passage (e.g., instantaneous mortality, injury, loss of equilibrium, etc.) and indirect effects (e.g., predation, disease, and physiological stress) More...

Evaluating Survival Estimates for Migrant Juvenile Salmonids Passing Through the John Day Dam Using Radio-telemetry

As anadromous juvenile salmonids migrate from freshwater rearing habitats to the ocean, they are vulnerable to a host of factors that affect their survival. Direct effects associated with dam passage (e.g., instantaneous mortality, injury, loss of equilibrium, etc.) and indirect effects (e.g., predation, disease, and physiological stress) More...

Transmission of Renibacterium Salmoninarum in Pacific Salmonids

Bacterial kidney disease (BKD) is caused by Renibacterium salmoninarum and is considered to be the most difficult salmonid bacterial disease to control, in part because of its dual modes of transmission. This bacterium, unlike most other fish pathogens, is transmitted vertically from parent fish to progeny in association with the eggs, as well as More...

Genetics of Alaskan Fishes

Genetics of Alaska Fishes Projects studies include comparing molecular genetics for rainbow trout throughout their range in Alaska and use microsatellite analyses to look at hatchery and wild populations of steelhead in the Snake River (Phylogeographic analysis of rainbow trout in Alaska). Research also looks at genetic population structure of More...
