Assist Oregon Department of Fish and Wildlife (ODFW) in determining the extent to which genetic introgression exists between Snake River hatchery steelhead straying into the John Day Basin and the...
-
This project examines the factors influencing fish populations including habitat, harvest, hatcheries, hydropower system operations, and climate change. It seeks to estimate impacts of these...
-
This population historically migrated as subyearling smolts, but in recent years, the yearling life history has become more common. Environmental conditions associated with dams and reservoirs...
-
Drs. Marla Holt, Brad Hanson, and Candice Emmons of the NWFSC, along with collaborators from Cascadia Research Collective and UC Davis, are currently conducting a study using digital acoustic...
-
The Elwha Dams have been removed, with fish restoration to occur in areas previously inaccessible to salmonids. Fish recovery anticipates that genetic changes will occur to current populations,...
-
SRKW have several data gaps regarding their ecology. Diet of killer whales is being determined by analyses of predation events and feces and from stomach content of harbor porpoises. The potential...
-
Drs. Marla Holt, Brad Hanson, and Candice Emmons of the NWFSC, along with efforts from the NWFSC dive team (coordinated by Nick Tolimieri), are currently conducting passive acoustic monitoring of...
-
Orcinus spp. occur in the Pacific Ocean throughout the West Coast of North America. Data concerning their precise locations and abundance are critical to understanding their population trends and...
-
The Southern Resident killer whale (SRKW) population is threatened by a number of identified risk factors including prey availability, contaminants, vessel noise and disturbance, and small...
-
We are applying a variety of genetic tools to assess the response of our ocean resources to ocean acidification, including gene expression techniques, identification of candidate genes, and...
-
This work uses white muscle tissues collected from sixgill and sevengill sharks to characterize the diet of each species. Tissues from prey species have also been prepared in order to initialize...
-
Rainbow trout and steelhead consist of the same species and often inhabit the similar habitat types within the same watershed. Although their life histories differ from one another, there is...
-
The southern residents face several well-documented external threats. However, the population might also be subject to internal factors that limit population growth, including a reduction in...
-
Data for this project will reside in the West Coast Groundfish Bottom Trawl Survey Data Base. This proposal relates to a continuation and augmentation of our efforts in creating a DNA sequence...
-
We are using elliptic Fourier analysis to determine the patterns of variation in morphology of dorsal fin shape, saddle patch shape, and eye patch shape of resident, transient, and offshore killer...
-
This research was initiated by the Puget Sound Steelhead Technical Recovery Team to develop viability criteria for threatened Puget Sound steelhead and to support recovery planning of this...
-
This project is developing food web models for ecosystem-based management applications in Puget Sound. It is primarily being done by NMFS FTEs and contractors, in collaboration with scientists...
-
We are using genetic pedigree information to estimate the reproductive success of hatchery and wild fall-run Chinook salmon spawning in the Cedar River, Washington. Genotypes and associated...
-
The Salish Sea comprises most of the Puget Sound water area. Marine species are generally assemblages of discrete populations occupying various ecological niches. Genetic changes to populations...
-
This project is developing models to examine the ecological roles of bald eagles in the Puget Sound region. It is primarily being done by NMFS FTEs, in collaboration with scientists from the State...
