Background
Dan Bottom has served as a research fisheries biologist for 25 years, including 22 years with the Oregon Department of Fish and Wildlife. He has been a project leader for a wide range of salmon and ecosystem studies, including research on salmonid habitat requirements in stream and estuarine environments, fishery management and fish culture in the Northwest, and an assessment of wild salmon stocks across the entire North Pacific. In 1999, Dan joined the staff of the NWFSC to develop a new estuarine research program. He has a B.A. in botany from Duke University and an M.S. in marine studies from the College of Marine Studies, University of Delaware.
Current Research
Dan is now overseeing studies of juvenile salmon in the Columbia and Salmon river estuaries. In the Columbia River estuary project, Dan's team is participating in an interdisciplinary research program that includes broad-scale surveys of salmonid life history and habitat use throughout the lower estuary, studies of salmon-habitat associations and prey resources in emergent and forested wetlands. The team is also monitoring and modeling the physical factors affecting salmon habitat opportunity and creating a historical reconstruction of shallow-water habitat change throughout the estuary from the mouth of the Columbia River to Bonneville Dam.
In the Salmon River estuary project, the team is evaluating effects of wetland succession on physical habitat conditions, habitat use by salmon, availability of prey resources, and salmon bioenergetics.
