Jeff Jorgensen

Research Fish Biologist


Before joining the NWFSC in 2005, Jeff Jorgensen's previous work has included Midwest-ceded territory treaty fisheries issues, landlocked Laurentian Great Lakes sea lamprey alternative life history strategies, and associated host mortality, predator-prey and fish community dynamics. He earned a B.A. in economics from the University of Minnesota, a B.S. in biology from the University of Washington, and an M.S. from the University of Wisconsin Madison, Center for Limnology, in limnology and marine science.

Current Research

Currently, Jeff is focused on salmonid recovery-related projects, including linking landscape attributes to freshwater salmonid habitat requirements, which are used to parameterize population dynamics models to determine potential responses of fishes to restoration actions. His research interests include population responses to the four H's, climate, and other factors, as well as research on historical population and ESU structure. He is also currently working with external collaborators to develop simple classification models that use vertebrae morphology to identify salmonid vertebrae (Oncorhynchus spp.) to species.
