William R. Brignon

Bill is a Fish Biologist with the Analytical Services Group.  His primary area of focus is developing structured decision models to weigh the outcome of alternative management actions.  These decision models are the foundation of the USFWS’s Strategic Habitat Conservation initiative and are a necessity when conducting formal adaptive management.  Bill has also designed monitoring and research programs to evaluate ecological interactions between hatchery and wild fish, and how captive environments influence post-release behavior, development, and survival of fishes.  Bill is the co-lead on an 8 year study investigating the effects of Passive Integrated Transponder (PIT) tags on the survival of hatchery spring Chinook salmon.  Look for “The PIT Tag Effect Study” to be completed and written up in early 2018.
