Peter Galbreath (503) 731-1250
At CRITFC since:

Quantitative Fishery Scientist

Fishery Science Department, Portland Main Office


My primary role with CRITFC is to provide guidance on policies concerning use of hatcheries and artificial production for the rebuilding of anadromous salmon and steelhead populations. I am currently coordinating several projects to assess relative reproductive success of natural-origin and hatchery origin fish, based on molecular genetics analyses conducted at the CRITFC molecular genetics laboratory at the Hagerman Fish Culture Experiment Center, Hagerman ID. These studies are focused on populations which were reintroduced with hatchery stocks (the original populations having been extirpated), with the objective of quantifying the relative amount and rate of increase in productivity of the new population as it readapts to the natural environment. Additionally, I am involved in studies which use a DIDSON™ sonar to estimate escapement of salmon in open river systems. Preferred activities outside of work include watching my son play soccer, refereeing youth soccer, cruising top-down in my 1974 MGB, brewing beer, and enjoying my wife’s homemade French cooking.
