Peter B. Moyle (born 1942 in Minnesota) is Distinguished Professor Emeritus in the Department of Wildlife, Fish and Conservation Biology and associate director of the Center for Watershed Sciences at the University of California, Davis.

This includes research over 40 years of monthly fish and macroinvertebrate sampling at multiple locations in Suisun Marsh.

Other early projects involved the identification and spatial delineation of different habitat types important to the state's freshwater species that could be used in management planning and application.

From the early days of Moyle's career at UC Davis, his reputation of “defending the underfish” (displayed on the Peanuts cartoon outside his office door) has profoundly pervaded the fisheries profession.

One of Peter's most profound influence on fish biology and fisheries science has been through his extensive cadre of students and other colleagues.
