California Freshwater Fish Laboratory

Principal Investigator - Lisa C. Thompson

Our research and outreach focuses on fish issues in California. We look for solutions to fisheries issues that conserve and restore fish populations while also allowing human uses of natural resources such as agricultural lands, water, and hydropower.

We conduct applied fisheries research designed to resolve significant issues, knowledge, or data gaps related to California fish. A main goal of this research is to develop improved management practices, and to facilitate the adoption of these practices. Our research interests include: adaptive management of anadromous and inland fish populations; population dynamics modeling; impacts of dams and other water diversions on aquatic ecosystems; food webs in rivers, lakes and reservoirs; and terrestrial-aquatic linkages in watersheds. Recent projects include: 1) Effects of dams and flow regulation on fish; 2) Climate change, particularly as it relates to the recovery of threatened spring-run Chinook salmon; and 3) Temperature preference and tolerance of steelhead/rainbow trout and hardhead minnows.

Our outreach work provides scientific information about California’s anadromous and inland fish to the people of California. This information is communicated in person through presentations, workshops, training sessions, and individual consultations, and indirectly, through this web site, publications, computer software, audio-visual materials, and other reference materials.

Our research and outreach projects take place on private and public lands and waters, including rivers, lakes, and reservoirs. We often work in partnership with several other research laboratories, UC Cooperative Extension Advisors, private landowners, resource agency staff, non-governmental organizations, non-profits, and tribal groups.

This site provides information on our projects, publications, and presentations, as well as information for prospective students. Please feel free to contact us with questions or ideas.
