Established as a scientific leader on fish and water issues in the state, CalTrout roots its projects in research to drive innovative, science-based solutions to the state’s resource issues.
In April 2021, CalTrout sponsored and presented at the 2021 Virtual Salmonid Restoration Federation (SRF) Conference. The annual SRF Conference offers an unparalleled opportunity for professionals, academics, and scientists to present their research to a large audience of fisheries restoration enthusiasts.
The SOS II: Fish in Hot Water Report, published in 2017 by CalTrout and UC Davis Center for Watershed Science, was a staple reference during the conference. Researchers continue to look to this publication as the pinnacle, in-depth report detailing the status of California’s 32 native salmon, steelhead, and trout. This report also guides our five key initiatives informing our on-the-ground restoration including Protect The Best, Reconnect Habitat, Integrate Wild Fish and Working Landscapes, Steward Source Water Areas, and Restore Estuaries.
Several CalTrout researchers presented at the 2021 SRF conference speaking on topics from dam removal to fish food webs. Check out the recordings and description of the talks below.
Facilitated by Rob Lusardi, CalTrout/UC Davis Wild and Coldwater Fish Researcher
Efforts to conserve at-risk populations of anadromous Pacific salmon (Oncorhynchus spp.) often focus on the restoration of physical habitat features (e.g., water temperature, pool frequency and depth, large wood abundance, etc.) associated with enhanced juvenile production in freshwater. However, there is growing recognition that restoration and protection of suitable habitat must consider interactions between physical habitat features, ecosystem productivity, and fish performance. Recently, numerous scientists have called for a broader understanding of how prey availability and food webs affect the growth, persistence, and survivorship of juvenile salmonids. We seek abstracts that examine the effects of food webs and aquatic habitat productivity on the growth of juvenile salmonids particularly in productive ecosystems or where food webs strongly interact with physical habitat attributes to influence growth.

Making Sense of Making Salmon: Recipes for Routing Landscape Carbon into Fisheries Biomass

Facilitated by Darren Mierau, CalTrout North Coast Regional Director
Throughout the United States, aging dams and fish barriers of all sizes represent an unprecedented opportunity for salmon restorationists. By removing barriers to migration, we can restore fish access to spawning and rearing habitat, as well as increase streamflows and reduce harmful temperatures and algal blooms. This session will explore the many facets and stages of successful and ongoing dam and fish barrier removal projects throughout California, from permitting and project initiation to decommissioning and river restoration.

Peter Moyle is the Distinguished Professor Emeritus in the Department of Wildlife, Fish and Conservation Biology and Associate Director of the Center for Watershed Sciences, at UC Davis. He is author or co-author of more than 240 publications, including the definitive Inland Fishes of California (2002). He is co-author of the 2017 book, Floodplains: Processes and Management for Ecosystem Services. His research interests include conservation of aquatic species, habitats, and ecosystems, including salmon; ecology of fishes of the San Francisco Estuary; ecology of California stream fishes; impact of introduced aquatic organisms; and use of floodplains by fish.
Robert Lusardi is the California Trout/UC Davis Wild and Coldwater Fish Researcher focused on establishing the basis for long-term science specific to California Trout’s wild and coldwater fish initiatives. His work bridges the widening gap between academic science and applied conservation policy, ensuring that rapidly developing science informs conservation projects throughout California. Dr. Lusardi resides at the UC Davis Center for Watershed Sciences and works closely with Dr. Peter Moyle on numerous projects to help inform California Trout conservation policy. His recent research interests include Coho salmon on the Shasta River, the ecology of volcanic spring-fed rivers, inland trout conservation and management, and policy implications of trap and haul programs for anadromous fishes in California.
Patrick Samuel is the Conservation Program Coordinator for California Trout, a position he has held for almost two years, where he coordinates special research projects for California Trout, including the State of the Salmonids report. Prior to joining CalTrout, he worked with the Fisheries Leadership & Sustainability Forum, a non-profit that supports the eight federal regional fishery management councils around the country. Patrick got his start in fisheries as an undergraduate intern with NOAA Fisheries Protected Resources Division in Sacramento, and in his first field job as a crew member of the California Department of Fish & Wildlife’s Wild and Heritage Trout Program.
