Beyond Physical Habitat: the Importance of Prey Availability and Productivity in Recovering Imperiled Salmonid Populations

22 April 2022
9:00am - 5:00pm

Session Coordinator: Robert Lusardi, PhD, UC Davis Center for Watershed Sciences and California Trout Coldwater Fish Scientist

This session examines the importance of prey to foraging salmonids. Specifically, we are interested in understanding how prey availability may influence the growth and fitness of salmonids and identifying productive ecosystems or habitats that may assist in the recovery of imperiled populations. We are also interested in reconciled ecosystems or highly managed ecosystems that have the ability to improve productivity or prey availability at broader spatial scales and in an overall effort to improve habitat heterogeneity across the landscape.
