Science for adaptive management of juvenile spring-run Chinook salmon in the San Joaquin River
Description / purpose
Spring-run Chinook salmon rehabilitation efforts are intensifying on the San Joaquin River. Over the last three years, UC Davis has successfully tracked movement, behavior, reach-specific survival, and route selection for reintroduced juvenile spring-run Chinook salmon in this ecosystem. In 2019, information on salmon tracking was combined with state-of-art habitat (fast limnological automated measurements or “FLAMe”) and physiological (e.g. fish condition, survival and transcriptomic) approaches. Results from this work are ongoing but have yielded actionable information on key habitats and management strategies for promoting salmon life-cycles in the San Joaquin River and central Delta. Now UC Davis will further explore promising recent findings. First, the analysis of an additional year of juvenile salmon tracking will occur to glean more survival information across different water year conditions. This information would be married with expanded FLAMe surveys in space and time along with a second year of physiological assays using caged fish. UC Davis will also evaluate the ‘transport effect’ on salmon, in an attempt to explain consistently high losses of JSATS-tagged salmon through the restoration area. Numerous other synergies exist with new and ongoing telemetry work that will be benefitted by a continuation of this work. The goal is to provide actionable science, and open access data, with a high potential to facilitate adaptive management in the San Joaquin River and central Delta.
