    Quantitative Indicators and Life History Implications of Environmental Stress on Sturgeon

    Lead University of California - Davis [UC Davis]
    Description The purpose of this project is to analyze the effects of the pollutants on the overall fitness of different life stages of the green and white sturgeon. This research will significantly enhance our understanding of stressors on sturgeon and allow further development of life history models.

    Synchrony of Native Fish Movements: Synthesis Science Towards Adaptive Water Management in the Central Valley (FishSync)

    Lead University of California - Davis [UC Davis]
    Description Salmon and other native California fishes are in decline and increasingly targeted for enhanced conservation. Acoustic telemetry technologies have emerged, allowing researchers to track fish routes through the Central Valley. Yet while the use of acoustic telemetry has widened, little synthesis has occurred on the large, growing, and expensive datasets that already exist. The main goal of the project is to conduct a synthesis study of existing and high priority telemetry datasets for native and non-native fishes in the Central Valley. Using synchrony of movement rates, through space and time, we will develop a novel behavior-based statistical framework to gain understanding into the environmental conditions that promote movement/passage of diverse native fishes in the Central Valley. The project includes a Technical Advisory Group, composed of members of multiple conservation teams. The group will inform each step of study, strengthen syntheses, and enable rapid communication of results to decision makers. In total, the project will analyze 10 to 15 high-quality telemetry datasets encompassing a range of native fishes and life stages. This synthesis will yield major insights into water management practices that could help improve survival of native fish.

    Open-Source Resources for the Sacramento-San Joaquin Delta Telemetry Research Community

    Lead Cramer Fish Sciences
    Description There is a great deal of telemetry data amassed from studies in the Sacramento-San Joaquin Delta. It continues to grow every year with special studies and monitoring efforts. Multiple research priorities surrounding fish ecology in the Delta could be addressed, at least in part, by synthesizing the myriad telemetry data sets that exist; this work would benefit greatly from the centralization and standardization of data workflows surrounding telemetry research. With the guidance of a PIT Advisory Team, we plan to establish a collection of open-source, technology-agnostic, accessible resources to support a reproducible and transparent telemetry data workflow for researchers in the region. The workflow and resources do not invent new procedures, rather improve and standardize those already used by the telemetry research community. This will bring us in closer alignment with centralized, coordinated data workflows that have been successfully implemented in other regions and data communities. The final open-source set of resources will include a design and roadmap for implementing a central telemetry database and workflow, an R package for the preparation, QA/QC, and basic analysis of telemetry data, and a regional workshop offering training programs in the proposed telemetry data workflow.
