Improving Green Sturgeon Population and Migration Monitoring

Description / purpose

Green sturgeon is a listed species under the federal Endangered Species Act. This project supports the recovery and management of the southern distinct population segment of green sturgeon by improving population and migration monitoring. Improved monitoring is recommended in multiple initiatives to help protect this species, such as the Green Sturgeon Recovery Plan. There is some uncertainty on whether the most appropriate green sturgeon monitoring techniques are being used. This project compares the different estimation and monitoring techniques to identify the superior protocol. To compare the effectiveness of different techniques, scientists will monitor green sturgeon in the Sacramento River using sonar technology. Monitoring data will be used to estimate the population size and death rates due to by-catch. This project will also review and synthesize past acoustic telemetry data to determine if the data can be modeled to improve population size estimates.
