Lake Sturgeon Health Assessment

This project will determine concentrations of PCBs in sturgeon eggs that will be protective of fish populations. We will evaluate reproductive effects of PCBs found in Areas of Concern and throughout the basin. Hatchery sturgeon with varying levels of PCBs in their tissues or sturgeon eggs dosed with PCBs under controlled conditions will be used to determine thresholds in tissue that represent unacceptable risk and injury. We expect the results to influence cleanup and restoration decisions and natural resource damage assessments to improve habitat quality and fisheries.
