Utility of Parentage Based Tagging for Research, Monitoring, and Evaluation of Hatchery Programs within the Columbia River Basin
Abstract
Salmon and steelhead hatchery programs in the Columbia River Basin play a critical role in supporting healthy population abundances and mitigating the effects of hydrosystems. Parentage-based Tagging (PBT) is a modern genetic tool that has several advantages over conventional tagging methods (e.g., coded wire tags, physical marks, and Passive Integrated Transponders). The objective of this research was to test whether the following stock metrics for SY2023 Chinook salmon and steelhead collections had matching observed vs. expected values: Percent (%) PBT assignment rate; Age/Stock composition; and Bonneville Dam adult abundance compared to hatchery juvenile releases.
