This study demonstrated that acoustic telemetry, drone surveys, and eDNA are effective tools for tracking the movement, habitat use, and behavior of experimentally released adult Chinook Salmon in the Canadian portion of the Columbia River. The findings support continuing and expanding the program to better identify key holding and spawning areas, assess spawning habitat quality, and evaluate early life stage survival.
As a single-year study limited to one portion of the transboundary system, the results highlight the need for a comprehensive, multi-year collaborative effort. Expanding this work will improve understanding of post-release behavior and help guide future restoration and management efforts under the Bringing the Salmon Home Initiative.
