SMEA research scientist Aden Yincheong Ip and Professor Ryan Kelly have published a groundbreaking study in Scientific Reports exploring how airborne environmental DNA (eDNA) can be used to monitor salmon populations. Their study demonstrates that DNA from Coho salmon can be detected in the air, even 10–12 feet from waterways, opening new possibilities for non-invasive aquatic species monitoring.

Last fall, the team placed air filters at multiple locations along Issaquah Creek near the Issaquah Salmon Hatchery. To their surprise, the filters captured Coho salmon DNA, showing that airborne sampling could complement traditional water-based eDNA monitoring.

This innovative approach highlights the potential for using airborne eDNA to track aquatic species, offering a promising tool for conservation and fisheries management.
