For decades the National Park Service has been locked in a battle against lake trout, an invasive fish with a voracious appetite that has overtaken Yellowstone Lake and upended its formerly thriving ecosystem. According to new research, an aircraft-mounted instrument could offer a faster way to locate and capture the non-native fish during the brief weeks each year when they come into shallow water to spawn.
The instrument, which uses the light-based imaging technology Light Detection and Ranging (LiDAR), could allow those who manage the lake to hunt for invasive fish across a wider area at a lower cost, making more efficient use of the approximately $2 million spent on lake trout control each year.
