YELLOWSTONE NATIONAL PARK, Wyo. -- An effort to cull invasive species from Yellowstone Lake has removed more than 300,000 lake trout from the lake this year.
The number of lake trout caught is the most in one year since fisheries managers first discovered the fish in 1994 in Yellowstone National Park's largest lake. The presence of lake trout has decimated populations of cutthroat trout, which are native to Yellowstone Lake.
The culling operation is finally reaching kill levels necessary to effectively suppress the ecologically damaging lake trout population, estimated at about 500,000 adult fish.
Yellowstone spokesman Dan Hottle tells the Jackson Hole News & Guide that officials are satisfied with the intensity of the lake trout kill and plan to hold netting at current levels into the near future.
