Yellowstone National park will be using new methods to remove the non-native lake trout from Yellowstone Lake, next summer
For the second year in a row, the park has been catching the lake trout, in order to help sustain the native cut-throat trout species in the ecosystem. Last summer alone, the park removed over 300,000 lake trout. Next summer, the park plans to use new techniques including killing the eggs of the lake trout.
"We're going to look at things like electroshock treatments to be able to kill those eggs. We also have a suction device that we're looking at to get rid of those eggs out of the rocks. So we have a lot of tools in the tool kit that we're trying to implement next year," says YNP spokesperson, Dan Hottle.
The park's effort to remove the lake trout will resume next may and continue through October.
