The effort to remove non-native lake trout from Yellowstone Lake seems to once again be paying dividends.

After years of a full-scale attempt to rid Yellowstone Lake of nonnative trout that feed on native cutthroats, Yellowstone National Park experts say they’re succeeding in reducing the lake-trout population.

Netting operations on Yellowstone Lake have yielded higher numbers of both invasive lake trout and cutthroat trout, leading officials to declare progress in the battle to save native species.

The efforts to clear Yellowstone Lake of unwanted lake trout is going high-tech, with 140 trout implanted with radio transmitters to track their movements and show researchers the best places to attack spawning areas.

The National Park Service is waging a losing battle against the invasive lake trout as it slowly takes over Yellowstone Lake to the detriment of other trout species, according to Trout Unlimited, who want to see more aggressive actions taken against the interloper.

The National Park Service has started work on a Native Fish Conservation Plan for Yellowstone National Park, as officials plot the outlines of a Park-wide attempt to eliminate non-native species from Lake Yellowstone and other streams and lakes.
