Last night, fisheries biologists from Yellowstone National Park and members of Wyoming Trout Unlimited gave a great presentation on the Parks ongoing efforts to save and restore native cutthroat trout populations. As some of you know, the park has been waging an aggressive campaign to save the Yellowstone lake cutthroat by killing invasive Lake Trout.
Lake Trout (mackinaw) were illegally introduced to Yellowstone lake somtime in the '80s and have dramatically reduced the native cutthroat trout in the lake over the years. Fortunately the Park is making progress fighting the invasion, killing more and more Lakers over the years. Unfortunately there's a lot of misinformation out there waged by a select few folks who like catching lake trout and have a surplus of time on their hands. It's clear that Lake trout are killing Yellowstone cutthroat and wreck havoc on the entire ecosystem; an ecosystem that depends on the Yellowstone Lake cutthroat to thrive. I for one am glad the Park and its supporters are working so hard to save and protect this amazing fishery.
Also, the Park is in the process of restoring native Grayling, Yellowstone and Westslope Cutthroat to a few select streams in the park. Check out the link below to learn more about the Parks management plan and learn facts about their battle.
