Yellowstone cutthroat trout

USGS researchers at the Montana Cooperative Fishery Research Unit, through research efforts and a strong partnership with Yellowstone National Park the Yellowstone cutthroat trout population has rebounded such that anglers are fishing the lake again, outfitters are booking back-country trips, and grizzly bears are visiting Yellowstone cutthroat trout spawning tributaries. Yellowstone National Park generates \$834 million in economic benefits and supports about 9,000 jobs for the local economy. A key part of this economic engine are the animals that the public come to see and enjoy. Once such species is the Yellowstone cutthroat trout, which people enjoy fishing for and is a food source for other animals, such as grizzly bears and eagles. Unfortunately, invasive lake trout entered Yellowstone Lake and collapsed the Yellowstone cutthroat trout population such that grizzly bears and anglers no longer caught the fish.
