cutthroat trout

Cutthroat trout are the only trout native to the Snake River drainage and the biggest measured almost 15 inches.

A sexually mature lake trout starts laying eggs at age 5-6 and can live as long as 50 years.

Native cutthroat are the park's most ecologically important fish because it is a food source for grizzly bears, birds of prey and other wildlife.

Fishermen say cutthroat trout are rapidly replacing lake trout in Yellowstone Lake.
