Burbot are invading the Green River and Flaming Gorge fisheries in Wyoming and Utah.
A species of fish called the burbot (pron: burr-bit) was illegally introduced into the Green River in Wyoming. They have since migrated to the Gorge. Burbot feed on crayfish, directly competing with small mouth bass and lake trout for that food source. In some cases, burbot will feed on the young of other species as well.
