Nonnative lake trout have been illegally introduced into Yellowstone Lake.  This has created a problem for the current native fish, the cutthroat. It could be difficult to relocate the lake trout while not disturbing the cutthroat. However, using gill nets to capture the lake trout may be the best solution to this dilemma.   They could then be returned to their original home.  This would cut cost while reducing the lake trout population. The pro’s to this solution would be more population of the cutthroat fish. There would be no need to eliminate all fish life.  Bears and other wildlife would stay in the area that is their home. Fishermen could continue fishing for the native cutthroat. This could also be more cost effective.  The con’s would still require a lot of money for equipment and labor.  There is no guarantee all lake trout could be removed.  There could still be problems for the cutthroat. Eliminating the lake trout entirely and reintroducing the cutthroat could cost between $32 and $181 million. By gill netting the fish, it seems to be the best solution.
