YELLOWSTONE FACES NETTING OF LAKE TROUT

A panel of fisheries experts says there is no practical way to rid Yellowstone Lake of illegally planted lake trout that threaten Yellowstone's treasured native cutthroats.

Expensive - and perpetual - netting of the unwanted lake trout will be needed even to limit their impact on the cutthroat, a critical food source for other Yellowstone wildlife from grizzly bears to pelicans.A boat and crew would go onto the lake every day it is clear of ice and sweep the lake's depths with nets. The nets would catch lake trout but allow the smaller cutthroat to escape.
