Fishery officials are still considering options for eliminating Lake Davis’s population of razor-toothed northern pike, a fierce game fish that could threaten salmon and trout populations if it slips into the adjoining river system. Introducing pike-specific diseases and draining the lake have been ruled out. Four years ago, poison was added to the lake in order to eliminate the pike. This outraged local residents, because the water remained tainted for months and the region’s tourism economy suffered.

Summary
Fishery officials are still considering options to eliminate a breed of pike from Lake Davis. Introducing disease and draining the lake have been ruled-out as options. Four years ago, poison was added to the lake and caused an outrage among residents.
