From the Star-Tribune:
_Somebody has introduced walleye into Buffalo Bill Reservoir west of Cody, and the Game and Fish Department is offering a reward of up to $10,000 for information leading to the apprehension of the person or persons who “bucketed” the fish in, said Steve Yekel, Cody region fisheries supervisor. . . .
One of the major concerns about this illegal walleye introduction, Yekel said, is that the fish will add to the struggles of the Yellowstone cutthroat trout in the North and South Fork Shoshone Rivers. . . .
[The] Yellowstone cutthroat . . . is compromised by cross-breeding with rainbow trout, . . . is being out-competed at times by other species [and] . . . is already being hunted in the area by lake trout, or mackinaw, Yekel said, and adding another predator could be disastrous._
