FILE - This Aug. 31, 2011 file photo released by the U.S. Fish and Wildlife Service shows a dead fish on the ground after high floodwaters from Tropical Storm Irene flooded rearing tanks at the White River National Fish Hatchery in Bethel, Vt. Fish and Wildlife spokeswoman Terri Edwards said Wednesday, Dec. 21, 2011 that 434,000, 4-inch lake trout at the hatchery are being destroyed because of fears that stocking them in the Great Lakes could spread the invasive algae known as "rock snot."
