CHICAGO (AP) -- A virus that has killed tens of thousands of fish in the eastern Great Lakes appears headed for Lake Michigan.
That's where wildlife experts fear viral hemorrhagic septicemia, or VHS, could threaten the sport-fishing industry.
The viral condition causes anemia and hemorrhaging in infected fish.
It was detected earlier this year in fish in an area of northern Lake Huron, about 20 miles from Lake Michigan.
It's been blamed for fish dieoffs last spring in Lakes Erie and Ontario as well as other waterways.
The Wisconsin Department of Natural Resources last week banned the use of imported bait unless it passes testing requirements, and outlawed the movement of live fish from the Great Lakes and the Mississippi River.
