Deadly VHS virus found in Lake Superior

TRAVERSE CITY, Mich. (AP) - Researchers say a fatal fish virus has been found in Lake Superior for the first time, meaning it has spread to all the Great Lakes.

Cornell University scientists say they recently detected viral homorrhagic septicemia, or VHS, while testing fish from seven locations in Lake Superior.

VHS has been identified in 28 freshwater fish species within the Great Lakes watershed since 2005. It has caused large fish kills in lakes Ontario, Erie and Huron. It also has turned up in Lake Michigan.

Officials in Michigan and Wisconsin said Wednesday there was no evidence of a widespread outbreak in Lake Superior. They said the Cornell findings would not lead to any immediate changes in regulations of fishing or boating.

Both states already limit movement of bait fish to prevent VHS from spreading.
