A fatal fish virus has been detected in Lake Superior for the first time, meaning it has spread to all the Great Lakes, Cornell University researchers said Wednesday. Scientists said they recently detected the viral hemorrhagic septicemia, or VHS, while testing fish in the largest of the Great Lakes. VHS has been identified in 28 freshwater fish species within the Great Lakes watershed since 2005, including sport and commercial varieties such as walleye, muskellunge and whitefish. It causes bleeding, bloated abdomens and bulging eyes in fish before killing them. |

Fishery managers have made little progress in restoring lake trout, the Great Lakes' dominant predator until the species collapsed in the 1940s and 1950s.
Most of them agree that alewives, a non-native fish, are a big part of the problem. They invaded the lakes from the Atlantic Ocean after the Welland Canal opened in 1932. Alewives eat young lake trout and disrupt chemical processes important to their reproduction.

Scientists recently discovered wild young Atlantic salmon in New York’s Salmon River. This is the first time in more than a century that salmon produced naturally in the wild have been found in what was once New York’s premier salmon stream. Forty-one wild Atlantic salmon were collected in June and July. All of the salmon were under one year old and ranged in length from about 2 – 2.5 inches.
“This discovery suggests that, after many years of reproductive failure, restoration is starting to work for this species,” said Jim Johnson, Station Chief for the U.S. Geological Survey (USGS) Tunison Lab of Aquatic Science in Cortland, NY. “This finding should provide real excitement and impetus for biologists and sport groups interested in bringing this species back to the area,” said Johnson, whose lab made the discovery.
