Jun 22, 2007 — Alarming fish kills in the St. Lawrence River and Lake Ontario are blamed on a new virus that's spreading quickly. Viral hemorrhagic septicemia has already been found in Lake Erie, the Niagara River and--this week state environmental officials confirmed--the virus killed fish in Conesus and Skaneateles in the Finger Lakes. It's also spread to Canada, Michigan and Wisconsin. As its name suggests, the virus causes uncontrolled internal bleeding. In some species, it's easy to tell if you've caught an infected fish. They start to turn dark, almost black, as they're dying, which is likely due to hemorrhaging beneath the skin that makes their color darker. Steve LaPan is the Lake Ontario Unit Leader with the Department of Environmental Conservation. He says the St. Lawrence and Great Lakes ecosystems are already starting to suffer because of the virus.
