Why is she blogging about zebra mussels? Zebra mussels are an invasive species. They were first detected in the Great Lakes in 1988, in Lake St. Clair, located between Detroit, Michigan and Windsor, Ontario. It is believed they were accidentally introduced into the lakes in the ballast water of ocean-going ships traversing the St. Lawrence Seaway.
Now to the point. Viral Hemorrhagic Septicemia (VHS) was first identified in the Great Lakes. VHS is a virus that has caused significant die-offs of different species of fish. I have heard it said that the spread of VHS might mimic that of the zebra mussel. I found this web site that follows the spread of the zebra mussel through the years. Take a look. Interesting.
