Viral Hemorrhagic Septicemia, often called VHS, is a invasive fish virus affecting over two dozen species of fish in the US. Well known fish such as walleye, freshwater drum, and yellow perch as well as redhorse and gobies have died. Also affected are bluegill, smallmouth bass, black crappie and northern pike but they have died in smaller numbers and some have even overcome the disease.
VHS was found in European freshwater trout back in the the late 30's. It finally appeared in the US on the West Coast in marine trout and salmon in the 80's and was then noticed further north in New Brunswick, Canada earlier this decade.
Although VHS Is definitely an invasive species, scientists are unsure how it arrived. Some think the virus arrived via migrating fish and others think it may have arrived in the ballast water of large ships. Luckily, VHS is not a threat to people who want to eat their catch so, we are fortunate in that regard.

Symptoms include:
* Hemorrhaging (bleeding)
* Bulging eyes
* Unusual behavior
* Anemia
* Bloated abdomens
* Rapid onset of death
Unfortunately, these symptoms may indicate other diseases so, the existence of VHS can only be confirmed through lab tests.* Hemorrhaging (bleeding)

One of the easiest ways to prevent the spread of VHS, or any invasive species for that matter, is to exercise a little common sense and self control.
Providing it's legal, taking minnows from your favorite spot and trying them elsewhere is very tempting. Unfortunately, that's a sure fire way to spread invasive species. Also make sure any portions of your boat including the prop, that come in contact with water are clean.
Those two suggestion we can all do will go along way in keeping fish around for generations to come!

Remember to take the hooks outta yer pocket before ya sit down!
