How to Stop the Spread of Whirling Disease
 
By now you have probably heard that Lee's Ferry tested positive for whirling disease. This is certainly not good news but it isn't the end of the world.

What is Whirling Disease?
"Myxobolus cerebralis is a metazoan parasite that penetrates the head and spinal cartilage of fingerling trout where it multiplies very rapidly, putting pressure on the organ of equilibrium. This causes the fish to swim erratically (whirl), and have difficulty feeding and avoiding predators. In severe infections, the disease can cause high rates of mortality in young-of-the-year fish. Those that survive until the cartilage hardens to bone can live a normal life span, but are marred by skeletal deformities. Fish can, however reproduce without passing on the parasite to their offspring." (courtesy of www.whirling-disease.org)

I received a call from Larry Riley, G&F Head of Fisheries, and he asked me to help get the word out about what we can do to keep it from infecting more fisheries in the state.

Since whirling disease can live in a pair of waders for up to 30 years, it is crucial that anglers take a proactive approach in order to stop the spread.

It is very easy to stop the transfer and only takes a few minutes of your time. To clean waders and boots, use a 10 to 1 water to bleach solution. Use a spray bottle to saturate your waders and boots and then let dry. (10 ounces water mixed with 1 ounce of bleach). I have used this solution many times and found that it is not harmful to my gear. Larry also said that 409 cleaner will kill the parasite but I have no personal experience with using it.

Please help spread the word to all your angler friends so that we can keep all of our fisheries healthy.

Is there a list out there with locals of WD in the states. I see they list states, but not sites within the states...?????

That's a good question and one that I don't have an answer to.

I do know that the San Juan River has it and a lot of us fish there.

If I come across that information, I will pass it on.

Thanks, i think reguardless we need to make sure gear is clean!

The Ferry
 
I want to add that this discovery is not a reason to stop going to the Ferry. As said above, the San Juan has had WD for years and has faired pretty well.

Lee's Ferry has certainly had more than it's share of problems, from trying to save an endangered fish downstream to radical flows. For the first time in a very long time, it is a good fishery again with people catching a lot of fish and some bigger fish.

This thread was intended to make everyone aware that we have a responsibility to our fisheries and to give information about the spread of WD.

Ok, that's all I've got to say. :)

I am off for a long weekend in the White Mountains.

This is good info - and should be a habit among fisherman traveling to and from different watersheds -

I recently read a fascinating article about how the Colorado DNR is researching whirling disease and trying to introduce a strain of rainbow trout from Germany that is immune to WD. I didn't know that Brown trout are unaffected from this disease until reading the article. They have successfully bred one line of fish that are resisting the parasite but want to conduct the test through a few generations before posting results.

I typically wet-wade, and I typically do it in my hiking boots, hiking pants, and gaitors. I'll look around for details on how to treat these. I don't want to spray bleach on my leather boots. Wet wading brings their life span down to about 2 years, but bleach would probably half that again. I'm also interested if the washing machine does the trick on my socks and pants. I never wash my gaitors, but I'll start doing that too.
