Didymo

Not sure if this is the proper place on the forum. However, it seems to me that part of conservation is not cross infecting the streams. Or looked at another way. Sometimes it's not us contaminating the streams. The streams contaminate us and we carry the contamination to another stream.

Is Didymo a problem where you live? How do you go about cleaning your equipment before going to the next stream? Didymo may not exist where you live but perhaps does in another state you intend to visit and fish. It may pay to be aware of it and ready to deal with it before you go.

I had never heard of Didymo until I saw this web site prior to taking a short vacation. I was looking on line to locate directions to local in-state trout streams near to where we would be staying. I had good success with my new Tenkara gear on the pan fish in streams close to home. I was ready to find out how I’d do with trout.

and later on this web site:

Here is a copy of one of the two posters seen streamside here on posted streams. It also contains a distribution map of states where Didymo has been found. While it is not it all states Didymo is nationwide.

I saw another map on an EPA web site showing it is a world wide problem. Worse in some countries than here.

There is short, 2”, video on this web site from May 2009, talking about what it is and showing one way to disinfect waders, boots, etc, with a solution in a spray bottle to treat your clothing. It aired on a local tv station.

While on my vacation I cleaned my Tenkara gear as best I could and just wore different clothing and shoes before going to a stream not posted. The collapsible nature of Tenkara rods may make them difficult to clean well. I have noticed that even if I clean the outside and dry the rod with it extended. Remove the end cap and you find its still rather wet inside. I just dropped my line spool into some water with the recommended solution presented on the web links above, rinsed it off and used it again.

I think I fished on 3 rivers that were posted and 2 that were not. On the rivers I fished that were posted I never saw the heavy 'river snot' shown in the video. Perhaps it was not the time of year to experience it in full force.

Other than not transporting fish yourself from one stream to another - are there other living organisms you are aware of that we should know about that can harm streams from getting on our own gear?

What are your experiences, practices, recommendations?

I fish one creek predominantly, but I always wash and dry my waders after each trip. I also dry everything - line, leader, rod - before storage. The waders I use are more designed for hunting, with big, open cleats underneath and less small surfaces for clinging "things".


If I do fish another body of water, I will not use a fly that might have been used on home water. I will typically replace leader, tippet and fly (or flies, when I lose them) for that trip and then "retire" everything to avoid any cross contamination. I try not to use waders away from home, but if I do, again they get thoroughly cleaned before going back into the water.

It may not be a perfect solution, but it is proactive and keeps me thinking about the waters I stalk.
