Hi Folks.

I help run a statewide volunteer stream monitoring program, Maryland Stream Waders (see, the volunteer component of the Maryland Biological Stream Survey (MBSS). Stream Waders volunteers sample aquatic invertebrates in wadeable, freshwater streams throughout Maryland. Beginning last year, we began decontaminating (with bleach) all MBSS equipment that contacts stream water to guard against the spread of didymo and whirling disease. Has anyone taken such precautions with volunteer stream monitors? We want to administer a protocol this year that will work with the 150 or so volunteers we expect to sample this spring.

Any advice would be greatly helpful.

We asked volunteers to follow disinfection protocols to protect against viral hemorrhagic septicemia (VHS) and other invasives. There are details in our summer newsletter and links in there to protocols (which are the same our Dept. of Natural Resources staff are asked to follow.

Here’s a link:

Only those people monitoring multiple locations were asked to follow the actual disinfection protocols since drying equipment is acceptable as well.

Let me know if I can provide other details.

As it relates to didymo….Our network just sent out an alert to the stream monitors within NJ. The alert was to notify them on what the stuff looks like (rock snot) and what to do to prevent spreading it….We may have to be more proactive with it.

According to Fish and Wildlife, NJ does not have a problem with it yet, but it’s coming.

Is anyone keeping track of this stuff in the NE?
