Trout Unlimited and the University of Calgary want people who are out fishing, hiking or exploring along rivers in Alberta to sample rocks for Didymospehnia geminata, commonly known as Didymo and nicknamed rock snot for its mucous-like stickiness.
Its a slimy, green aquatic algae that grows along the stream bottom.
Were asking anglers to collect samples for us, said Lee Jackson, a professor in the department of biological sciences in the Faculty of Science at the U of C. We are using it as a means to sample locations that we havent sampled before.
