New Zealand Mud Snails Found in Russian River

I read over the report at http://lakeconews.com/content/view/5631/764/

and noticed the DFG prevention tips did not mention any type of chemical mixture, like 409 commercial disinfectant.� Rather, physically remove, freeze, and/or let dry.� DFG still has links on their site for the prevention and equipment damage studies...Any reason why they would omit this information in the article?� Just curious.

According to Ken Davis, who directed some of the 1st treatment studies, the most recent ones have not confirmed the efficacy of 409 as a disinfectant. The most effective treatments are freezing exposed gear overnight, or elevated temperature for a few hours; the former is definitely easier on your breathables. Copper sulfate is an effective poison but is toxic to the environment so not a good idea, even if you could get your hands on it.
