Electrofishing Survey Reveals Surprise Brown Trout

By Gretchen Schenk



The aquatics crew uses an electrofisher
to stun fish and more effectively find them.

Last August, Upper Snake Creek was chemically treated to remove the non-native brook trout to make way for the reintroduction of native Bonneville cutthroat trout. Immediately after the treatment, the stream was electroshocked to ensure that no brook trout remained. No fish were found. This May the stream was electroshocked again, and one brown trout was found near Shoshone campground. Since brown trout have never been found in Upper Snake Creek, and we find it unlikely they swam from lower Snake Creek through a three mile pipeline and then an additional two miles, we think it's most likely that the brown trout arrived in its location via a bucket.

We need your help to keep fish where they belong. Do not move fish from one watershed to another or between different parts of the watershed. Not only could it spread disease, but it's also illegal.

We will shock Upper Snake Creek in early August to check again for fish. If no fish are found, Upper Snake Creek will be ready for reintroduction of Bonneville cutthroat trout, which will be provided by the Nevada Division of Wildlife.


Gretchen Schenk, Ecologist, is focusing on Bonneville cutthroat trout and aquatics projects this summer with the help of the Aquatics Crew: Missy Brickl, Rob Colvin, Bryan Hamilton, Stephanie Leslie, Matt Proett, Nancy Williams, and Heather Vice.
