USGS Scientist have some interesting new findings on Southern Appalachian Brook Trout.

Fly anglers in the south love their brook trout. While many western anglers see these fish as an invasive species, here in the southeast they are our only native trout and our southern fish are genetically unique. It turns out they are more unique than we thought. Their habitat is so fractured that there are as many as ten-thousand separate populations.

There is some good news and some bad, but one notable finding is that native brook trout have suffered less hatchery introgression than expected. In this article USGS researcher Dave Kazyak’s sits down for a conversation with Keith Curley, of Trout Unlimited, to share some of his findings.
