Fisheries biologist Chris Clancy of the Montana Fish, Wildlife and Parks will present updated information on the Bitterroot River at the Thursday, January 18, meeting of Bitterroot Trout Unlimited.

Clancy, who has been studying the river for many years will talk about the non-native fish removal on Overwhich Creek last year, the new recreation rules on the West Fork and the Upper Bitterroot and the general fish population data. Other topics will include eDNA testing in the Bitterroot, which is one of the new ways to identify invasive water species such as mussels. He'll also talk about the debate of barbless versus barbed hooks on trout.

It will be a fairly inclusive set of topics for Clancy.

The public is invited to the 7 p.m. meeting at the Hamilton Elks Lodge at 203 State Street in Hamilton. No admission charge.

The Trout Unlimited group has monthly public presentations concerning the Bitterroot and other watersheds. For more information, check their website. The members are getting ready for their annual kids' flytying classes - Bitterroot Buggers - and volunteers are always welcome.
