Gshad are intolerant of low doses of rotenone. A local state park was treated a year ago with rotenone at a dosage where it only affected the Gshad.

Another local lake had them bucket stocked. The LMB aren't large enough to prey on the adults, so the Gshad population exploded. The last gill net survey the DNR did showed 60% of the biomass to be Gshad.
