Wildlife Commission fisheries biologists are asking anglers to help them document the presence of gill lice — tiny, white crustaceans — that have been found on brook trout in several headwater streams of the Cullasaja River in Macon County. Biologists don’t know how widely distributed the gill lice are or the ultimate impact they may have so they’re asking any angler who catches a brook trout with gill lice to contact Jake Rash at 828-659-3324, ext. 225, or by email at [email protected].
