The Loughs Agency has confirmed the detection of a “limited number” of escaped rainbow trout from an aquaculture facility in the Foyle area.
Investigations are being conducted by inland fisheries officials from Northern Ireland’s Department of Agriculture, Environment and Rural Affairs (DAERA).
Anglers in the area who catch rainbow trout are advised not to release them back into the river and, if possible, to retain samples for Loughs Agency fishery officers who will collect them on request at +44 (0) 28 71 342100.
