Anglers are being warned to kill any crayfish they come into contact with. It comes after the non-native American Signal Crayfish was found for the first time in the River Nith in Dumfries.
The invasive species kills young fish and destroys natural habitats. Fishermen are now being asked to kill the crayfish if found and to take extra care when cleaning their fishing equipment and clothing to prevent eggs being spread.
