. This study describes differences in scale characters between fanned, ranched and wild Atlantic salmon, Salmo salar h., and proposes a method to distinguish between the different groups. Six characters were found to differ: (1) smolt size; (2) smolt age; (3) transition from fresh water to salt water; (4) sea winter bands; (5) summer checks; (6) replacement scales. The combined use of these characters in a score system gave good separation between fanned and wild salmon, but not for ranched salmon.
