The Incidence of Regenerated Scales Among Fraser River and Skeena River Sockeye Salmon

Scales of 4 and 5 year-old Skeena River and 4 year-old Fraser River sockeye of the 1963 brood year were examined for the incidence of regenerated scales. For the Skeena and Fraser 4 year-old sockeye the incidence of regenerated scales was 11.1% and 8.2%, respectively. For Skeena sockeye, the incidence of regenerated scales was 8.2% and 24.0%, respectively between 4's and 5's. Detailed examination of the regenerated scales indicated that most scales were lost early in the first ocean year, after the fish had left freshwater.
