Methods for scale-based age estimation

Salmon Scale Wiki provides a Chinook salmon scale age estimation reference created, edited, and updated by users across Alaska.

Salmon Scale Wiki was started in September, 2016 by Lorna Wilson, Rich Brenner, and Bev Agler as part of the Saltonstall-Kennedy Grant Program funded project "Chinook Salmon Scale-based Age Study." The purpose of this site is to provide a manual for Chinook salmon scale age estimation and to act as a scale pattern version of Wikipedia, a popular free web-based encyclopedia.

The thoroughness and accuracy of this Wiki depends on user contributions.


This project received funding under award NA16NMF4270252 from NOAA Fisheries Service, in cooperation with the Saltonstall-Kennedy Grant Program. The statements, findings, conclusions, and recommendations are those of the author(s) and do not necessarily reflect the views of NOAA Fisheries.
