Chinook Salmon Scale Age Meeting

Location: Centennial Hall Egan Room in Juneau, Alaska
Date: April 2,3, 2014

The goal for this meeting was to bring together the primary Chinook salmon scale age readers from the Pacific Northwest to present their current methods and criteria for Chinook salmon scale age reading, discuss similarities and differences among methods, and jointly develop standards and quality control protocols that can be applied to Chinook salmon scale age reading in the Pacific Northwest.

The program shows a map of the area, workshop schedule, list of presentations, and participant contact information. Meeting materials can be found on the above tabs.

Chinook salmon scale age terminology with meeting participants' comments and revisions. The terminology list is designed to be a living document and is not meant to supersede agency-specific definitions.

The following is a summary of participant feedback.
