Age and Growth Program

Age and Growth Production Figures for 2008 through 1990

Before using any data from our website please read our disclaimer.

Select Year: 

 

Production Figure Terms

Raw age:  The first age generated by the age reader.  This includes samples to which an age range was assigned.

Update age:  Any sample that the first age has been reviewed.  An otolith will be reviewed if there is discrepancy between reader and tester or if there is a questionable age-length relationship.

Test age:  The age assigned by a second age reader or "tester".  Twenty percent of raw ages are examined by a second reader.

Unageable:  Samples that could not be given a single age or a reasonable age range due to physical characteristics of the otolith, collector error, or indistinguishable growth patterns.
