Age & Growth Program
Total production figures were 15,593 with 3,727 test ages and 149 examined and determined to be unageable.
The Age and Growth Program has made several additions to its website
(http://www.afsc.noaa.gov/refm/age): 1) a table that supplies a brief history
of the ageing of groundfish species at the AFSC with a rough indication of the level of difficulty in producing
precise ages and 2) the otolith database which contains an inventory of aged otolith collections from RACE
surveys and the Observer Program and allows the used to query the database by species and region.
