AFSC Maximum Ages Encountered

AFSC Maximum Ages Encountered

Maximum age data is from ages generated between 1990 and 2020 except Pacific cod, which is limited to collections read after 2000.

Natural mortality (M) is estimated using the method outlined by Hoenig (1983) which uses maximum age to estimate instantaneous mortality.
