 Data as of 2010

*Sample sizes are probably insufficient to establish max age and natural mortality rate estimates for these species.

 

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

  Click on a fishes scientific name to see the five oldest samples. Click on it again to hide this information.

  Maximum age data is from ages generated between 1990 and 2010 except Pacific cod, which is limited to collections read after 2000.

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