The Alaska Fisheries Science Center Age and Growth Program's guide to the age determination of key groundfish species from Alaskan waters describes techniques specific to the age determination of commercially and ecologically important species studied by the Program. The manual also provides general background information on otolith morphology, dissection, and preparation, as well as descriptions of methods used to measure the precision and accuracy of our age estimates.
Supplementary Material to the Age Determination Manual of the Alaska Fisheries Science Center Age and Growth Program
Additional information not published in NOAA Professional Paper 13 has been provided here in a web-based format. Most of the chapters listed below describe the age determination methods of non-commercial species or species for which age estimates have not been validated. This supplementary information also includes a description of our database and lists of supplies and references that may be useful to other age determination laboratories.
Due to the evolving nature of age determination science, some of the information presented here may change as new methodologies are developed over time. Furthermore, the Age and Growth Program is currently investigating the age determination of previously unstudied species, and as such it can be expected that new species chapters will be written in the future. Chapters which have been updated or added will be noted accordingly.
