The database contains over 900,000 observations of biological and collection data from survey and observer fish specimen collections spanning from 1976 to 2015. Primarily the species aged are comprised of commercially important species of Alaska and the west coast such as walleye pollock, Pacific cod, rockfish, sablefish, and flatfish, although smaller numbers of other species are included as well such as skates, sculpins, and forage fish species. Specimen data includes fish age estimates, fish length, sex, weight, collection coordinates, date of collection, fish ageing methodologies, age reader information, and ageing structure descriptions. The AGEDATA database houses fish ages that were generated for stock assessments and age and growth research. underDevelopment Short, Jon jon.short@noaa.gov pointOfContact Chamberlin, Derek 206-526-4148 7600 Sand Point Way NE Seattle WA 98115-6349 USA derek.chamberlin@noaa.gov custodian asNeeded Fishery-Dependent Tracked Asset theme Fisheries age growth juvenile migration otolith photo theme fall spring summer temporal Alaska Aleutian Islands Bering Sea Bristol Bay Gulf of Alaska Prince William Sound Shelikof Strait Shumagin Islands place DOC/NOAA/NMFS/AFSC > Alaska Fisheries Science Center, National Marine Fisheries Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2017-04-24 publication 8.5 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.
