AFSC/REFM: Alaska groundfish AGEDATA database,1982 to present

The AFSC AGEDATA database is a collection of historic and ongoing fish ageing efforts by the Alaska Fisheries Science Center's Age and Growth Program from 1982 to present. 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.
