Full Citation Examples
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.
Distribution Information
There are no legal restrictions on data from specimens collected by surveys, however information from fishery observer collections are regulated under the Magnuson-Stevens Fishery Conservation and Management Act.
User must read and fully comprehend the metadata prior to use. Applications or inferences derived from the data should be carefully considered for accuracy. Acknowledgement

| Abstract: |
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. |
| Purpose: |
The AGEDATA database houses fish ages that were generated for stock assessments and age and growth research. |

Data Quality
| Accuracy: |
Quality control in ageing methods is documented in "Quality control of age data at the Alaska Fisheries Science Center" which is available at the following website adress: http://www.afsc.noaa.gov/refm/age/docs/MF04141.pdf |
|---|---|
| Completeness Report: |
Not applicable. |
| Conceptual Consistency: |
Age data from 1990 to present followed similar database integrity measures, but ages generated from 1982 to 1990 were imported from a Burroughs system with variable levels of confidence. |
| Quality Control Procedures Employed: |
Quality control in ageing methods is documented in "Quality control of age data at the Alaska Fisheries Science Center" which is available at the following website adress: http://www.afsc.noaa.gov/refm/age/docs/MF04141.pdf |
