Title: AFSC/REFM: Alaska groundfish AGEDATA database,1982 to present
Short Name: AFSC/REFM: Alaska groundfish AGEDATA database,1982 to present
Status: In Work
Publication Date: 2016-05
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
