Development, evaluation and monitoring of new age readers for 4VWX5Zc pollock
By J. Neilson; C. Nelson; P. Perley
Abstract
The procedure for training, evaluating and monitoring new age readers for the pollock (Pollachius virens) resource occurring in Maritime waters is described. Training was mainly through review of interpretations of age provided by the previous age reader, enhanced by the use of annotated videotape images which provided an archive of previous age determinations. Evaluation and monitoring was completed by a range of procedures designed to measure within-reader precision and among-reader agreement. It was concluded that both age readers had achieved suitable levels of competence, and production ageing for this resource could commence.
