Abstract: This project closes out the Trustee Council's support for development of otolith mass marking as a technology for identification of hatchery pink salmon returning to Prince William Sound. The otoliths of all pink salmon reared at Prince William Sound hatcheries were thermally marked in the fall from 1995 through 1998. Blind tests were conducted to determine the ability of otolith readers to successfully determine the origin of randomly selected otoliths. During pink salmon commercial fisheries, approximately 100 otoliths were processed from each fishery opening to estimate stock composition. Generated estimates were provided to fishery managers within 36 hours of the closure of a fishing period. In post-season analysis, a Bayesian dynamic sample size allocation scheme was invoked to maximize sampling efficiency.
