Initials for each age reader are given. All samples were collected by the Northeast Fisheries Science Center (NEFSC). Stock indicates which stock area samples were taken from, Georges Bank (GB) or Gulf of Maine (GOM); if not specified, samples were from both areas combined. In tests where agreement is below 90%, bias indicates either the P-value of a Bowker’s test or ‘n/s’ (test not significant at the α = 0.05 level).
