Initials for each age reader are given. All samples were collected by the Northeast Fisheries Science Center (NEFSC). Structure indicates which age structure was used: either Scales, Otoliths, or a combination of both (S+O); one test was conducted to determine comparability of the two structures. 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).
