Scup, Stenotomus chrysops
Nicole Calabrese (NC) has been working with Scup at NOAA since 2013, and has 8 years of prior experience. Prior to 2013, the age reader was Daphne Cassidy (DC, retired). Sectioned otoliths are viewed with reflected light.
In tests where agreement is below 90%, bias indicates either the P-value of a symmetry test or ‘n/s’ (test not significant at the α = 0.05 level). The Evans & Hoenig test was used to test bias starting 1/2022; prior to that, a Bowker's test was used.
