Eric Robillard (ER) has been working with Bluefish since 2015; before that, the age reader was Nicole Calabrese (NC). Sectioned otoliths are viewed with transmitted 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.
