Pomatomus saltatrix


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 Bowker's test or ‘n/s’ (test not significant at the α = 0.05 level).
