for Golden Tilefish, Lopholatilus chamaeleonticeps

Lopholatilus chamaeleonticeps


Katie Rogers (KR) has been working with Golden Tilefish since 2016; before that, the age reader was Nikole Jalbert (NJ). 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).
