for Windowpane Flounder, Scophthalmus aquosus

Hippoglossoides platessoides


Sandy Sutherland (SJS) has been working with Windowpane Flounder since 2015. Whole otoliths viewed with reflected light, except for large fish (>30cm) which are cut in half and viewed with reflected light. Only samples from Georges Bank (GB) are currently aged.

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).
