Acadian Redfish, Sebastes fasciatus
Image
Christine Kircun (CK) has been working with Acadian Redfish since 2012. Sectioned otoliths are viewed with transmitted light, except for small fish (<20 cm) which are cut in half and 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.
