Cross-sectional structure and validation of the timing of annulus formation in otoliths of the Antarctic fish Notothenia coriiceps Richardson (Nototheniidae) ...
To validate the timing of annuli in otoliths of immature Notothenia coriiceps Richardson, a time-series of samples were taken over a complete year. Light and scanning electron microscopy (SEM) techniques were used to examine the structure of sectioned otoliths. Six growth regions were identified in...
