Removing ear bones

Removing ear bones

The otolith or ear bone of a fish can be measured to determine its age. The bone is cut into cross-sections and the growth rings, like those of a tree, are counted. Here, scientist David Banks removes an otolith from an orange roughy. The students in the background are being trained how to do this, as they are to work as scientific observers on fishing vessels.
