[go] otolith mineralization

[camon at ebi.ac.uk]

Hi Jen,

I used to slice otoliths when I worked for the dept. of marine many moons
ago. You can read Otoliths like the rings of a tree to age fish. They are
used for growth determination and to determine fishing quotas.

I'm no expert on their mineralization but I think it happens throughout
their life.
