Dear Carol,

Some years back we supplied a Bright 5040 microtome for sectioning
undecalcified otoliths in Cod, I can give you the  contact details in the UK
if this would help.

Subject: fishheads & boneheads - otolith aging


Greetings Histonetters:

Has anyone done aging of fish on decalcified otoliths (earbones) embedded in
paraffin?  I am concerned that I won't see the growth rings after
decalcification.  If it can be done, how should the otolith be oriented for
sectioning?  Is H&E a good stain?  I have a fisheries biologist who used to
do histo thinking that this might be an easier method than grinding the
otoliths.  He wants to do this on striped bass (Morone saxatilis).

Thanks for your help.

Regards -
Carol
