6. Trim excess mounting media around the otolith using an IsoMet® Precision Saw with a 15LC blade. This will save preparation time by reducing the surface area of epoxy that needs to be removed in the grinding process. A parallel cut will also insure that the correct polishing plane is established.
Preparing sections for polishing is a two-stage process. First the otolith is ground down to the desired plane and polished to eliminate any surface irregularities. This is a painstaking process, the grinding plane must be constantly checked to avoid overshooting the nucleus or wearing away the otolith edges.
Otolith Microstructure Preparation. ... The key step in otolith polishing is checking where the polishing plane is in relation to the plane of the growth increments (this process is shown in the paired images at the bottom of this page). ...

Otolith preparation is a very time consuming process. It requires a microscope slide, some type of thermoplastic glue, and a means to section the otolith either by grinding with sand paper or a diamond blade wet saw. The idea is to grind the otolith from either side until a thin section containing the nucleus remains. Depending on a

Grinding and polishing is done using a grinding machine consisting of a rotating mechanism, an otolith-holding assembly unit and grinding and polishing discs. For rough grinding the disc is fitted with abrasive material of 30 um grain size. For fine grinding an abrasive film of 3 um is used.
otolith processing industry have estimated that over one million otoliths are aged annually (Campana & Thorrold, 2001). This represents a large investment in both facilities and labour in removing, grinding, polishing and then reading otoliths to retrieve the information carried within the micro-structure of the otolith.
