Otolith Wikipedia

Studying the trace elemental composition or isotopic signatures of trace elements within a fish otolith gives insight to the water bodies fish have previously occupied. Fish otoliths as old as 172 million years have been used to study the environment in which the fish lived.

NPAFC Working Group on Salmon Marking

To find a thermal mark on an otolith, fish must be sampled, then their sagittae otoliths (the largest of the 3 pairs) are removed. The left sagittae otolith is glued to a glass slide with thermoplastic cement then ground on a grinder. When the center of the otolith is reached, it is examined under a microscope for the presence of a thermal mark.
