A TECHNIQUE FOR PRODUCING AND MOUNTING OTOLITH WAFERS FOR AGE DETERMINATION Wafers (sections of fish otoliths frequently offer the only reliable way to determine age. but since the cost of producing wafers is greater than the cost of processing scales or whole otoliths, they should be resorted to only as a check on other "aging" methods or if reliable alternatives are not a Available. "Wafering" for age determination is required when otoliths cleared in anise oil or other agents are too opaque to read, when precipitous marginal escarpments prevent observation of the most recent rings, and when the density of rings prohibits accurate counting. The mounting technique described herein was developed for use pri- marily with a hydraulic-ally controlled, gravity down-feed, diamond.
