Once the otolith thickness age relationship was established, the simple process of measuring otolith thickness was as effective for determining the age of gray angelfish as the far more difficult process of sectioning and reading the otoliths.

Using high performance liquid chromatography, X-ray diffraction and Fourier transformation infrared spectra, the authors characterized the sorted proteins from different otoliths. It is found that the three types of proteins in lapillus and asteriscus have different characteristics, and such differences may be responsible for different kinds of crystalline state in calcium carbonate.
