The genetic mineralogical characteristics of fish otoliths and their environmental typomorphism
Otolith is a typical biomineral carrier growing on insides of fish skull with prominent zoning structure formed by alternating layers of protein and calcium carbonate around the nucleus. The zoning number and the thickness of the rhythmic zone can reflect the age and the growing velocity. The δ18O values of the calcium carbonate are indicators of the temperature of the water where the fish lives. The...
