The influence of temperature on the fluorine and calcium composition of fish scales.
Proton microprobe studies of the scales of the kahawai (Arripis trutta) and the snapper (Chrysophrys auratus) showed non-linear changes in the fluorine to calcium ratio that increase with increasing temperature, but both species showed a different temperature sensitivity. Fluorine and calcium levels vary within years from summer to winter by up to 1000%, making fluorine and calcium levels good markers of seasonal events.
