摘要：

We have measured the distributions of some of the elements in in otoliths and scales from several species of teleost (bony) fish, with the aim of learning more about the environment of a fish at different stages in its life, and testing the validity of present methods for determining the age of a fish. The ratio of strontium to calcium in successive layers of an otolith is extremely sensitive to water temperature, so it is possible to trace the temperature history of the fish, probably including seasonal variations. The distributions of calcium and fluorine in scales differ strikingly between species and sufficiently in a single scale to suggest that environmental information may be captured there as well.
