Fish otoliths Analysis
The tissue of a living organism is mainly comprised of soft tissue and hard tissue. Among the hard tissues bone tissue is mainly composed of calcium carbonate. There is a strong relationship between the metal elements present in the hard tissue of an organism and the development (growth) of that organism. Obtaining the concentration and distribution of these metal elements in hard tissue helps us to understand the living environment and health condition of an organism This article describes an analysis of the metal elements present in fish otoliths.
