Strontium and barium in otoliths are mainly from ambient water where fish survives. These two ele-ments precipitate into otoliths crystal lattice or interstitial to substitute for calcium (Ca²⁺ ) in vaterite or aragonite. The precipitation of otoliths is controlled not only by biological regulatory, but also influenced by environmental factors, such as: element concentration, salinity, temperature of ambient water, food intake, etc. So there is a response relationship between element partition coefficient and ambient environment. The element concentration of ambient waters is the most significant one among all above mentioned environmental factors. In general, the element concentration in the otoliths is positively correlated to those in the ambient waters.
