摘要

PIXE was adopted for analysis of trace elements in otoliths of anadromous fish, masu salmon Oncorhynchus TIUXSOU ntasou and araago salmon 0. mason ishikawae. Mn. Zn and Sr were detected in order of ppm. Two different types of spectra were obtained from masu salmon otoliths. The concentrations of Sr and Zn in the two types were quite different. The difference seems to be a result of the difference in periods when the individuals stayed in freshwater environment until they were caught. Amago salmon otoliths contain significantly less Sr than masu salmon otoliths. It is considered to be due to different migration pattern between the two subspecies. Anadromous fish generally experiences freshwater and sea water environment in its migration. Trace elemental concentrations in sea water is quite different from those in freshwater. The environment, which varies along with the migration, would affect the incorporation of trace elements into otoliths of anadromous fish.
