Trace element in fish otoliths were analyzed in 1996 to estimate the life histories of fish in derectly. In 1997, we tried to measure life histories of fish directly by means of micro-data tags in parallel with trace element analysis. The results of trace element analysis indicated that most available element is Sr in salmon otolith. This element especially available to understand the temporal period of salmon when swimming down to the sea side from river or swimming up from the sea to river to spawn, since Sr soncentration in sea water is higher 100 time than the fresh water. And Sr concentration in the otolith is directly influenced by the concentration in environmental water. The micro-data tag experiment was carried out using young yellow tail fish in the period of October and November at the Sagami Bay in 1997. The 12 tags were recovered from the experimental fish and analyzed their data.

1996年对鱼类耳石中的微量元素进行了分析，以直接估计鱼类的生活史。在1997年，我们试图直接测量鱼类的生活史，通过显微数据标签与微量元素分析并行。微量元素分析结果表明，鲑耳石中有效态元素以Sr为主。由于海水中Sr的浓度比淡水高100倍，因此，该元素特别适用于了解鲑鱼从河流游到海边或从海边游到河流产卵的时间周期。环境水体中Sr的浓度直接影响耳石中Sr的浓度。1997年10月和11月在相模湾用幼黄尾鱼进行了微数据标记实验。从实验鱼中回收12个标签并分析它们的数据。
