To elucidate the relationship between otolith microstructure and microchemistry and the life history events of the grey mullet Mugil cephalus in the early stage, the daily growth increments, growth check, Sr/Ca ratios and trace elements in otoliths of the juvenile mullets collected from the four estuaries from NE to SW Taiwan coast from 1996 to 2004 were examined by using the light and electron microscopes, electron probe microanalyzer and laser-ablation inductively coupled plasma mass spectrometry. A transition check was found in otoliths of all mullets.

为了阐明乌鱼耳石微细构造、微化学与其初期生活史事件之关系，本研究於西元1996年至2004年在台湾东北至西南沿岸的四个河口域进行乌鱼稚鱼的采样，然后利用光学及电子显微镜、电子微探仪及雷射熔蚀-感应偶合电浆质谱仪分析稚鱼耳石的日周轮、锶钙比及微量元素组成之变化。

Distribution of biogenic silica content in surface sediments from deep water areas showed that it could not only reflect the paleoproductivity of siliceous micropaleontology in surface waters, but also indicate the strong or feeble upwelling. Thus, it was further confirmed that using biogenic silica content in sediments to trace upwelling and its change was effective and reliable. The analyzed result showed that radiolaria and poriferous specula have more contribution for biogenic opal, comparing with diatom in surface sediments from the northern studied area, probably owing to the diatom dissolved easily away and eaten by other organisms with little effort.

深水区表层沉积物中生物硅的含量分布表明，其不仅能反映出表层水体中硅质生物的古生产力水平，而且还能指示上升流的强弱，从而进一步证实了利用沉积物中生物硅含量来追踪上升流发育和变化的有效性与可信度研究结果还显示，在研究区域中北部表层沉积生物硅中放射虫和海绵骨针较硅藻占有更大的比重，这可能是由于硅藻易被溶解并易被其他生物体摄食的缘故。
