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。

Otoliths remained steadily growing during metamorphoses, the number of otolith DGIs deposited after TC marks as consistant with the rearing days(p＜0.01) which validate the daily periodicity of the otolith increment deposition of Pacific tarpon leptocephali during metamorphoses. As for otolith microchemistry, Sr/Ca ratios in otolith of the fish decreased in accompany with metamorphosis, while Na/Ca ratios in otolith changed oppositely as Sr/Ca ratio.

TC萤光记号后新增的耳石轮数与饲养天数之间呈1：1的线性关系（p＜0.01），所以大眼海鲢的柳叶鱼在变态期间，耳石仍然维持一天一轮的日周性成长，变态开始发生时，耳石的轮宽急遽上升，耳石的Sr/Ca比急遽下降。

The trace element characteristics of entire otolith and the thermoluminescence characteristic can also be used to appraise the quality of water. Moreover, the trace element characteristics of otolith increments may be take a sign to dynamicly monitor the quality of lake.

通过耳石的全耳石元素特征和热发光特征可以对水质进行评价，而耳石的不同生长环带中的元素特征可以作为湖泊动态监测的一个标型。

In this paper, thermoluminescence characteristics of otoliths of the wild carps in the Baiyangdian Lake of Hebei Province and the Miyun reservoir of Beijing were studied, and the difference of energy gap between the fish otoliths in the two regions was analyzed.

In the past two or three decades, quite a few achievements have been made in the study of fish otoliths, but no advances in researches on the thermoluminescence characteristics of the fish otoliths have been reported in literature.

鱼耳石的主体由生命矿物文石组成，其研究在过去二三十年中已取得了不少成果，但是将热释光技术用于鱼耳石的研究未见报道。

Methods The otoconia of 18 guinea pigs were damaged by a high G force (10 Gy 5 min), and their utricle macula were observed by scanning electron microscopy at 1 h, 2 d and 8 d after the damage respectively. The elements of different kinds of otoconia were measured qualitatively and quantitatively by electron probe Xray microanalysis.

给予过载刺激(10 Gy 5 min)造成18只豚鼠耳石的损伤破坏，用扫描电镜（scanning electron microscopy，SEM）分别观察过载刺激后1 h、2 d、8 d时其椭圆囊囊斑，用X射线显微能谱分析技术(electron probe Xray microanalysis，EPMA)测量不同形态类别的耳石元素构成。

Several basic tenrts of otolith research have been questioned recently with regard to eel metamorphosis.specifically,some researchers have suggested that otolith increment formation is not daily,and otolith material may be resorped during metamorphosis.we conducted a rearing experiment to test the hypothesis that increment formation is daily and that the otolith continues to grow during eel metamorphosis.we marked the otolith of wild-caught leptocephali and reared these fish through metamorphosis.metamorphosis was characterized by a decreasing standard length,pre-anal length,and body depth accompanied by an increase in pigmentation and a change in behavior.

最近学者关注的鳗的耳石的研究的几个最基本的问题涉及到鳗的变形。尤其是很多研究者认为耳石的日轮沉积并非是每天的，耳石的材质可能是会在变态过程中被重吸收一部分。我们做了个养殖的实验来测试鳗鲡耳石的形成的每天一轮而且在鳗鲡的变态发育阶段耳石是在继续生长的。我们标记了野外捕捞的蠕鳗幼体，养过变态期。变态期是通过标准长度，肛前长和体高的减少和色素的减少以及行为的变化来定义的。

Daily-growth increment of otolith and growth of Japanese parrotfish were studied and research objects were taken from Zhoushan Fishries Research Institute in April 2009. Microscopic observation was performed on the growth of the otolith during the embryonic development of artificially fertilized eggs and the formation of the first daily growth increment on otolith of larvae.
