耳石的

Once the otolith thickness age relationship was established, the simple process of measuring otolith thickness was as effective for determining the age of gray angelfish as the far more difficult process of sectioning and reading the otoliths.

一旦耳石厚度与年龄关系建立起来，一种简单的预测灰刺盖鱼年龄的方法就建立起来了，比传统的磨片读书方式容易多了。

With the study and application gradually elevation and improvement for otolith microchemistry of fish, corresponding study in the statolith of cephalopod become popular. Recently, microchemistry study is one of hot topics in fishery animal, and more and more scientists are interested in it as so much biology and ecology information was showed.

中文摘要：耳石是位于平衡囊内起平衡作用的一对钙化组织，它是头足类的加速度感应器，记录其生命周期内的生物和生态信息。

The leptocephalus were immersed in a tetracycline solution with a concentration of 350μg ml-1 to produce a fluorescent TC mark in the otoliths as the onset of the experiment. They were then reared under a constant condition of 25oC, 15psu and light cycle of 10D/14L for 16 days to investigate the ontogenetic somatic and otolith changes during metamorphosis.

标本携回实验室后，先以浓度350μg ml-1的四环素（Tetracycline， TC）萤光溶液标示，以便在耳石上留下萤光环记号当作实验的第1天，而后饲养在温度25℃，盐度15psu，光周期10D/14L下，直接观察变态过程的连续变化。

Two themes are discussed in this thesis: the age and growth of rockfish and the design of the computer-assisted detection system of otolith rings.

本文分为两个主题：许氏平鲉的年龄和生长以及耳石图像计算机识别系统的设计。

Increment formation was daily or near-daily through matemorphosis,and the otolith continued to grow during metamosorption.

轮纹的形成在变态期是每天的或者是接近每天的，而且耳石在变态阶段会继续增长。

The marks we found in the otolith provide the feasibility in studying the early life history events of the mullet.

利用这些耳石上的特殊记号，可以回推乌鱼初期生活史的成长史及洄游过程。

The semicircular canals are the primary sensors of angular motion, and the utricle and saccule contain the otolith organs, which sense both the linear motion of the skull and the orientation of the skull with re- spect to gravity.

头的倾斜可以引起耳石所致的毛细胞弯曲，后者将神经冲动通过前庭神经传送到大脑。

Sectioned otoliths displayed clear increments that were used to estimate fish ages.
