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。
