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。

Anguillarum isolates, while 94.3% and 91.9% nucleotide identical to L. pelagius and Photobacterium damselae respectively. MP analysis showed that ayu-H080701 shared 97.6%-98.8 % amino acid sequence identical to L. anguillarum isolates, while lower than 75.6 % to other bacteria. Phylogenetic analysis showed that ayu-H080701 grouped constantly with L. anguillarum isolates. The biochemical, physiological tests and sequence analysis all strongly supported the identification of the pathogen causing ayu vibriosis in Ninghai country, China, as an isolate of L.
PCR扩增检测表明,细菌16S rRNA 基因通用引物和鳗利斯顿氏菌MP基因特异引物均能扩增到预期大小的特异性条带。ayu-H080701与鳗利斯顿氏菌16S rRNA基因核苷酸序列同源性最高,为99.4%~99.5%,与同属的海弧菌和美人鱼发光杆菌分别为94.3%和91.9%;ayu-H080701与鳗利斯顿氏菌MP氨基酸序列同源性高达97.6%~98.8 %,与其它弧菌科成员则低于75.6 %,系统进化树分析也揭示ayu-H080701与鳗利斯顿氏菌进化相关性最高。
