| 摘 要： | 年龄与生长是渔业基础生物学研究的重要内容。体长频度法估算头足类的年龄并不可靠,然而利用硬组织来研究头足类的年龄和生长是最为有效的方法之一。角质颚作为头足类少数硬组织之一,具有结构稳定、耐腐蚀以及信息储存良好等特点而受到国内外学者的广泛关注。从角质颚的长度、角质颚生长纹的观察、初始纹的形成、生长纹周期性的证实以及日龄鉴定等方面综述了角质颚在头足类年龄和生长方面的研究进展。分析认为,尽管角质颚在头足类的年龄与生长的研究中已取得一定的进展,但是在利用生长纹鉴定年龄的方面还有所欠缺,较为成功仅为真蛸(Octopus vulgaris)和玛雅蛸(O.maya),缺乏对其他头足类种类的研究,需要在以后的研究过程中给予关注。

| Abstract: | Determination of age and growth is one of important things in the fishery biology study. Length-frequency has been thought not suit for cephalopod age determine, while hard tissue is one of the most effective ways to study their age and growth. Beaks as one of the few hard structure of cephalopods is increasingly popular for its high stable-morphology and erosion resistance as well as good information storage. In this study, we reviewed progress in the age and growth of cephalopods based on beak length, increments, formation of the first increments and age validation and determination. The result shows that some problems still exist in age identifying, that is studies only focused on Octopus vulgaris and O. maya, which should be solved in the recent future although a certain progress has been made. |
