鱼类眼睛晶体信息分析与应用研究进展

Review of the information analysis and its application in fish eye lens

眼睛晶体作为鱼类的硬组织之一,具有结构稳定、耐腐蚀、易获取的特性,其含有大量的蛋白质,蕴含着丰富的化学信息,并在鱼类的年龄鉴定中得到了一定程度的应用。近年来,随着生物地球化学技术的不断创新与进步,鱼类眼睛晶体的微量元素、稳定同位素信息也越来越受到国内外学者的重视。本文将依据国内外学者的研究成果,从眼睛晶体的直径与重量、微结构、微量元素和稳定同位素等方面,对鱼类的年龄鉴定、栖息环境重建、摄食生态的追踪等方面的应用进行综述,并通过分析鱼类眼睛晶体的组成成分与生长模式,比较眼睛晶体与其他组织做稳定同位素分析的优势,着重归纳总结了眼睛晶体碳氮稳定同位素在鱼类生活史信息,尤其在摄食生态、栖息环境重建等方面的研究方法、应用现状及发展前景,为以后开展相关的研究提供参考。

As one of the hard tissues of fish,eye lens has the characteristics of stable structure,resistance to erosion,and easily accessible.It contains a large amount of protein,which records much chemical information,and has been applied to a certain extent in the age determination of fish.In recent years,with the continuous innovation and progress of geobiochemical technology,the trace element and stable isotope information of fish eye lens has been paid more and more attention to by scholars at home and abroad.Here,the application of determined age,habitat reconstruction and feeding ecological tracking were reviewed in terms of the diameter and weight,microstructure,trace elements and stable isotope of the eye lens,after analyzing the composition and growth pattern of fish eye lens and comparing the advantages of eye lens and other tissues for stable isotope analysis,the research methods,application status and development prospects for stable isotope of eye lens in fish life history information,especially in feeding ecological tracking and habitat reconstruction were summarizied to provide reference for future research.
