摘    要:鱼类年龄鉴定是渔业资源评估的基础内容,经过长时间的发展,众多的方法被应用到这一领域。综述了目前应用较广泛的一些年龄鉴定方法,包括硬组织鉴定法和长度分析法两大部分方法,并分析了它们的优点和缺点。目前,鱼类年龄鉴定工作中存在的主要问题有:鉴定方法的精确度不高;鉴定方法多数较冗繁,耗时耗力;鱼类年龄鉴定未经标准化。有鉴于此,有必要对各种鉴定方法进行校验。介绍了几种常用的年龄校验方法,并对其进行了分析。

关 键 词:  年龄鉴定  耳石  体长频率  年龄校验

Abstract:Fish age determination plays an important role in the fish stock assessment.Now,many methods have been applied in this field.This paper reviewed the popular methods used in age determination,including the use of hard tissue and length frequency.Main drawbacks of these methods were concluded as follows:(1)Accuracy of fish age determination methods should be improved.(2) Most age determination methods were tedious and time consuming.(3) In many cases,fish age determination methods lack standardization.Consequently,aging methods should be validated in some methods,which were introduced in the third part of this paper.
Keywords:Fish  age determination  otolith  length frequency  age validation
