耳石在鱼类年龄与生长研究中的应用

Application of Otolith in Studies on Fish Age and Growth

有关鱼类耳石的研究已有100多年的历史,目前已形成一个相对独立的研究领域,在多个研究层面上深入开展,但年龄与生长至今仍然是鱼类耳石研究的主要方面。本文分别从耳石的年轮、日轮和重量方面,介绍了当前耳石在鱼类年龄与生长研究中的应用与发展。我们认为,对耳石日轮的研究仍将会是耳石研究的重要方向;相关研究将会逐渐由个体尺度向种群尺度发展,并可为渔业资源的可持续利用提供科学依据。

With more than 100 years of history,studies on fish otolith have become a special field in the ichthyology,and fish age and growth in the studies is still one of the major themes. We reviewed the past research of otolith on fish age and growth from three aspects： otolith’s annual rings,daily increments and weight. Especially,the otolith daily increments’study has been and will continue to be the most important subject on the research of fish otolith. In our opinion,studies related to otolith will develop from individual to population gradually. Meantime,the sustainable use of fisheries resources will benefit a lot from the otolith study.
