摘要:

南极冰鱼在南极海洋生态系统物质与能量循环中起着至关重要的作用。作为“白血鱼”,其科学研究意义和商业价值也为全球所关注,但其年龄与生长研究仍存在较多的不确定性。为此,本文综述了国内外近50年来南极冰鱼年龄与生长的研究进展,概述了南极冰鱼基本分类及其在南极海域的地理分布。在总结南极冰鱼年龄与生长研究的基本方法(包括渔获物体长频度法及钙化组织分析法等)的基础上,着重对南极冰鱼耳石处理及研究进行了归纳,通过耳石前处理(直接观察、燃烧和切割打磨)和轮纹鉴定等,对耳石研究中的耳石鉴龄方法、耳石形态学及耳石日轮等做了总结。通过总结南极冰鱼年龄与生长研究方面的困难和不足,如幼鱼耳石的处理方式及首轮形成的时间等,对今后中国开展南极冰鱼年龄与生长研究提出了展望。

Abstract: Antarctic icefish plays a significant role in the matter cycle and energy flow for Antarctic ecosystem. As a “white blood” fish, its scientific significance and commercial value has been concerned worldwide, but there exist many uncertainties in studies on age and growth of Antarctic icefish. Therefore, the present paper reviewed the research progress of age and growth of Antarctic icefish over the past 50 years, and summarized its classification and general geographical distribution in the Antarctic waters. Based on summarizing the basic methods on age and growth of Antarctic icefish, including length frequency analysis and analysis on calcified structures, this paper put the emphases on processing and estimating the otolith of Antarctic icefish species, and summarized age estimation, morphological feature and microstructure of otolith though preprocessing (direct observation, burning, and sectioning and polishing) of otolith and ring identification on sectioned otolith. Through summarizing the problems and deficiencies, such as the processing of juveniles’ otolith and forming time of first ring, on age and growth estimation of Antarctic icefish species, future research directions were prospected.
