| 摘 要： | 软骨鱼类(鲨、鳐和银鲛类)多位居海洋食物网的顶端或近顶端, 通过下行效应调控海洋生态系统结构和功能, 多为生态系统中的关键性物种。脊椎骨是软骨鱼类支撑身体的重要硬组织, 其生长贯穿整个生活史, 主要应用于鉴定年龄。随着微化学技术的兴起, 并结合脊椎骨轮纹的特殊结构, 可进而掌握鱼类整个生活史中摄食及洄游信息。目前, 国内外基于脊椎骨的微化学研究主要集中在稳定同位素和微量元素分析, 并已取得一定的进展。本文在归纳国内外应用脊椎骨在软骨鱼类生长、摄食及洄游中的应用案例基础上, 着重分析了脊椎骨应用于年龄鉴定及校正、摄食及洄游等核心问题上的研究现状和发展前景, 以期为今后学者展开基于软骨鱼类脊椎骨的相关研究提供参考。

| Abstract: | Cartilaginous fishes (sharks, rays, and chimeras) mainly occupy the highest and median trophic position of the marine food web. As top predators, they play key roles in marine ecosystems via top-down control. Vertebrae are the hard tissues supporting the bodies of cartilaginous fishes, which continue to grow throughout the life span and can be used to track age. With the development of microchemistry and increased knowledge of the special structure of vertebral bands, the feeding and migration patterns of the entire life history of fish can be elucidated. Recently, research on the microchemistry of vertebrae using stable isotope and trace element analysis has made great progress towards answering questions regarding the biology and ecology of cartilaginous fishes. In this paper, the studies on age, growth, feeding habits, and migration using the vertebrae of cartilaginous fishes were reviewed, focusing on age identification and data validation, feeding ecology, and migration routine prediction with the aim of providing references for future biological and ecological research on cartilaginous fishes using vertebrae. |
