摘　　要：对采自中国南海东沙群岛海域的135尾鲹科鱼类(长体圆鲹Decapterus macrosoma、泰勃圆鲹D.tabl、无斑圆鲹D.kurroides、竹䇲鱼Trachurus japonicus、短吻丝鲹Alectis ciliaris、高体若鲹Caranx equula、脂眼凹肩鲹Selar crumenophthalmus)的矢耳石形态特征进行研究。7种鲹科鱼类矢耳石整体形态呈长椭圆形、四边形、半圆弯钩形等多种形态,耳石周围存在脊突,均有基叶和听沟发育,听沟从耳石前部的主间沟部分一直延伸至耳石后部。研究结果表明,7种鲹科鱼类耳石形态特征种间差异明显,通过耳石形态建立的系统分类检索,以及应用聚类分析识别耳石形态效果显著。这将为鲹科鱼类鱼种识别及系统分类提供参考资料。The morphological characteristics of sagittal otoliths of 135 individuals of Carangidae(Decapterus macrosoma,D.tabl,D.kurroides,Trachurus japonicus,Alectis ciliaris,Caranx equula,Selar crumenophthalmus)collected from the Dongsha Islands in the South China Sea were studied in this paper.The entire morphology of sagittal otolith of 7 species of Carangidae was long oval,quadrilateral and semicircular curved hooked.There were knobs around the otolith with the development of rostrum and sulcus.The sulcus extends from the excisural notch of the anterior part of otolith to the posterior part of otolith.The results show that the morphological characteristics of otoliths of 7 species of Carangidae were obviously different among species.The systematic classification and retrieval table established by otolith morphology and the application of cluster analysis were effective in identifying otolith morphology.This study will provide some reference for the stock identification and systematic classification of Carangidae.
