| 中文摘要: |
| 本研究采集中国沿海常见五种鲳属鱼类并对其耳石进行系统的多元形态学描述与比较。耳石形态在整体轮廓、边缘以及前部表现出明显的种间差异，展现了耳石形态的种内特异性。随着基因隔离与种间分化，鲳属鱼类耳石也逐渐变薄且基叶、翼叶更为发达。上述观察到的种间耳石形态差异与鱼体本身生活的水层以及温度联系紧密。96.6%的判别成功率也证明鲳属鱼类耳石显著的种间差异，表明形态学方法可以作为鲳属鉴别的有效手段之一。 |
| 英文摘要: |
| Sagittal otoliths morphology were compared to identify five Pampus species of the Chinese coast (Chinese pomfret Pampus chinensis, grey pomfret P. cinereus, southern lesser pomfret P. minor, plumage pomfret P. punctatissmus, and Pampus sp.). Otoliths demonstrated species-specific characteristics with noticeable differences in overall shape, margin and anterior region among species. With species divergence, otoliths get thinner following further developed rostrum and anti-rostrum. Interspecies variation in otolith could associate with experienced different temperature and water column. The discriminant analysis presented a high classification accuracy of 96.6%, which confirms the inter-specific distinction of otolith shape and enable the species identification. |
