摘　　要：根据分别采集于贵州清水江和都柳江的共计249例标本,观察了光倒刺鲃鳞片、主鳃盖骨、匙骨、脊椎骨4种材料的年轮特征。结果表明,光倒刺鲃这4种年龄鉴定材料的年轮特征各不相同,以鳞片年轮特征最为清晰。根据71例光倒刺鲃标本的体长、体重、鳞径资料,拟合出其体长与鳞径的关系。光倒刺鲃的生长拐点年龄为11.13龄,体长为679.12 mm,体重为7 483.87 g。The annuli on scale, opercular, cleithrum, vertebra of Spinibarbus hollandi were observed carefully on the basis of 249 specimens collected respectively from the Qingshui River and the Duliu River in Guizhou, China. The result shows that the annuli on scale, opercular, cleithrum, vertebra were all different from one another. The inflexion age of Spinibarbus hollandi is 11.13, body - length is 679. 12 （mm） , body - weight is 7 483.87 （g）.
