The annuli on scale,opercular,dorsal fin spine,vertebra and cleithrum of Tor(Folifer) Brevifilis Brevifilis Peter were observed carefully and also the age of the species was diagnosed on the basis of 316 specimens collected respectively from the Qingshui River and the Duliu River in Guizhou,China.The result shows that the annuli on scale,opercular,dorsal fin spine,vertebra and cleithrum of Tor(Folifer) Brevifilis Brevifilis were all different from one another.Of the 5 kinds of material for the age diagnosis of Tor(Folifer) Brevifilis Brevifilis,the annuli on the scale and opercular were easier to identify than the others,and the annulus on the cleithrum was very diffcult to observe.Age agreement based on the scale and opercular was 92.1%. The scales of Tor(Folifer) Brevifilis Brevifilis formed more annuli in May,August and October than any of the other months withina year.Among the 5 kinds of material,the scale is the best material for the age diagnosis of [WTBX]Tor(Folifer) Brevifilis Brevifilis and the opercular and dorsal fin spine both are important auxiliary material for the age diagnosis of the species.
