AbstractYin-Tao Jia and Yi-Feng Chen (2011) Age structure and growth characteristics of the endemic fish Oxygymnocypris stewartii (Cypriniformes: Cyprinidae: Schizothoracinae) in the Yarlung Tsangpo River, Tibet. Zoological Studies 50(1): 69-75. The age structure and growth characteristics of Oxygymnocypris stewartii were studied using 430 specimens collected from the Yarlung Tsangpo River, Tibet. Our study on the length-frequency and age structure indicated that this population was suffering from unreasonable exploitation. The standard length (SL; mm)-body weight (W; g) relationship was W = 1.30 x 10(-5) SL3.002. The SL (L-t)- and weight (W-t)-at-age relationships were described by von Bertalanffy growth functions as follows: L-t = 877.4821[1 - e-(0.1069) ((t - 05728))] and W-t = 8805.1493[1 - e(-0.1069) ((t - 0.5728))](2.997) for females, and L-t = 599.3939[1 - e(-0.1686(t - 0.6171))] and W-t = 3091.3496[1 - e(-0.1686(t - 0.6171))](3.098) for males. It was observed that O. stewartii grew faster during the 1st 3 yr than other schizothoracines inhabiting the same region, and then its growth became slower. Our study also indicated that (1) O. stewartii's growth performance was relatively higher than those of other schizothoracines which inhabit the same region, and (2) its growth performance was relatively lower than those of other piscivore Cyprinidae fishes such as Cutter albumus Basilewsky which inhabit Wu and Cheng Lakes. Both of these characteristics might be related with its feeding habits and the environment in which it lives. Based on our results, we suggest that some regulations be promulgated as soon as possible. The government should publish a law to forbid fishermen from capturing O. stewartii. http://zoolstud.sinica.edu.tw/Journals/50.1/69.pdf
