| 摘 要： | 基于鱼类营养级统计软件TrophLab,对分布于雅鲁藏布江中游的6种高原土著鱼类异齿裂腹鱼(Schizathorax oconnori)、拉萨裂腹鱼(Schizothorax waltoni)、双须叶须鱼(Ptychobarbus dipogon)、拉萨裸裂尻鱼(Schizopygopsis younghusbandi)、尖裸鲤(Oxygymnocypris stewartii)和黑斑原鮡(Glyptosternum maculatum)进行了营养级估算。结果显示:6种研究对象的营养级范围为2.28～4.30,其中尖裸鲤营养级水平最高,异齿裂腹鱼营养级水平最低。

| Abstract: | Trophic levels were estimated for six plateau fish species from the middle Yarlung Zangbo River by TrophLab software based on published diet information,including Schizathorax oconnori , Schizothorax waltoni , Ptychobarbus dipogon , Schizopygopsis younghusbandi , Oxygymnocypris stewartii and Glyptosternum maculatum .The results showed that trophic levels of six research objects were ranged from 2.28 to 4.30.The highest trophic level was found in O.stewartii and the lowest trophic level was found in S.oconnori . |
