| 摘要: |
| 异齿裂腹鱼（Schizothorax oconnori）是仅分布于雅鲁藏布江中游的高原特有鱼类。本研究在室内水泥池条件下探讨了可见植入荧光（VIE）标记和T型标志牌对异齿裂腹鱼幼鱼的短期（30 d）标记效果。共设置3个处理组，分别为VIE标记组、T型标志牌组和对照组。VIE标记的标记部位为试验鱼的头部表皮，T型牌的标记部位为试验鱼的背鳍基部。试验期间的水温为10.1~11.7 ℃，溶解氧为3.65~7.54 mg/L。结果显示，各标志处理组在试验期间没有显著生长，各组间的全长也没有显著性差异。VIE标记组、T型牌组和对照组的平均存活率分别为95.8%、92.0%和97.5%。VIE标记组和T型牌组的平均标志保持率分别为100%和88.95%。本研究表明，VIE标记是适宜异齿裂腹鱼幼鱼的短期标记方式。 |

| Abstract: |
| Schizothorax o’connori is an endemic plateau fish species and mainly distributes in the middle the Yarlung Zangbo River. A 30-day tagging trial was conducted to compare the tagging effects of visible implant elastomer (VIE) tags and T-bar tags on juvenile S. o’connori under cement tank conditions.The experimental fish were individed into three groups, including VIE group, T-bar tags group and the control group. The VIE tags were tagged into the head skin and the T-bar tags were tagged into the base of the dorsal fin. During the experimental period, the water temperature was 10.1~11.7 °C, and the dissolved oxygen was 3.65~7.54 mg/L. The results showed no significant individual size differences before and after the experiment, and also no significant differences among groups. The mean survival rate of VIE group, T-bar group and control group were 95.8%, 92.0% and 97.5%, respectively. The mean tag retention of VIE group and T-bar group were 100% and 88.95%, respectively. The present study indicate that VIE is suitable for short-term tagging methods for juvenile S. o’connori. |
