两种标记方法对异齿裂腹鱼幼鱼的标记效果研究
|
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。
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 was10. 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 shortterm tagging methods for juvenile S. o'connori.
