摘    要:为了摸清雅鲁藏布江特有种异齿裂腹鱼(Schizothorax oconnori)的游泳能力,以野生鱼种为实验对象,通过丹麦Loligo System公司的环形试验水槽测试了异齿裂腹鱼的临界游泳速度、突进游泳速度和持续游泳速度。结果显示,异齿裂腹鱼的临界游泳速度随体长的增大而增加,相对临界游泳速度随体长的增大而减小,其临界游泳速度与体长的关系为Y1=-39.369+13.23X-0.371X2+0.004X3(Y1是绝对临界游泳速度,X为体长)。突进游泳速度随体长的增加而近似呈线性递增趋势,而相对突进游泳速度随体长的增大而减小。在三个固定流速(60cm/s、80 cm/s、100 cm/s)下,初步确定60 cm/s为异齿裂腹鱼的持续游泳速度,80 cm/s、100 cm/s为耐久游泳速度。研究成果以期为青藏高原地区鱼类行为学的研究提供基础资料,为鱼道等过鱼设施的设计提供参考资料。

Abstract:In order to understand the swimming capability of endemic species Schizothorax oconnori in the Yarlung Zangbo River,a swimming tunnel was used to test the critical swimming speed,burst swimming speed and sustained swimming speed of wild S.oconnori.The results showed that the absolute critical swimming speed increased with the body length and the relational relationship was Y1=-39.369+13.23X-0.371X2+0.004X3(Y1 was cruising swimming speed,X was body length),while the relative critical swimming speed declined with the increase of body length.Absolute burst swimming speed increased with the increase of body length and the relation was approximately linearity,but the relative burst swimming speed declined with the increase of body length.Under the three current velocity(60 cm/s、80 cm/s、100 cm/s),results showed that the sustained swimming speed of the wild S.oconnori was 60 cm/s,and the endurance swimming speeds were 80 cm/s and 100 cm/s.This investigation may provide information for research on fish swimming capability and fishway design.
Keywords:Schizothorax oconnori  swimming capability  swimming speed  swimming behavior
