中文摘要:
      为了探究大渡河上游典型鱼类的游泳能力,本研究以短尾高原鳅(Triplophysa brevicauda)、齐口裂腹鱼(Schizothorax prenanti)以及重口裂腹鱼(Schizothorax davidi)作为研究对象,使用自制Brett-type鱼类游泳能力测试水槽对3种鱼类的临界游泳速度以及突进游泳速度进行测量。实验结果表明:(1)3种实验鱼的绝对临界游泳速度关系为:短尾高原鳅(体长:9.92±1.15,临界游泳速度:0.91±0.13)<齐口裂腹鱼(体长22.01±5.17,临界游泳速度:1.09±0.35)<重口裂腹鱼(体长:28.84±2.57,临界游泳速度:1.45±0.25),2种裂腹鱼绝对、相对临界游泳速度均与体长呈正相关关系,短尾高原鳅与体长并无显著性关系(P>0.05);(2)3种实验鱼的突进游泳速度关系为:短尾高原鳅(体长:9.66±1.07,突进游泳速度:1.06±0.12)<齐口裂腹鱼(体长26.34±1.11,突进游泳速度:1.29±0.26)<重口裂腹鱼(体长:28.37±2.30,突进游泳速度:1.5±0.36),2种裂腹鱼绝对、相对突进游泳速度均与体长呈正相关关系,而短尾高原鳅与体长并无显著性关系(P>0.05)。(3)K-M曲线表明,90%目标鱼类的累计疲劳的临界和突进游泳速度分别为0.81、0.96m/s。当以短尾高原鳅、齐口裂腹鱼以及重口裂腹鱼为过鱼对象时,建议过鱼设施入口设计流速范围为0.81~0.96m/s,过鱼设施内部流速不应小于0.1m/s,休息区设计流速范围为0.1~0.81m/s。
英文摘要:
      In order to explore the swimming performance of fish in the Dadu River, Triplophysa brevicauda, Schizothorax prenanti and Schizothorax davidi were selected as the research objects in this study. The self-made Brett-type fish swimming performance test flume was used to measure the critical swimming speed and burst swimming speed of the three kinds of fish. The experimental results showed that : (1)The absolute critical swimming speed relationship of the three experimental fish was : T. breviflora ( body length : 9.92 ± 1.15, critical swimming speed : 0.91 ± 0.13 ) 0.05 ) < S.prenanti( body length : 22.01 ± 5.17, critical swimming speed : 1.09 ± 0.35 ) 0.05). (2) The absolute burst swimming speed relationship of the three experimental fish was : T. breviflora (body length : 9.66±1.07, burst swimming speed : 1.06±0.12 ) 0.05 ) < S.prenanti( body length : 26.34±1.11, burst swimming speed : 1.29±0.26 ) 0.05). (3) The K-M curve showed that the critical and burst swimming speeds of cumulative fatigue of 90 % target fish were 0.81 and 0.96 m/s respectively. When the fish passing objects are T. breviflora, S.prenanti and S.davidi, it is suggested that the designed flow velocity at the entrance of the fish passing facility should be 0.81~0.96 m/s, the flow velocity inside the fish passing facility should not be less than 0.1 m/s, and the designed flow velocity at the rest area should be 0.1~0.81 m/s.
