以中国地质公园(神农架)野生动物繁育基地提供的齐口裂腹鱼(Schizothorax prenanti)幼鱼(体长为14.0-17.5 cm,体重为39.6-65.6 g)为研究对象,利用自制鱼类游泳特性(Swimming performance)研究装置,运用递增流速法(Stepped velocity test),研究了鱼类疲劳后20d和40d的游泳特性恢复状况。结果表明：(1)在20d内齐口裂腹鱼临界游泳速度(Critical swimming speed, Ucrit)相比于初次测试(20d前)有所降低,20d内的恢复状况较差；而在40d后,临界游泳速度已经基本恢复到最初状况,40d内的恢复状况较好。(2)疲劳后鱼类游泳效率显著下降,并且在40d后无法恢复正常。虽然40d后速度指数低于20d后速度指数,40d后游泳效率高于20d后游泳效率,但是相对于初次测试,40d后游泳效率恢复效果并不明显。(3)齐口裂腹鱼在疲劳后40d 内,恢复能力(Recovery capability)无法恢复到正常状况,但由于3次测试中疲劳后过量耗氧(Excess post-exercise oxygen cost, EPOC)波动并不大,说明疲劳对其恢复能力影响并不大。(4)20d后和40d后无氧呼吸时间均较第一次测试时提前,说明疲劳损伤对其有氧呼吸能力产生了持续影响。(5)疲劳对鱼类生态行为(Ecological behavior)影响不明显。研究有利于为鱼道建设提供基础资料,对生物多样性保护具有深远意义。

The recovery of swimming performance of Schizothorax prenanti (Body length:14.0-17.5 cm, body mass:39.6-65.6 g) which were provided by a wild animal breeding base in the National Geopark in Shennongjia, China, were studied by a stepped velocity test in swimming performance equipment (an intermittent-flow respirometer). The fish were examined 20 days and 40 days after juvenile Schizothorax prenanti swam and became fatigued. Results indi-cated:(1) The critical swimming speed (Ucrit) of Schizothorax prenanti in 20 days was lower than speed at the beginning, which indicate that the recovery of swimming performance was worse 20 days later. However, the critical swimming speed was improved 40 days later, appearing similar to the beginning, which indicated that the recovery situation was better 40 days later. (2) Swimming efficiency decreased after the fish became fatigued, and was unable to return to normal 40 days later. The speed exponent of 40 days later was lower than 20 days, and swimming efficiency of 40 days later was higher than 20 days, however, the recovery of swimming efficiency still was worse 40 days later. (3) The re-covery capability of swimming performance did not return to normal situation 40 days later, but excess post-exercise oxygen cost (EPOC) was not unstable, therefore fatigue has little effect on the recovery capability. (4) The anaerobic of 20 days and 40 days occurred both earlier than the first tested time, which illustrated that fatigue has a sustained effect on aerobic capability. (5) Fatigue has no obvious effect on ecological behavior. This study will provide basic informa-tion for building fishways and be great meaningful for biodiversity conservation on depth.
