| 摘 要： | 在封闭式流动水体中,对昆明裂腹鱼鱼苗的耗氧率和临界窒息点进行初步测定。试验结果表明:在常温(20℃)条件下,临界窒息点为0.8mg/L(L:12.5cm-16.4cm,W:15.32g-34.28g)。而耗氧率的测定结果则为:在常温20℃:昼夜平均耗氧率为0.215mg/g.h(L:13.5-15.5cm,W:19.75-31.31g),昼夜耗氧率差异不明显;在17.5℃时,昼夜平均耗氧率为0.13 mg/g.h(L:11.9-15.1cm,W:15.16-27.74g),昼夜耗氧率差异明显;在15℃时,昼夜平均耗氧率为0.10 mg/g.h(L:12.6-14.5cm,W:15.66-25.35g),昼夜耗氧率差异明显,昆明裂腹鱼的耗氧率随温度的降低而减小。 |

| Abstract: | Shizothorax grahami fry’s oxygen consumption rate and critical asphyxiation point were determined in a closed flowing water system.Under normal temperature(20 °C),the critical asphyxiation point is 0.8 mg/L(L: 12.5 cm-16.4 cm,W: 15.32 g-34.28 g).The oxygen consumption rates at different temperatures were: at 20 °C: the daily average oxygen consumption rate was 0.215 mg/g.h(L: 13.5 cm-15.5 cm,W: 19.75 g-31.31 g),No significant difference in instantaneous oxygen consumption rates was observed between day and night;at 17.5 °C,0.13 mg / g.h(L: 11.9 cm-15.1 cm,W: 15.16 g-27.74 g),significant difference in instantaneous oxygen consumption rates was observed between day and night;at 15 °C,0.10 mg/ g.h(L: 12.6 cm-14.5 cm,W: 15.66 g-25.35 g),significant difference in instantaneous oxygen consumption rates was observed between day and night.the daily average oxygen consumption rate decreases with the decreasing temperature. |
