| 摘 要： | 在平均水温27．0℃条件下，测得平均全长11．1cm、平均体重12．0g的巴沙鱼幼鱼的耗氧量为3．8926mg／（尾·h），耗氧率为0．3237mg／（g·h），窒息点为0．5297mg／L。巴沙鱼昼间耗氧率明显高于夜间耗氧率，其对低氧的耐受力较强。

| Abstract: | The results obtained from experiments at 27.0 ℃ of average water temperature show that juvenile Basa , Pangzsius bocourti （ average total length and body weight are 11.1 cm and 12.0 g ） had oxygen consumption capacity of 3.8926 mg/（ind·h） , oxygen consumption rate of 0.3237 mg/（ind·h）, suffocation concentration of 0.5297 mg/L . The oxygen consumption rate of basa in the daytime was obviously higher than it at night. Basa had strong resistance to low oxygen level. |
