摘　　要：在平均水温25℃条件下,测得平均体重10.0 g的瓦氏黄颡鱼(Pelteobagrus vachelli)及平均体重12.6g的黄颡鱼(P.fulvidraco)耗氧率分别为0.21和0.23 mg/g.h,窒息点分别为0.91和0.75 mg/L;平均体重75.8 g的瓦氏黄颡鱼及平均体重85.4 g的黄颡鱼耗氧率分别为0.16和0.12 mg/g.h,窒息点分别为0.77和0.54 mg/L。分析表明,瓦氏黄颡鱼的耗氧率和窒息点都高于黄颡鱼。The results obtained from experiments under 25℃ of water temperture show that based on Peltobagrus vachelli and P.fulvidraco （average body weights are 10.0 g and 12.6 g respectively）, oxygen consumption rates are 0.21 mg/g·h and 0.23 mg/g·h, suffocation concentrations are 0.91 mg/L and 0.75 mg/L, respectively. In case of mean body weight of 75.8 g and 85.4 g, oxygen consumption rates of P. vacheUi and P. fulvidraco are 0.16 mg/g·h. and 0.12 mg/g·h, suffocation concentration are 0.77mg/L and 0.54 mg/L, respectively. Analysis shows that the oxygen consumption rate and suffocation concentration of P. vacheUi are higher than those of P .fulvidraco.
