摘　　要：实验测定了咸海卡拉白鱼的耗氧率和窒息点,并做出了耗氧率的昼夜变化曲线。结果表明,在水温16～30℃条件下,卡拉白鱼的耗氧率和窒息点随温度的升高而增加;耗氧率与温度的线性回归方程为R=0.028T-0.312(R=0.845),不同体重鱼(3.97～132.22g)在24℃时,耗氧率和窒息点随体重的增加而降低,耗氧率与体重的关系为R=0.6548W-0.21(R=0.974)。卡拉白鱼的昼夜耗氧昼夜平均耗氧为0.3137mg/g.L,耗氧最低值出现在日间11:00时,耗氧最高值出现在凌晨6:00时。The method of respiratory chamber has been applied to study oxygen consumption rate and asphyxiation point of Chalcalburnus chalcoides aralenesis, and the diurnal variation curves of oxygen consumption. The results demonstrated that under the controlled temperature 16 -30℃, the oxygen consumption rate and asphyxiation point increase as temperature rose , and decrease as body weight increased. The linear regression relationships of oxygen consumption rate and temperature can be described as R = 0.028T - 0.312 （ R = 0. 845 ） , the relationship between oxygen consumption and body weight is R =0.6548W^-0.21（ R =0.974）. The average oxygen consumption rate is 0.3137mg/g. LThe lowest oxygen consumption rate appears at 11：00 and the highest at 6： 00.
