对美国大口胭脂鱼的耗氧率、耗氧量及窒息点进行了测定。①耗氧率：平均体长6．9cm，体重6．7克的美国大口胭脂鱼的耗氧率为0．1641mg／g.hr，耗氧量1．115mg／尾．hr；平均体长7．0cm，平均体重6：87克的美国大口胭脂鱼耗氧率0．1433ndg／ghr，耗氧量0.1324mg／尾hr；平均体长10cm，体重24．05克的美国大口胭脂鱼耗氧率随体重增加而减小，而耗氧量随鱼体体重增加而增大。大口胭脂鱼的耗氧量呈现出明显的昼夜变化规律。②窒息点：美国大口胭脂鱼（6．9－10cm）的窒息点在水温30．6－32．1℃时为0．3000－0．3500mg／L。
Oxygen consumption rate, oxygen consumption and suffocation point of the American bigmouth are measured. Oxygen consumption rate: The average body length of 6.9cm, body weight 6.7 grams of the United States Ostulae Oxygen consumption was 0.1641mg / g.hr, oxygen consumption 1.115mg / tail. hr; the average body length of 7.0cm, the average body weight of 6:87 grams of the American bigmouth carp oxygen consumption rate of 0.1433ndg / ghr, oxygen consumption 0.1324mg / tail hr; average body length 10cm, weight 24.05 grams of the United States big mouth The oxygen consumption rate of bream fish decreases with body weight gain, while the oxygen consumption increases with body weight gain. Oral diurnal oxygen consumption showed a significant diurnal variation. ② suffocation point: the United States bigmouth carmine (6.9-10cm) suffocation point at water temperature 30.6-32.1 ℃ 0.3000-0.3500mg / L.
