中文摘要：

在水温25℃时,采用封闭静水式和封闭流水式装置测定了大弹涂鱼的窒息点及其昼夜代谢规律。结果表明,大弹涂鱼的窒息点为0.71mg/L;其标准代谢（SM）和常规代谢（RM）随体质量的增加而降低,不同规格处理组昼夜变化规律相同,即夜间代谢强于白天,但不同处理组SM（F=35.247,P〈0.01）和RM（F=4.679,P〈0.01）差异均极显著;S组、M组和L组特殊动力代谢（SDA）的耗氧率峰值分别为0.85、0.65和0.44mg/（g·h）,分别为其SM的1.18、1.43和1.21倍,持续时间均为14h;S、M和L组排氨率的峰值分别为12.00、20.20和24.98μmol/（g·h）,分别为其饥饿状态下排氨率的1.33、1.68和5.20倍。

英文摘要：

The oxygen consumption rate on the asphyxiant point of Boleophthalmus pectinirostris were studied. The results demonstrated that, In the temperature of 25℃, the fish had a mean asphyxiation point of 0.71mg/L. The standard metabolism （SM） and routine metabolism （RM） ofB. pectinirostris decreased significantly with increasing body mass, and changed with the same pattern in the 3 groups, i.e., being higher at night than in day time. There was a significant difference in the SM （F=35.247, P〈0.01） and RM （F=4.679, P〈0.01） among the 3 groups. The peak values of the specific dynamic metabolism of groups S, M, and L were 0.85, 0.65 and 0.44mg/（g.h）, being 1.18, 1.43, and 1.21 times higher than their SM, respectively, and maintained about 14h. The ammonia excretion rates of groups S, M, and L reached the peak with the peak values being 12.00, 20.20 and 24.98μmol/（g.h）, and 1.33, 1.68 and 5.20 times higher than those in starvation state, respectively.
