摘　　要：研究了黑鲷(Sparus macrocephalus)耗氧率的昼夜变化规律及其与体重、水温的关系,结果表明,黑鲷耗氧率随水温的升高而升高,随个体的增大而降低;23:00耗氧率最高,为3.16±0.26μg·(g·min)-1,07:00左右耗氧率最低,为0.74±0.59μg·(g·min)-1。黑鲷白天的平均耗氧率为1.98±0.84μg·(g·min)-1,夜间的平均耗氧率为1.96±0.63μg·(g·min)-1,其代谢水平的昼夜变化不明显(n=10,t=0.034<t0.05)。The diurnal rhythm of oxygen consumption and effects of body weight and temperature on oxygen consumption rate of Sparus macrocephalus were examined under a flowlng-water apparatus. The results revealed that the oxygen consumption rate of S. macrocephalus exhibits an increase with the rise of water temperature but a decrease with the increment of body weight. The rate of oxygen consumption varied with the alternation of day and night. The highest oxygen consumption rate was 3. 16 ±0. 26 μg.（g·min）^ -1 at 11：00pm, and the lowest oxygen consumption rate 0. 74 ±0. 59 μg·（g·min）^ -1 at 7：00am. The mean oxygen consumption rate was 1.98 ± 0. 84 μg· （g·min）^ 1- at day and 1.96 ± 0. 63 μg· （g·min）^ -1 at night. The results showed that the change of metabolism level of S. macrocephalus is not significantly between day and night （n = 10, t = 0. 034 〈 t0.05 ）.
