摄食对南方鲇耗氧和氨氮排泄的影响
EFFECT OF FEEDlNG ON OXYGEN CONSUMPTION AND AMMONIA EXCRETION IN SILURUS MERIDIONALIS CHEN
-
摘要: 采用流水式呼吸仪,在水温27.0±0.5℃条件下同时测定了南方鲇(Silurus meridionalisChen)摄食前后的耗氧率和排氨率。实验结果表明:摄食前标准耗氧率和标准排氨率分别为116.4±6.4mgO2/kg/h和6.9±1.4mgNH4+/kg/h。摄食后耗氧率和排氨率均呈现迅速上升,到达最大值后再缓慢下降,然后恢复到静止水平的变化趋势:最大值分别为358.8±11.4mgO2/kg/h和76.1±2.5mgNH4+/kg/h;最大值出现时间分别为10.8±1.4h和10.1±0.9h;摄食后耗氧率和排氨率发生改变的持续时间分别为36.0±2.3h和37.2±2.8h;耗氧总增量和排氨总增量分别为88.3±2.7mgO2和23.1±1.7mgNH4+。实验结果显示,鱼类排氨率在摄食后的变化过程与其耗氧率的特殊动力作用(SDA)具有类似的特征,表明二者在能量代谢机制上相互关联;南方鲇的SDA总耗能的79.4%由蛋白质分解代谢所提供。Abstract: The postprandial rates of oxygen consumption and ammonia excretion in the southern catfish (Silurus meridionalis Chen)were measured by a continuous2flow respirometer at 27.0±0.5℃The results showed that the standard oxygen consumption rate and ammonia excretion rate were 116.4±6.4 mgO2/kg/h and 6.9 ± 1.4 mgNH4+/kg/h,respectively1The postprandial changing patterns inoxygen consumption and ammonia excretion were similar eachother. After the testedfish ate itsfood the both rates increased drastically,and reached their maximum levels(358.8 ± 11.4 mgO2/kg/h and 76.1±2.5 mgNH4+/kg/h) in a short time(10.8±1.4h and 10.1±0.9 h),then decreased slowly towards to their resting levels1The durationfor the postprandial changes were 36.0±2.3h and 37.2±2.8h;the increased magnitud of oxygen consumption and ammonia excretion were 88.3±2.7 mgO2and 23.1±1.7 mgNH4+ compared with the standards,respectively1This study suggests that response in the rate of ammonia excretion to post2feeding should be relative closely to that in the oxygen consumption1And 79.4 % of energy expenditure for the specific dynamic action(SDA)in postprandial metabolism might be due to protein catabolism in the catfish
