摘要/Abstract

摘要： 研究了豹纹鳃棘鲈幼鱼由盐度为30向低盐(盐度为25、20、15）及向高盐(盐度为35)突变过程中其耗氧率、排氨率、代谢率、排泄率等的变化。结果表明: 盐度改变后,豹纹鳃棘鲈幼鱼的耗氧率和排氨率均呈现升高趋势,突变组较对照组差异显著（P<0.05）,随着盐度突变范围的增大,变化趋势更为明显。O:N比无论向低盐度或高盐度突变均降低。在各突变盐度水平下,豹纹鳃棘鲈基础代谢消耗的底物以蛋白质和脂肪为主,糖类为辅。

关键词: 豹纹鳃棘鲈, 盐度, 耗氧率, 排氨率

Abstract: The changes of the oxygen consumption rate, ammonia excretion rate, metabolic rate and excretion rate of juvenile Plectropomus leopardus lacépède were determined when the salinity changed abruptly from 30 to lower levels (25, 20, 15 salinity) and to a higher level (35 salinity). The results show that the oxygen consumption rate, ammonia excretion rate of juvenile Plectropomus leopardus lacépède displayed an increasing trend, and the significant difference was found between the salinity changed group and the control group (P<0.05), and with the increase range of salinity changed, the trend was even more obvious. The ratio of O:N all decreased whether the salinity changed to the lower salinity or higher salinity. The main materials involved in the basal metabolism of Plectropomus leopardus lacépède were protein and lipid, and then carbohydrate.

Key words: Plectropomus leopardus lacépède;, salinity, oxygen consumption rate, ammonia excretion rate
