| 摘 要： | 以玉筋鱼和鹰抓糙对虾为生物饵料，采用室内流水模拟实验法研究了摄食水平和饵料种类对黑Jun能量收支各组分和能量收支模式的影响。结果表明，黑Jun的生长量、总代谢量、排泄量及生态转换效率均随摄食水平升高呈增长趋势，二者之间的定量关系可分别用对数曲线或直线加以定量描述；不同生物饵料能造成黑Jun摄食、生长，排泄和总代谢水平的显著差异，但却不能改变以比能值为单位的生态转换效率。黑Jun的能量收支模型摄食水平不同有较明显差异，代谢能分配率和排泄能分配率随摄食水平增大呈U型变化趋势，而生长能分配率却恰恰相反。另外，摄食不同饵料对黑Jun的能量收支模型的影响也十分显著。

| Abstract: | The energy budget of Black snapper (Sabastodes fuscescens) was determined by continuous flow simulating method in laboratory under different feeding level and food species conditions. Results showed that all of excretion energy (U), total metabolism energy (R) and growth energy (G) tended to increase with ration level's rise. There was remarkable difference about each energy budget constituent with different food fed, but not change about ecological conversion efficiency. The energy budget models changed with different feeding level remarkably. In the models, assigning rates of metabolism and excretion energy changed like U shape with ration level's rise, but that of growth energy turned out contrary to it. There were remarkable differences between the models obtained from different food fed. |
