以玉筋鱼和鹰爪糙对虾为生物饵料 ,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能量收支各组分和能量收支模式的影响。结果表明 ,黑的生长量、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。黑的能量收支模型随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 ,摄食不同饵料对黑的能量收支模型的影响也十分显著。
The effects of feeding level and dietary species on the energy budget and expenditure of black pomfret (Brachiaria crassipes) were studied using indoor flow simulation experiment. The results showed that the growth, total metabolic rate, total excretion and excretion and ecological conversion efficiency increased with the increase of feeding level. The quantitative relationship between them could be quantitatively described by logarithmic curve or straight line respectively. Feed can cause significant differences in feeding, growth, excretion and total metabolism of black currant, but can not change the ecological conversion efficiency in specific energy units. The energy budget model of black pomfret has more obvious differences with different feeding levels. The metabolic rate and excretion rate of distribution vary with U-shape when the feeding level increases, while the rate of growth and energy allocation is just the opposite. In addition, feeding different bait on the energy budget of black currant model is also very significant impact.
