| 中文摘要: |
| 摄食和运动不仅是动物最主要的生理活动,同时也是机体代谢能量消耗的主要过程。相关研究表明鱼类摄食代谢主要由营养物质同化过程的耗能组成,其食物蛋白质同化耗能远低于陆生脊椎动物,而摄入营养物质不平衡可能导致摄食代谢耗能增加;鱼类摄食代谢和运动代谢上可能存在能量消耗与性能维持之间的权衡,且都可能受最大代谢能力限制。鱼类不仅在摄食和运动代谢的相对大小及其他特征上存在差异,而且在摄食和运动代谢竞争上存在不同的模式。从功率分配的角度,研究鱼类摄食和运动代谢特征及其与物种生态习性的关系将成为鱼类能量学研究的重要方向之一。 |
| 英文摘要: |
| Feeding and locomotion are not only the primary physiological activities but also the main energy consumption processes in fishes.Studies related to feeding metabolism have demonstrated that the main energy expenditure in feeding is caused by assimilatory process of dietary nutrients.The energy expenditure of protein assimilation is much lower than that in terraneous vertebrate.Imbalance of dietary nutrients will increase the energy expenditure during the process of assimilation; there is trade-off between energy expending in activity of feeding and locomotion vs.maintenance in fish.The trade-off is limited by the maximum potential metabolism ability.Inter-specific differences are found in feeding and locomotion metabolism,other characteristic,as well as in competition mode.The investigation on the relationship between metabolism characteristic of feeding and locomotion with the ecological habits of fish can be taken as one important research topic in fish energetics in the further studies. |
