摘要
以真鲷 (起始体重 :1 1 .5～ 1 4.8g)为实验对象 ,在平均水温 2 4.5 7℃下 ,进行饱食状态下的真鲷幼鱼摄食 -生长实验 ,饵料为玉筋鱼 ;对其摄食量、生长及粪便进行直接测定 ,对能量收支、氮和碳收支各组份进行估计和计算。结果表明 ,真鲷幼鱼的能量分配对策是 ,需较多的能量维持其代谢需求 ,同时 ,有较多的氮和碳随代谢产物排出体外 ,从而导致较低的能量生长及物质生长。
The feeding growth experiments of red sea bream, Pagrosomus major, were carried out at satiation and 24.57 ℃ of average water temperature. Each component of energy budget, nitrogen and carbon budget in red sea bream was measured and calculated. As percentage to food consumption, the metabolisms in energy budget and carbon budget were highest, and excretory nitrogen was also highest in nitrogen budget. It was concluded that it required more energy, carbon and nitrogen to balance metabolism, otherwise it result in less growth in energy and matter.
