摘要(Abstract)：

水温28±1℃条件下,投喂人工配合饲料,研究摄食水平1%、2%、3%、4%、5%(每日投喂量占初始实验鱼湿重的质量百分比)及饱食对卵形鲳鲹幼鱼(初始体重5.77±0.45g)生长及能量收支的影响。结果表明,卵形鲳鲹幼鱼特定生长率、转化效率、摄食率随着摄食水平的提高而增长,摄食水平达4%时干重特定生长率与饱食组差异无显著性(P>0.05),摄食水平达5%时,湿重、蛋白质和能量生长率与饱食组差异无显著性(P>0.05);摄食水平达4%时能值转化效率与饱食组差异无显著性(P>0.05),摄食水平达5%时,干重、蛋白质转化效率与饱食组差异无显著性(P>0.05);摄食水平达2%时干重、蛋白质表观效率与饱食组差异无显著性(P>0.05),摄食水平达4%时,能量表观效率与饱食组差异无显著性(P>0.05)。生长能分配率随摄食水平升高而显著增加(P<0.05),代谢能、排粪能及排泄能分配率的变化则相反。建立了6种摄食水平条件下卵形鲳鲹幼鱼的能量收支方程。
