| 摘 要： | 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。

| Abstract: | Growth and energy budget were observed on Trachinotus ovatus juveniles (initial body weight 5.77 ± 0.45 g) at six ration levels (1%,2%,3%,4%,and 5% of initial body weight per day and ad libitum) kept at 28 ± 1 ℃ and fed formula diet.The results showed that specific growth rate in wet weight,dry weight,protein weight and energy weight increased significantly with ration levels.A curves relationship existed between ration size and specific growth rate.Conversion efficiency in dry weight,protein weight and energy weight increased significantly with ration levels.There was a significant difference for conversion efficiency between different levels.Apparent digestibility in dry weight,protein weight and energy weight increased with ration levels,but apparent digestibility in energy weight increased significantly.With the increase of ration level,the energy budget models changed remarkably,G/C increased significantly as ration levels increased,but R/C on the contrary.Energy budgets of Trachinotus ovatus juveniles at satiation ration were 100.00 C=48.94 G + 4.97 F + 6.15U + 39.94R,where C,G,F,U and R represent food consumption,growth,faecal production,nitrogen excretion and metabolism,respectively. |
