| 英文摘要 | Growth, faecal production, nitrogenous excretion and energy budget of juvenile yellow grouper (initial body weight 5.5 g or so) at various ration levels (starvation, 0.5%, 1% and 2% of initial body weight per day, and satiation) were investigated in this study. Faecal production (f, mg g(-1) d(-1)) and nitrogenous excretion (u, mg g(-1) d(-1)) increased markedly with increased ration level (RL, % per day), described as f-0.483RL+0.112 for faecal production and u=0.218RL+0.219 for nitrogenous excretion, respectively. Feed absorption efficiency (FAE, %) increased as ration increased with ranges of 91.4-94.0%, 95.6-97.3% and 96.5-97.6% for FAE(d), FAE(p) and FAE(c), respectively, but all of the variations were small. Relationships between specific growth rate in wet weight (SGR(w), % per day), dry weight (SGR(d), % per day), protein (SGR(p), % per day), energy (SGR(e), % per day) and ration level (RL, % per day) were linear and described as simple equations SGR(w)=0.738RL-0.764, SGR(d)=0.871RL-0.928, SGR(p)=0.904RL-0.966 and SGR(c) = 1.03 8RL-1.060. Feed conversion efficiency in wet weight (FCEw %), dry weight (FCEd, %), protein (FCEp, %) and energy (FCE,, %) all increased as ration increased and maximized at ad libitum ration level. Energy budgets of juvenile Epinephelits awoara at satiation ration level was: 100C=2F+4U+75R+19G or 100A=80R+20G, where C is food energy, A is assimilated energy, F is faeces energy, U is excretion energy, R is metabolism energy and G is growth energy.
