中文摘要：

研究了不同摄食水平（从饥饿至饱食）和温度（21℃、27℃和33℃）对军曹鱼幼鱼（平均初始体重约10g）生长和氮收支的影响，并建立了生长-摄食/温度关系和不同摄食水平和温度条件下的氮收支方程。结果表明，在实验的温度范围内，军曹鱼幼鱼特定生长率均随摄食水平的增加呈显著增长趋势，生长-摄食关系在33℃时表现为线性相关，在27℃和21℃时表现为减速增长趋势，采用对数函数定量描述；在实验的摄食范围内（饥饿组除外），军曹鱼特定生长率随温度增加呈增长或先升后降的变化趋势，两者间的关系均采用二次函数定量描述。在实验的温度范围内，随摄食水平增加，军曹鱼幼鱼食物转化效率在水温33℃和21℃时呈增长趋势，在水温27℃时呈先升后降的变化趋势；在实验的摄食范围内（饥饿组除外），军曹鱼幼鱼食物转化效率随温度增加呈增长或先升后降的变化趋势，饱食时虽然食物转化效率最大值出现在33℃时，但方差分析显示33℃和27℃之间无显著性差异，其他摄食水平组在27℃时有最大值。在实验的摄食水平和温度范围内，军曹鱼幼鱼的排泄氮随摄食水平和温度的增加均呈显著增长趋势。

英文摘要：

Effects of ration （from starvation to satiation） and temperature （21℃, 27℃ and 31℃） on growth and nitrogen budget of young cobia （initial body weight about 10g） were studied, and the relationship between specific growth rate （SGR） and ration as well as temperature and the nitrogen budget were established in this paper. The results showed that at a given temperature, as ration increased, SGR increased significantly, exhibiting a linear pattern described as a simple function at 33℃whereas a decelerating pattern described as a logarithmical equations at 27℃and 21℃. At a given ration, except for starvation, as temperature increased, SGR increased or first increased then decreased, all described as quadric functions. At a given temperature, as ration increased, feed conversion efficiency （FCE） increased at 21℃ and 33℃ whereas first increased then decreased at 27℃. At a given ration （except for the starvation）, as temperature increased, FCE increased or first increased then decreased and peaked at 27℃ for fish fed restricted food while there was no significant difference between 27℃ and 33℃though FCE peaked at 33℃ for fish fed satiation. Over the experimental ration and temperature range excretion nitrogen of young cobia increased significantly with increasing ration and temperature.
