摘　　要：本试验采用鱼类生物能量学的方法，对花鲈个体水平上的能量转换进行了研究。提出了不同温度、不同盐度条件下花鲈能量收支的实验方程。结果表明：盐度对大规格花鲈鱼种能量收支各组分的影响大于温度；花鲈夏花鱼种和大规格鱼种分别在盐度5和10时能获得最佳能量分配模式；温度对大规格花鲈鱼种的能量收支各组分的分配比例影响不大，在水温15℃～30℃范围内，其平均能量收支式为：100C＝1．773F＋1．135U＋40．317G＋56．775R总；不同规格的花鲈其能量分配模式有明显的不同，鱼种规格越小，其代谢能占的比例越高，生长能的比例越低。By the method of fish-bioenergetics, the energy conversion of Laterolabrax japonicus in individual level was studied, and the experimental equation of energy budget for L.japonicus assimilated and conversed in differrent temperature and salinity was suggested.The experimental results showed that: The effect of salinity to composition of energy budget of L. japonicus's large-size larvae was greater than that of temperature. Summer fry and large-size larvae of L. japonicus can get best pattern of energy distribution in the salinity of 5‰ and 10‰ respectively. The effect of temperature to every composition of energy budget of L. japonicus's large-size larvae was not obviously, in the temperature range 15℃-30℃,and the mean equation of energy budget was 100C =1. 773F+1. 135U + 40. 317G +56. 775R_(total). There is obvious different of energy distribution pattern of differrent sized L.japonicus, the smaller of the fish, the greater of the proportion of its metabolic energy, and the smaller of the proportion of its growth energy.
