摘 要 ：在以玉筋鱼为饵料生物和最大摄食水平条件下 ,采用室内流水式实验 ,研究了黑鲷能量收支及温度对能量分配模式的影响。结果表明 ,黑鲷的摄食率、生长率、总代谢率和排泄率均随温度上升而呈减速增长趋势。不同温度条件下黑鲷的能量收支式为 :1 1 .2± 1 .98℃　 1 0 0 C=6.0 9F+9.38U+77.56R+7.0 2 G1 4 .7± 0 .4 5℃　 1 0 0 C=6.76F+8.75U+72 .77R+1 1 .82 G1 9.8± 0 .4 7℃　 1 0 0 C=2 .75F+8.94 U+73.52 R+1 4 .79G2 5.0± 0 .50℃　 1 0 0 C=1 .1 6F+9.1 8U+77.30 R+1 2 .81 G黑鲷的能量收支分配模式随温度而显著变化 ;其中能量代谢分配率和排泄分配率随温度升高呈 U形变化趋势 ,而生长能分配率则恰恰相反。不同温度下黑鲷的代谢能占了同化能的 83.2 5%～ 91 .70 % ,生长能仅占 8.30 %～ 1 6.75% ,可见黑鲷基本上属于低生长效率、高代谢消耗型鱼类。

Abstract:The energy budget of Sparus macrocephalus was determined by continous flow through test method in the laboratory under deferent temperature condition.Results showed that,within the range of experiment temperature,all of food consumption energy( C ),excretion energy( U ),total metabolism energy( R )and growth energy( G )tended to deceleration increment with temperature‘s rise.The energy assigning models was expressed with 4 budget formulas. The assigning models changed remarkably with temperat...
