花鲈幼鱼个体代谢与体重关系的初步研究

Relation of Body Weight to Metabolism of Juvenile Japanese Sea Bass,Latelabra japonicus

实验室条件下测定花鲈 ( L ateolabrax japonicus C & V)的代谢率 ,温度为 ( 2 5.2± 0 .5)℃ ,鱼体湿重范围 :4 .64～ 52 .2 8g(平均体重 17.81g± 0 .33g)。饥饿鱼的正常代谢相关于体重的关系式 :Rr=15.37W0 .74 4。( r=0 .934 )。摄食代谢与摄食量呈线性正相关关系 ,摄食代谢水平为正常代谢的 1.8～ 2 .4倍。

The routine metabolic rate of the sea perch, Lateolabras japonicus C & V, was estimated in the laboratory at temperature (25.2±0.5)℃; the live weight of the fish is 4.64~52.85g. The routine metabolic rate of starved fish ( Rr ) was related to fresh body weight by the equation R r=15.37W 0.744 (r =0.934). The feeding metabolic rate increased linearly with increased food consumption.
