Relation of body weight and food consumption to metabolic rate of juvenile Japanese sea bass,Lateolabrax japonicus

The metabolic rate of Japanese sea bass,Lateolabrax japonicus (C & V), was estimated in laboratory at temperature 25.2±0.5°C. The fresh weight of the fish was 4.64–52.28 g (average of 17.81±0.33 g). The routine metabolism was related to body weight by the exponential equation:R _r =14.966W ^0.74 (r=0.934). The rate of feeding metabolism increased linearly with food consumption. Feeding metabolic rate was 1.8–2.4 times the routine metabolic rate. Contribution No. 4021 from the Institute of Oceanology, Chinese Academy of Sciences
