| Abstract: | The effects of body weight and temperature on the carbon budget of the juvenile bastard halibut,Paralichthys olivaceus, were studied at temperature 13.5, 18, 21.5 and 24 °C, respectively. The carbon intake, faecal and growth carbon were measured, and the carbon respiration was calculated using the carbon budget equation (C c=Gc+Fc+Rc). The combined relationship between different components of the carbon budget, body weight and temperature could be described by regression equations:C c=1.0206W 0.8126e0.1483T;G c=0.0042W 1.4096(?5.11T 3+285.90T 2?5173.72T+30314.03);F c=0.0485W 0.77t1 e0.1624T ;U c=1.4333W 0.6715 e0.1487T . Body weight had no significant effect on the carbon absorption efficiency and the conversion efficiency. |
