The energy loss through feces was 0.077C (C: food consumption, KJ/d) and the energy loss through excretion was 0.052C at maximum feeding rate. In that the ratios of F and U to C were low in fish energy budget equation (Cui et al., 1997), the energy loss through feces at optimum feeding rate could be estimated by 0.077C〓(C〓: the optimum feeding rate) and the energy loss through excretion at optimum feeding rate could be estimated by 0.052C〓. The relationship between total energy content for immature gibel carp and body weight was lnE=1. 476+1. 127lnW.
