In this study, the plasma triglyceride and cholesterol contents of juvenile N. albiflora increased with the increasing dietary lipid level indicating a more active endogenous lipid transport, in response to the higher dietary lipid level ( Du et al., 2005 and Babin and Vernier, 1989), which is similar with previous study (Ding et al., 2010). Total plasma protein was a sensitive indicator of a dietary protein status (Pond et al., 1980). No significances were observed in plasma total protein contents among all treatments, the part of the reason maybe that all diets contained the same protein amounts in this study
