Abstract Eighteen serum indices including protein ,fat ,glucose ,and inorganic ion levels and enzyme activity were monitored in 3 years old ,8~10 years old ,14~16 years old farmed F1 Chinese sturgeon (Acipenser sinensis) and the Chinese sturgeon with Ⅰ ,Ⅱ and Ⅲ stage gonads domesticated in artificial freshwater environment by automatic biochemical analyzer (type:7170A of Hitachi) to study the biological characteristics of Chinese sturgeon .The results showed that the levels of serum protein including total protein (TP) ,albumin(ALB) ,globulin (GLOB) and Na+ wereshown to be ascendant trend .The levels of serum fat including total cholesterol (CHOL) ,triglyceride (TRIG) ,high density lipoprotein cholesterol (HDLC) and low density lipoprotein cholesterol (LDLC ) were found to be decreased firstly ,and then increased as the time was elapsed while the concentration of serum glucose (GLU) was raised first and then decreased . The maximal activities of serum enzymes including glutamine-oxaloacetate (AST ) , creatine kinase (CK ) , glutamate-pyruvate transaminase (GPT ) , lactate dehydrogenase (LDH ) and alkaline phosphatase (ALP) were observed in the 3 year old individuals of F1 Chinese sturgeon .There were significantly lower 9 blood indices(Cl- ,CK ,ALP ,TP ,ALB ,GLOB ,CHOL ,HDLC and LDLC)in the wild Chinese sturgeon than in 14 ~ 16 years old group of farmed F1 Chinese sturgeon with same developmental gonads (P<0 .05) ,even though the wild Chinese sturgeon showed stage Ⅲ gonads .No significant differences in the other blood indices were found in the wild and farmed Chinese sturgeon (P>0 .05 ) . T he findings indicate that the significant differences in blood biochemistry characteristics are involved in the inherent background variability of these sturgeon individuals ,including exposure history in different habitats ,different developmental gonad and physiological characteristics .
