Abstract: Effects of clove oil on oxygen consumption rate and blood biochemistry were studied in Siberian sturgeon Acipenser baerii.Oxygen consumption rate（OCR） of the sturgeon exposed to 2-30 mg/L clove oil was increased first and then decreased.There were significantly higher OCR＇s in the sturgeon exposed to 2 mg/L and 4 mg/L clove oil than that in the control group,without significant difference between 6 mg/L group and control group.OCR was found to be significantly lower in the sturgeon in 8-30 mg/L groups than that in the control group.There were no significant differences in concentrations of P3＋,total protein,total cholesterol,glucose,urea,alanine aminotransferase,and alkaline phosphatase in the juveniles exposed to 60-180 mg/L clove oil for ten minutes.There were significantly higher concentrations of high density lipoprotein cholesterol,low density lipoprotein cholesterol and triglycerides in the anesthetic groups than those in the control group while there were significantly lower total bilirubin concentration than that in the control group.The concentrations of Mg2＋ in 90-180 mg/L groups and aspartate aminotransferase in 120-180 mg/L groups were higher than that in the control group,respectively.The concentrations of albumin and lactate dehydrogenase were fluctuated among experimental groups.Overall,clove oil is used in the short distance transportation at a dose of 8-30 mg/L,and has less effect on the blood biochemistry of Siberian sturgeon at a dose of 60-90 mg/L.
