摘要： In recent years, the number of Chinese sturgeon (Acipenser sinensis) has decreased, due to food shortage and starvation as a result of human activity. In this study, the effects of starvation on the metabolism of juvenile sturgeon were examined by measuring their blood parameters over time to assess the utilization of energy resource and identify biomarkers of stressed sturgeon populations. Plasma was sampled every six days during 49 days of starvation. The results showed that the total protein concentration of sturgeon increased slightly during the initial period of the experiment, and then declined significantly after 25 days. It has become apparent that the concentration of albumin (ALB) declined significantly after 31 days of starvation. Glucose (GLU) concentration was decreased significantly after only 7 days of starvation, and dripped significantly again after 31 days. Triglyceride (TGL) and cholesterol (CHOL) levels were steady, until as late as 25 days after starvation. Other parameters including urea, alanine aminotransferase, aspartate aminotransferase, and lactate dehydrogenase also reduced significantly. In contrast, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and alkaline phosphatase were less affected. The activity of alanine aminotransferase (ALT) decreased significantly after 13 and 37 days of starvation. The activity of lysozyme (LSZ) increased generally and there were significant difference between 43-day starvation group and 4 starvation groups of 1-19 days. Therefore, these results indicate that carbohydrates were metabolized preferentially in the blood of juvenile Chinese sturgeon, then proteins, and finally lipids. Furthermore, GLU, ALB, CHOL, and TGL can be used as indicators to nutritional condition. Obvious effects occurred in the blood of juvenile Chinese sturgeon after 13 days of starvation.
