Abstract

Abstract: The serum biochemical and sex steroid hormone indices of Acipenser sinensis were measured in both marine and freshwater cultured female A. sinensis, in order to grasp the health level and gonadal development status of both marine and freshwater cultured A. sinensis. The results showed that（1）blood biochemical indicators: Urea, creatinine, uric acid, glucose, calcium and other indicators of the sea-farmed sturgeon were significantly higher than those of the freshwater farmed sturgeon （P<0.01）; Total protein, albumin and other indicators of the sea-farmed sturgeon were significantly lower than those of the freshwater farmed A. sinensis（P<0.05）; Globulin, triglyceride, high-density lipoproteins, low-density lipoproteins, and other indicators of the freshwater farmed A. sinensis were not significantly different from the freshwater farmed A. sinensis（P>0.05）;（2）Sex hormones: Estradiol, testosterone, yolk proteins and other indicators were significantly lower than the freshwater farmed A. sinensis（P<0.05）; 11-ketotestosterone, progesterone, and other indicators of sea-farmed and freshwater farmed A. sinensis were not significantly different（P>0.05）. It was found that the serum protein levels of freshwater farmed A. sinensis were higher, indicating that the freshwater farmed A. Sinensis’s own metabolism was more stable. The higher serum metabolism level and blood glucose level of the sea-farmed A. sinensis indicated that their body fluid metabolism level, energy and nutrient supply level were higher. The higher levels of sex steroid hormones in freshwater farmed sturgeon indicated that seawater farmed sturgeon need freshwater conditions to further stimulate gonadal development and enhance sex steroid hormone levels. The results of this study can provide a reference for the “land-sea-land” seawater relay conservation and species protection of A. sinensis.
