中文摘要:
      测定了5个不同盐度(0、10、20、25、28)下分别养殖20d的施氏鲟(Amursturgeon,Acipenser schrenckii)的血液生化指标。结果表明:总蛋白(TP)含量随盐度的升高先上升后下降,总胆红素(T—BIL)随盐度的升高逐渐增加,甘油三脂(TRIG)的变化趋势与总蛋白TP基本一致,总胆固醇(CHO—L)随盐度的升高变化不明显,高密度脂蛋白(HDL—C)随盐度的升高先缓慢下降后略有上升。血糖(G)随盐度的升高先缓慢下降后逐渐上升。肌酐(CREA)的含量随盐度的升高先上升后下降,尿素氮(BUN)随盐度的升高先上升后下降。随盐度的升高,碱性磷酸酶(ALP)逐渐下降,血清淀粉酶(AMY)先下降后上升,谷草转氨酶(AST)和谷丙转氨酶(ALT)先上升后下降再上升。Na^+浓度先上升后下降最后基本保持稳定,Cl^-浓度、P含量和Na^+浓度变化趋势基本一致,K^+浓度先上升后下降,Ca^2+浓度则无显著性变化。从驯化后血液生化指标分析,施氏鲟具有较强的渗透调节能力,经过驯化可以在盐度28的海水中生活。
英文摘要:
      Haematological biochemistry indices of Acipenser schrenckii cultured at different salinities(0,10,20,25,28) for 20 days respectively were measured.The results showed that the values of total protein(TP) increased first and then declined with the growth of the salinities.The values of T-BIL increased gradually with the addition of the salinities.The varieties of TRIG was consistent with that of the TP,the values of cholesterin(CHOL) had no significant variations with the increase of the salinities,and high density lipoprotein cholesterin(HDL-C) first decreased slowly then increased slightly with the enhancement of the salinities,and the values of blood glucose(G) first reduced then increased with the growth of the salinities.The values of CREA increased first and then declined,The values of BUN increased first and then declined.With the growth of the salinities,the values of alkaline phosphatase(ALP) declined gradually,and the values of amylase(AMY) first dropped then rose,and the values of aspartate aminotransferase(AST) first increased,then dropped and added in the end,which was similar to the varieties of the alanine aminotransferase(ALT).Na+ concentration first increased,then declined and kept stable finally,which was similar to the changes of Cl-and P,and K+ concentration first increased and then decreased,yet Ca2+ concentration had no significant changes.By analysing the haematological biochemistry indices after salinities domestication,Amur sturgeon possessed better osmoregulation abilities and could live in the 28 salt water after domestication.
