摘要: 研究了在低温(13℃)下饥饿胁迫对9月龄大黄鱼血清生化指标的影响。将400尾大黄鱼随机分成两组,一组为实验组,不投喂饲料;另一组为对照组,定时投喂饲料。实验开始30 d后,测定大黄鱼11种血清生化指标。结果显示,实验组大黄鱼血清的尿酸(UA)、尿素(UREA)、总胆固醇(TC)、谷丙转氨酶(ALT)含量极显著高于对照组(P<0.01),甘油三酯(TG)、钙离子(Ca2+)含量显著高于对照组(P<0.05);而白蛋白(ALB)、谷草转氨酶(AST)含量极显著低于对照组(P<0.01);血糖(GLU)、总蛋白(TP)、镁离子(Mg2+)含量在实验组与对照组之间则无显著性差异。实验组血清中的蛋白质代谢产物和脂类物质明显高于对照组,但是血糖和总蛋白含量没有显著差异。

Abstract: The study was conducted to investigate the effects of starvation on serum biochemical indexes in 9-month-old large yellow croaker(Larimichthys crocea)at low temperature(13℃). Four hundred fishes were randomly divided into 2 groups, one group as control group was fed with formula feed, and the other as experimental group was starved. Eleven serum biochemical indexes were examined 30 d after experiment started. The results revealed that the UA, UREA, TC, and ALT of experimental group were extremely significantly higher than control group(P < 0. 01);while the ALB and AST of experimental group were extremely significantly lower than control group(P < 0. 01). Compared to control group, the TG and Ca2+ of experimental group were significantly higher(P < 0. 05). There was no significant difference in both TP and Mg2+ between experimental and control group.

Key words: low temperature, starvation, large yellow croaker(Larimichthys crocea), serum biochemical indexes
