| 摘 要： | (Hemiculter leucisculus)和鱇白鱼(Anabarilius grahami)分别是抚仙湖的外来鱼类和土著鱼类。研究了不同营养状态(低、中、高)水体中二者肝脏酶活性的变化;其中,低营养状态水体组是中、高营养水体组的对照。养殖40d后,随着水体营养状态的提高,和鱇白鱼肝脏中的谷草转氨酶(AST)、谷丙转氨酶(ALT)和乳酸脱氢酶(LDH)活性均逐渐降低;中、高营养水体中歺鱼又的超氧化物岐化酶(SOD)活性显著低于对照组,而3个处理组鱇白鱼的超氧化物岐化酶活性没有显著差异。由此推测,富营养化有可能减弱歺鱼又和鱇白鱼肝脏的正常功能,而歺鱼又在高营养水体中可能更容易受到氧化胁迫的威胁。

| Abstract: | Hemiculter leucisculus is an exotic fish for Fuxian Lake,and Anabarilius grahami is a native fish for Fuxian Lake.Changes of hepatic enzymatic activity for H.leucisculus and A.grahami rearing the waters with different water trophic status were studied in this experiment.Fishes were reared in three types of water(LTS,the low-trophic-status water;MTS,the moderate-trophic-status water;and HTS,the high-trophic-status water).The group reared in LTS also served as the control of the groups reared in MTS and HTS f... |
