不同游泳运动对菊黄东方鲀非特异性免疫的影响

通过水槽实验法，观察了菊黄东方鲀的游泳行为，测量了其爆发游速及临界游速，同时观察了鱼体过氧化氢酶、溶菌酶、超氧化物歧化酶等的活性变化，分析了游泳对菊黄东方鲀免疫力影响，为菊黄东方鲀的健康养殖及科学的增殖放流提供参考。结果表明:体长在（18.1-19.8）cm的菊黄东方鲀的临界游速在45-62cm/s,体长在（18.8-20.6）cm的菊黄东方鲀的爆发游速为（58.5-78.2）cm/s；与对照组相比，爆发游速实验组菊黄东方鲀肝脏过氧化氢酶、溶菌酶、超氧化物歧化酶的活性均高于对照实验组菊黄东方鲀（P?0.05）；临界游速实验组菊黄东方鲀溶菌酶高于对照组（P?0.05），血液中的超氧化物歧化酶和肝脏过氧化氢酶的活性没有显著变化(P>0.05)。研究表明，急性应激反应对超氧化物歧化酶、过氧化氢酶、溶菌酶的活性影响较大。

Effects of Different Swimming Exercises on Nonspecific Immunity of Takifugu flavidus

This experiment analyzed and researched the changes of the activities of Catalase,Lysozyme and Superoxide Dismutase in Takifugu flavidus body, to provide a reference of enhancement releasing and resources recovery.The results showed that, Takifugu flavidus with the body length between 18.1cm to19.8cm,its critical swimming speed was 45cm/s to 62cm/s:Takifugu flavidus with the body length between 18.8cm to 20.6cm,its burst swimming speed was 58.5cm/s-78.2cm/s. Comparing with control group, the activities of Catalase ,Lysozyme and Superoxide Dismutase in liver of burst swimming group were higher P<0.05); Activity of the Lysozyme of critical group was higher than that of control group(P<0.05),there were no obvious changes of Catalase activity or Superoxide Dismutas activity(P>0.05).The research finds that acute stress reaction has a greater effect of the activities of Catalase, Lysozyme and Superoxide Dismutase.
