摘　　要：比较了湖泊和池塘养殖环境对中华绒螯蟹(Eriocheir sinensis)组织中乳酸和活性氧含量的影响。结果显示:性腺、肝脏和肌肉组织中的乳酸含量,阳澄湖、太湖养殖蟹显著低于同水系池塘养殖蟹、特级蟹显著低于个体小的等外品蟹、雄蟹低于雌蟹、性腺和肝脏低于肌肉。9—11月份,湖养蟹组织中的乳酸含量较塘养蟹更早、更加快速地降低。肌肉组织中活性氧(ROS)含量测定显示,特级蟹稳定地低于等外品雌蟹,雄蟹低于相同养殖环境中同规格雌蟹。结果表明,乳酸和ROS含量或机体抗氧化能力的指标对于阳澄湖大闸蟹的品质和呈味特色是一个值得关注和深入研究的指标。The lactic acid and ROS content in tissues of Eriocheir sinensis raised in lake and pond were investigated in this paper. The results showed that, the lactic acid content in gonad, liver and muscle from Lake Crabs, no matter Yangcheng Lake or Taihu Lake,were extremely lower than that from pond around the lakes,while the lactic acid content of the top grade mature crabs were lower than that in small crabs. At the same time,lactic acid content in male were lower than that in female,and the lactic acid existed more in muscles than in the other two kinds of tissue. Moreover,the lactic acid in tissues fell earlier and more rapidly in lake crabs than that in pond crabs from September to November. The ROS detection in muscle reveals that the top grade mature crabs contain less ROS than small female crabs,and the male one always had less ROS than female one of the same size. The result elucidated that lactic acid,ROS content or the indicator of oxidation resistance could be a matter of concern in the quality and taste of Yangcheng Lake crab,and they deserved atlen-tion and in-depth study.
