摘　　要：本文研究了中华绒螯蟹7日龄大眼幼体经55．24—73．66mGy低剂量中子刺激处理后。不同养殖时期生化参数变化与生长的关系。结果表明，处理与对照相比蛋白中巯基（．SH）含量提高23．40％－69．59％，自由基水平降低7．67％－32．86％，蛋白含量提高4．99％～22．69％，碱性磷酸酶（AKP）降低、羟脯氨酸（Hyp）升高，蟹壳颜色加深，中华绒螯蟹幼蟹生长快，抗逆能力增强，规格整齐，并有抑制性早熟的表现。This paper was dealt with the relationship between biochemical indexes and different growth stages of Eriocheir sinensis megalopa treated with Low-dose Neutron at 55.24 to 73.66mGy. It showed that some biochemical component indexes were increased, such as-SH group in protain （between 23.40% to 69.59%）, albumen （between 4.99% to 22.6%） and Hyp compared with CK. However, free radical level （ between 7.67 % to 32.68 % ） and AKP were decreased. The carapace color was turned into darker than that of CK; Antibacterial the body size of treated Eriocheir sinensis megalopa became with a low dose neutron treatment. imnmnity of younger crab during the growing stage was increased, uniform and early sexual maturity was inhibited in a certain degree
