| 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。

| Abstract: | 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 immunity of younger crab during the growing stage was increased,the body size of treated Eriocheir sinensis megalopa became uniform and early sexual maturity was inhibited in a certain degree with a low dose neutron treatment. |
