摘　　要：以本课题组选育的"闽优1号"及未经选育的普通大黄鱼(Larimichthys crocea)养殖群体为研究对象,比较了两者的白细胞吞噬活性、血清溶菌酶活性、杀菌活力、白蛋白及免疫球蛋白含量、血清及血细胞超氧化物歧化酶(SOD)活性等免疫指标的差异。结果表明:选育的"闽优1号"大黄鱼血清溶菌酶和血细胞SOD活力显著高于对照组(P<0.05),而血清中的免疫球蛋白含量低于普通养殖群体。在病原菌攻毒后8 d内,选育群体累积死亡率显著低于非选育群体,提示非特异性免疫在大黄鱼抗病免疫的早期阶段可能起着重要作用。We determined some immune parameters between the selected strain named Minyou No. 1 and common culture strain of large yellow croaker （Larimichthys crocea）. The results showed that the activities of lysozyme and SOD in blood cells of the Minyou No. 1 were significantly higher than those in the common group （P〈0.05）. While the immune globulin levels of Minyou No. 1 was lower than that of the common group. Furthermore, a lower cu- mulative mortality was found in Minyou No. 1 after artifically infected with Vibrio parahaemolyticus in 8 days, which suggested that non-specific immunity might play a more important role in the early stage of large yellow croaker defense against pathogenic-infection.
