| 摘 要： | 从引进的无特定病原（SPF）凡纳滨对虾（Litopenaeusvannamei）亲虾生产的子代中挑选出生长快、体格健壮等性状良好的个体作为亲本建立16个第一代选育家系，并经223d饲养和感染实验从中挑选出抗病力强、生长快的家系建立21个第二代家系．抗WSSV实验的结果表明：第一代选育各家系经感染wssv（投喂）后的成活率在0～61．5％之间，平均成活率为30．0％±16．5％；第二代选育家系成活率在14．5％～70．0％之间，平均成活率为37．3％±15．2％，比第一代提高24．3％．21个第二代选育家系经28d的生长实验显示：21个选育家系体长特定生长率在0．00l5～0．0142之间，体重特定生长率在0．0053～0．0279之间；两代选育家系抗病与生长的结果表明：抗病较强的家系生长快，抗病差的家系生长慢，但抗病最强或生长最快的家系，其对应的生长或抗病性能则不理想． |

| Abstract: | Sixteen fast-growing and robust pairs of imported specific pathogen-free Litopenaeus vannamei were selected as first-generation breeding families.After 223 days of breeding and infection tests,21 fast-growing pairs with strong disease resistance were selected as second-generation breeding families.White spot syndrome virus(WSSV) challenge tests showed that the survival rates after the oral infection of the first-generation breeding families were 0~61.5%(mean: 30.0%±16.5%) and those of the second-generation breeding families were 14.5%~70.0%(mean: 37.3%±15.2%),24.3% higher than those of the first-generation breeding families.After rearing for 28 days,the body length specific growth rates of the 21 selected second-generation breeding families were 0.001 5~0.014 2,and the specific body weight increases were 0.005 3~0.027 9.The regression of the survival rate(Y) and the body length specific growth rate(X1) was established as Y=-23.484 X1+0.485 9(r=0.558),and the regression of the survival rate(Y) and the body weight specific growth rate(X2) was established as Y=-13.921 X2+0.541 2(r=0.557).The resistance to WSSV and the growth of two generations of breeding families indicated that the growth rates of more resistant families were much faster than more susceptible families with a slower growth rate.However,the most resistant or fastest growing families performed poorly in growth rates or disease resistance. |
