报道了凡纳滨对虾无特定病原 (SPF)育苗技术及养成试验效果。试验结果表明 ,平均单位水体出苗12 .88× 10 4ind/m3 ,育苗成活率 86 .15 % ;2 0 0 2年养成试验的对虾平均体重 34.318g/ind ,平均体长 14 .75 5cm/ind ,而对照池对虾平均体重 2 5 .793g/ind ,平均体长 13.0 33cm/ind。养成试验显示 ,放养优质无特定病原虾苗的池塘 ,平均可增产 4 6 .4 5 % ,成活率提高 7.4 6个百分点。
Reported that there is no specific pathogen (SPF) nursery technology and the experimental results of Litopenaeus vannamei. The results showed that the average unit water body emergence 12 .88 × 10 4ind / m3, seedling survival rate 86.15%; developed in 2002 the average body weight of prawn 34.318g / ind, the average length of 14.575 5cm / ind, while the control pond shrimp average weight 25.793g / ind, the average length of 13.033cm / ind. Cultivation test shows that stocking high-quality ponds without specific pathogen shrimp, the average yield increase 46.45%, survival rate increased 7.46 percentage points.
