【Abstract】 The paper deals with the specific pathogen free(SPF) Litopenaeus vannamei breeding and grow-out experiments. The results showed that the seed out the water body was 12.88×104 ind/m3 with the seed survival rate of 86.15%. The average weight and average length of shrimp were 34.318g/ind and 14.755 cm/ind respectively in grow-out experiment in 2002 as compared to 25.793 g/ind and 13.033 cm/ind respectively for the control ponds. It testified that the average production could increase 46.45% and the survival rate could increase 7.46 by breeding fine specific pathogen free Litopenaeus vannamei.更多还原
