摘　　要：利用3口池塘共1.14 hm^2进行锯缘青蟹大眼幼体与凡纳滨对虾的混养试验,投放锯缘青蟹大眼幼体8500只,凡纳滨对虾苗2.03×10^5尾,经96-129 d的养殖,收获锯缘青蟹729.1 kg,凡纳滨对虾2804.3 kg;锯缘青蟹平均312 g/只,凡纳滨对虾57.5尾/kg;锯缘青蟹大眼幼体成活率27.5%,凡纳滨对虾成活率79.4%。试验结果表明,锯缘青蟹大眼幼体可以直接投入池塘中与凡纳滨对虾混养,将为今后大规模发展锯缘青蟹养殖摸索出一条有效途径。The crab （Scylla serrata） megalops and white leg shrimp （Litopenaeus vannamei） juveniles were stocked into 3 ponds with a total surface area of 1.14 hm^2 at a rate of 8 500 and 203 000 individuals, respectively, and polycultured for 96 -129 days. It were found that 729.1 kg of the crab with average body weight of 312 g, and 2804.3 kg of the shrimp averaging 57.5 individuals per kg were obtained. The crab had a final survival rate of 27.5%, and the shrimp 79.4%, indicating that both the crab and the shrimp can be polycultured.
