摘　　要：2000年3月30日至5月6日,首次在低洼盐碱地进行了塑料大棚培育五期幼蟹试验。经过37天精心培育,在200m2的土池中,1.5kg、19.5万只大眼幼体育出五期幼蟹36.7kg、8.81万只,蟹苗增重倍数24.5,成活率45.2%。实验的成功对于洼区解决蟹苗来源、推广河蟹养殖,改善养殖结构,提高经济效益将起到积极作用。An experiment of rearing young crabs in earth pond of plastic sheet shelf was done in saline-alkali wetland at Xindianwa of Yucheng city,Shandong Province during March 30-May6, 2000. About 195 thousand (1.5kg in weight) of juvenile crabs were stocked into the pond , after 37days rearing, 88.1 thousand (36.7kg in weight) of young crabs of Ⅴ stage were obtained, the total weight gained was 24.5 times of the stocking weight and the survival rate was 45.2%. Based on the experiment, we dovelop a new rearing technology for young crabs of Ⅴ stage in saline-alkali wetland.
