英文摘要	在水温25~27℃、盐度13~16、PH值7.5~8.5、连续充气的条件下,以PVC管和筛绢网制成的网箱进行拟穴青蟹(Ⅰ组)和锯缘青蟹(Ⅱ组)两种蟹苗的中间培育。结果表明:网箱培育的拟穴青蟹与锯缘青蟹的蜕壳率分别为47.28%和42.72%,彼此差异显著(P<0.05);死亡率分别为32.88%和42.19%,彼此差异显著(P<0.05)。Ⅰ组、Ⅱ组的增肉系数分别为21.10,14.17;甲长增长率分别为337.25%,304.99%;甲宽增长率分别为275.00%,204.42%。Ⅰ组、Ⅱ组的甲长与甲宽的关系分别为yⅠ=1.6455XⅠ-1.8486,yⅡ=1.7406XⅡ-2.7513;甲宽与体质量的关系分别为WⅠ=0.0264EⅠ0.2818X,WⅡ=0.0308E0Ⅱ.2772X;在本实验条件下青蟹密度为417只/M2时的存活率最高。表明水泥池套养网箱的中间培育模式是可行的。; Under the condition of water temperature of 25～27℃,pH of 7.5～8.5,salinity of 13～16 and continuous aeration,the experiment was conducted on two different species of juvenile crabs(Scylla paramamosain,Scylla serrata) with the cages which were made of PVC pipe and silk screen net in pools.The result showed the rates of mortality were Scylla paramamosain( 42.19%) and of Scylla serrata (32.88% ) ; the molting rates were Scylla paramamosain(42.72%) and of Scylla serrata (47.28% ).The weight coefficient were the groups Ⅰ(21.10) and the group Ⅱ(14.17); the increase of carapace length were the groups Ⅰ(337.25%) and the group Ⅱ(304.99%; the increase of carapace width are 275.00%,204.42%,had signification difference(p<0.05).The relationships between the carapace length and width of three groups (Ⅰ,Ⅱ) were yⅠ= 1.6455x -1.8486,yⅡ = 1.7406x -2.7513; the relationships between the carapace width and weight of two groups were wⅠ = 0.0264e0.2818x,w Ⅱ= 0.0308e0.2772x.In conclusion ,under the condition of this experiment ,the density of juvenile crab was 417/ m2 had the highest rate of survival,the model of cultured.crabs with the cages which were made of PVC pipe and silk screen net in pools is feasible.; 福建省科技计划重点项目(2008X10040);国家高技术研究发展计划863项目(2006AA10A-406)资助
