摘　　要： 采用投喂轮虫、轮虫与卤虫、卤虫3种不同的投喂模式饲喂中华绒螯蟹Ⅴ期溞状幼体,以其变态为大眼幼体的变态率、存活率以及实验结束时存活个体的重量、甲壳长、甲壳宽为评价指标,探讨了3种不同的饵料投喂模式对中华绒螯蟹大眼幼体生长发育的影响。结果表明:1)3种活饵料投喂模式的溞状幼体的存活率和96 h时变态率以单独投喂卤虫组最高,分别为33.33%±2.31%和86.2%±7.2%,但与另外两组差异不显著。2)3种不同活饵料投喂模式下的存活大眼幼体平均体重差异不显著;存活I仔蟹平均体重为(12.10±0.98)mg至(13.16±1.10)mg之间,单独投喂卤虫组体重显著高于其他两组(P<0.05)。3)3种不同活饵料投喂模式下的存活大眼幼体的平均甲壳长和甲壳宽均以单独投喂卤虫组的效果最好;3种不同活饵料投喂模式下I期仔蟹平均甲壳长和甲壳宽有显著差异,单独投喂轮虫组的甲壳长宽均小于其他两组;将卤虫作为单一饵料在促进中华绒螯蟹后期溞状幼体的变态和存活方面效果最好,其次轮虫卤虫混合组的饲喂效果优于单独投喂轮虫。 There are three different biological bait feeding modes to feed the Chinese mitten crab stage larvae, which are the individual feeding rotifers, rotifers and Artemia mixed feeding and the individual feeding Artemia.Parameters such as megalopae of metamorphosis to metamorphosis rate, metamorphosis megalopa of Megalopae survival rate and survival postlarvae （Megalopae and juvenile） weight after the experiment were used to discuss the investment and feeding modes of Chinese mitten crab.The results showed that among three biological bait feeding modes, the rates of zoea survival and metamorphosis at 96 h fed with the highest Artemia group were 33.33%±2.31% and 86.2%±7.2%, respectively.The average weights were not significantly different among the survival megalopa of the three different biological bait feeding modes.The average weight of survival of I larval was between （12.10±0.98）mg and （13.16±1.10）mg （P 〈0.05）.The average length of survival megalopa fed with the Artemia was the best.
