中文摘要:
      2010年2月,对采自江苏吴江、广西三塘和广西南宁国家级良种场共3种不同来源的罗氏沼虾(Macrobra-chium rosenbergii)进行从幼体阶段至变态苗阶段的培育试验;干量容积法推算产苗量,计算育苗成活率。试验结果表明,3种不同来源幼体的育苗成活率分别为73.6%、65.2%和90.4%,成活率差异明显;其中,国家级广西南宁罗氏沼虾良种场的育苗成活率最高。在育苗生产中,必须注重罗氏沼虾亲本的种质复壮与培育,才能保证幼虾的质量,有利于提高其养殖成活率。
英文摘要:
      In February 2010,three different sources of Macrohrachium rosenbergii larvae from private breeding farm of Jiangsu Province,Guangxi autonomous region and state level seed breeding farm of Macrohrachium rosenbergii inNanning,were connected and used for juvenile culture. Dry larval volume method was adopted to calculate the juvenile amounts and larvae survival rate. Experiment results indicated that the survival rate of 3 different sources of Macrohrachium rosenbergii larval were 73 .6% ,65 .2% and 90.4%,respectively,having distinct difference among them. And the survival rate of larval from state-level seed breeding farm of Macrohrachium rosenbergii in Nanning was the highest. Macrohrachium rosenbergii seedling must focus on quality of the larvae.
