| 摘 要： | 目前应用显微镜技术很难进行鱼卵种类的准确鉴定,本文尝试采用DNA技术开展鱼卵的鉴定工作。以带鱼(Trichiurus haumela)鱼卵为研究对象,采用苯酚-氯仿法提取了其DNA基因组,并采用PCR及克隆测序的方法,对其18S rDNA序列进行了测定与初步分析。结果表明,提取的带鱼(T.haumela)鱼卵DNA基因组片段长度约23kb,PCR扩增片段长度约1.8kb;带鱼(T.haumela)鱼卵18S rDNA与其它已知鱼类的18S rDNA序列具有一定的差异性,可以用其进行带鱼(T.haumela)鱼卵的初步鉴定。

| Abstract: | For the moment,it is difficult to distinguish different species of fish eggs with microscopical technique,and that DNA technique was applied to identify species of fish eggs in the paper. The Trichiurus haumela fish eggs was tested and its genome was extracted with the method of phenol-chloroform and its 18S rDNA sequence was also studied with PCR and clone technique. The results showed that the gene sequence length of the Trichiurus haumela fish eggs was about 23 kb,and that the sequence length of PCR prod... |
