摘要: 基于Cytb基因,采用直接测序的方法,对阿拉斯加鳕鱼ITS1、大西洋庸鲽ITS2、牙鳕ITS3和欧洲黄盖鲽ITS4 4种鱼进行初步鉴定。结果表明,ITS1与Theragra chalcogramma(DQ356946)序列同源性达99%;ITS2与Hippo-glossus hippoglossus(EU492151)序列同源性达98%;ITS3与Merlangius merlangus(AY946299)序列同源性达98%;ITS4与Limanda limanda(EU492119)序列同源性达99%。本研究又对50份样品进行鱼种真实性鉴定,结果发现大部分样品与产品包装上的名称相符。

关键词: 鱼产品, Cytb基因, 测序

Abstract: In this study Theragra chalcogramma,Hippoglossus hippoglossus,Merlangius merlangus and Limanda limanda were identified by sequence method,based on Cytb gene.The preliminary results showed that ITS1 was similar with Theragra chalcogramma(DQ356946) by 99%,ITS2 was similar with Hippoglossus hippoglossus(EU492151)by 98%,ITS3 with Merlangius merlangus(AY946299) by 98%,ITS4 with Limanda limanda(EU492119) by 99%.We also detected 50 samples about fish authenticity identification,and testing results also showed that most samples are consistent with their name.
