Species Identification of Cytb Gene in Fish Product

doi:10.7668/hbnxb.2011.S2.003

Abstract

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.

Key words: Fish product, Cytb gene, Sequence
