Abstract:

With the development of molecular biotechnology, methods for identification of seafood species are developed from protein to DNA. At present, the main DNA-based methods for species identification are FINS, PCR-RFLP, and specific-PCR, which have been used to identify the species of fresh, frozen, and pickled or canned seafood. However, qualitative and quantitative methods for identification of the mixed seafood species remain to be resolved. The gene databases play an important role in identifying species and are valuable information resources for identification of seafood species. In this paper, recent progresses of major DNA-based methods for identification of seafood species are reviewed and the perspec-tives of this field are discussed.

Key words: DNA biotechnology, seafood, species identification
