Reliable identification of seafood species is critical for fisheries management and product authentication, especially when morphological characteristics are lost during processing. In this study, a multiplex PCR system was developed to distinguish seven cuttlefish species (six Sepia spp. and Sepiella inermis) commercially distributed in the Korean seafood market. Species identity was first confirmed by amplifying a mitochondr...

In this study, a multiplex PCR assay was developed for the rapid and accurate identification of three Chionoecetes species (Chionoecetes bairdi, C. opilio, and C. japonicus) available in global seafood markets. The morphological similarity between imported female C. bairdi from Japan and native C. opilio in Korea complicates visual discrimination and raises concerns over potential mislabeling. To address this issue, mitochondr...
