CO-I서열의 생물정보학적 분석 결과 국내에서 유통되는 재첩류의 연체부는 일본재첩 (C. japonica) 과 재첩 (C. fluminea) 으로 동정되어 두 종이 혼재하여 유통되는 것으로 확인되었다. 일본재첩 (C. japonica) 과 재첩 (C. fluminea) 은 국내에서 서식하고 있으나, 섬진강 유역의 재첩 (C. fluminea) 은 개체수가 감소하여 거의 생산되지 않고 있으므로, 본 연구를 통해 확인된 재첩 (C. fluminea) 은 중국 수입산으로 예상된다.
The natives of the genus Corbicula have shown worldwide dispersion in recent times, which has caused great ecological and economic impacts on the introduced ecosystems. The species reported from the genus have been consumed as food and explored for medicine with pharmacological activity. Consequently, the demand of Corbicula sp. in the South Korean domestic market has increased and so also it’s associated import to the country. However, due to the absence of identification keys of imported Corbicula, the market is facing confronting situations. We hypothesized that the mitochondrial Cytochrome Oxidase I gene (CO-I) based molecular profiling could be a necessary technique for identification of Corbicula sp. in the South Korea domestic market. The genetic analysis identified both Corbicula japonica and Corbicula fluminea from the market foods. C. japonica and C. fluminea are inhabitants in Korea, but C. fluminea production has decreased in Seomjingang river basin. Therefore, C. fluminea identified from this study, is expected to be imported from China and would have a mixed sales in Seomjingang river side basin.
