초록

최근 우리나라에서는 필리핀 현지에서 채집되는 Anguilla marmorata와 A. bicolor pacifica의 실뱀장어 수입량이 증가하는 추세이다. 본 연구에서는 2014년 5월과 7월에 필리핀의 루손섬 북쪽과 민다나오섬 남쪽의 기수지역에서 채집된 실뱀장어를 대상으로 현지에서 적용 가능한 등지느러미의 위치와 꼬리지느러미의 색소세포 침착형태 등의 외부 형태적 특징을 바탕으로 한 판별기법을 유전자분석과 함께 실시하여 그 유효성을 검토하였다. 5월 루손섬 북쪽의 시료는 A. marmorata가 90% 이상이었으며, 민다나오섬 남쪽의 시료는 A. mamorata와 A. bicolor pacifica가 각각 36.7%, 63.3%였다. 7월의 민다나오섬 남쪽의 시료는 A. mamorata와 A. biolor pacifica가 각각 46.7%, 53.3%로, 두 종간의 외부 형태학적 특징을 바탕으로 하는 종 분류기법은 유전자분석 결과와 일치하여 유효한 것으로 사료된다.

Recently, import supply of glass eels from Philippines has been increased in South Korea, and the species distinction was very important to import traders and Anguilla marmorata and A. bicolor pacifica are major species at Philippines. In this study, the species distinction and the rate were researched targeting imported glass eels from the estuaries of North Luzon and the South Mindanao in May and July, 2014. Dorsal fin position and pigmentation pattern at caudal fin are the trait standard for species distinction. The results about morphological identification were coincide with the result of the genetic identification, and the regional distribution of A. marmorata rate was over 90% at North Ruzon in May. However, the rates of A. bicolor pacifica and A. mamorata were 63.3% and 36.7% in May, and were 53.3% and 46.7% in July respectively at South Mindanao.
