Abstract

One specimen of Albula argentea (296.3 mm in standard length), belonging to the family Albulidae, was collected in a set net in the coastal waters of Jejudo Island, Korea. As the adult A. argentea has not been caught from Korean waters, we described its morphological characters based on the collected specimen and compared them with those of the previous reports on A. argentea and A. koreaus. As a result, the present specimen was characterized by having 68~73 pored lateral line scales (vs. 77~78 for A. koreana), 72~73 vertebrae pored lateral line scales (vs. 77~80) and none streak on the check (vs. yellowish streak). Molecular analysis using the mitochondrial cytochrome b DNA sequences was also conducted to confirm the correctness of species identification and taxonomic status of the sample.

여을멸과에 속하는 Albula sp. 1개체를 제주도 연안의 정치망에서 채집하여 형태적 특징을 기술하였다. 이 개체는 73개의 측선공과 72개의 척추골, 그리고 뺨에 무늬가 없는 특징으로 형태적으로 Albula argentea로 동정되었다. 보다 명확한 종 동정을 위해서 표본조직으로부터 미토콘드리아 사이토크롬 b 염기서열을 얻은 후 기존에 보고된 10종의 Albula spp.와 비교 분석한 결과, 분자생물학적으로도 A. argentea와 동일종으로 나타났다.
