Abstract

While an investigation on the old samples kept at collection room in National Institute of Fisheries Science (NIFS), we found a unique single specimen of burbot, Lota lota (54.7 cm in standard length) from Amnokgang River, North Korea on 14 April 1935. Burbot is the only stream dweller among members of the Gadiformes and found in the northern parts of Eurasia and North America. There was a little information in Korea, because it inhabits only the northern part of North Korea. This species is easily distinguished by having two dorsal fins, one anal fin, a barbel, and posterior of caudal fin rounded. This study provides detailed morphological characteristics and compares it with those of previous literatures on the North Korean L. lota.

국립수산과학원 수장고에 보관 중인 고시료에 관해서 조사하던 중 북한 압록강에서 1935년 4월 14일에 채집된 모오캐 1개체(표준체장 54.7 cm)를 발견하였다. 모오캐는 유라시아와 북미 대륙 북부에 서식하고, 대구목 어류 중에서 유일하게 담수에 서식하는 종이다. 또한 이 종은 북한의 압록강 인근의 북부에만 제한적으로 서식하여 우리나라에는 거의 알려진 바 없다. 모오캐는 2개의 등지느러미, 1개의 뒷지느러미 및 턱수염을 가지고 꼬리지느러미 후단이 둥근 특징으로 인해 쉽게 구별된다. 이 연구에서는 북한 모오캐의 자세한 외부 형태학적 특징을 제공하고 선행문헌에 기재된 내용과 비교하고자 한다.
