뱀장어속(Anguilla)의 뱀장어(A. ioponica)와 무태장어(A. marmoruta) 및 꾀붕장어(Anago anogo)의 유전적 특징과 종간 유연관계를 밝히기 위하여 isozyme 분석과 mtDNA 분석을 실시하였다. Isozyme 분석결과 20개의 효소 및 비효소단백질에서 총 39개의 유전자를 검출하였고 각종 특유의 genetic marker를 확인하였다. 3종의 평균 유전적 변이는 뱀장어가 HD=0.057. HG=0.065, 무태장어는 HD=0.067 HG=0.053, 체불장어가 HD=0.018. HG=0.020으로 각각 나타났다. 뱀장어와 무태장어의 평균 종간유전적 근인관계는 S=0.420 (D=0.869)로 멀게 나타났다. 6 base를 인지하는 10종류의 제한효소를 처리한 결과 mtDNA 절편양상은 각 종내에서 동일하게 나타났으나 각종간에 차이를 보였고, 종간 평균염기 치 환율은 뱀장어와 무태장어가 p=3.4%, 뱀장어속 2종과 꾀붕장어는 p=9.6%로 나타났다.

The taxonomic revision of the family Congridae was made based on the specimens collected from the south-western coasts of the Korea from June 1988 to Oct. 1993. The family Congridae was classified into 8 species belonging to 6 genera. based on the external and internal morphological characters : Anago anago, Ariosoma anagodies, Ariosoma shiroanago shiroanago, Conger myriaster, Conger japonicus, Gnathophis nystromi nystromi, Rhechias retrotincta and Uroconger lepturus. Among the species reported as the congrid eels from Korea until now, four species were transferred into different generic or specific name Conger flavirostris into Ariosoma anagoides ; Astroconger myriaster into Conger myriaster ; Congrina retrotincta into Rhechias retrotincta and Rhynchocymba nystromi into Gnathophis nystromi nystromi. A Korean congrid eel, Ariosoma shiroanago shiroanago, was reported for first time in Korea. Intergeneric characters of the family Congridae were the form of the lateralline scales, the state of the tip of tail, the segmented state of the dorsal and anal fin rays, the existance of the supraoccipital bone and of lateral ethmoid process of the skull, the origin of dorsal fin and the forms of upper labial flange. The interspecific classification was made according to the characters such as the numbers of sensory pores of head part and in front of vent, teeth rows and numbers of upper and lower jaw, the numbers of vertebrae, the body color, the shapes of the head part, the color of intestine, the size of eye, the structure of air bladder and the number of branchiostegal rays. A new key on the taxonomical characteristics to the genera and species of the family Congridae has been estabilished and their distribution in Korea is described.
