초록

전라북도 남원시 식정동에서 채집한 한국 고유종인 섬진자가사리를 암, 수 각각 9마리와 8마리의 핵형 분석을 실시하였다. 섬진자가사리의 염색체 수는 2n=42로 조사되었고, 핵형은 28 metacentric과 14 submetacentric으로 이루어져 있었으며 FN은 80이었다. 이번 결과에서 배수체와 암수 간의 성적이형은 발견되지 않았다. 섬진자가사리는 근연종들과 염색체 수는 같았으나, 핵형에서는 차이를 보였다.

The karyotype analysis of Liobagrus somjinensis, an endemic Korean freshwater fish with restricted waters and a new species of torrent catfish was carried out from nine females and eight males of Somjingang River, Sikjeong-dong, Namwon-si, Jeollabuk-do, Korea. The diploid number of chromosomes was 42, and its karyotype was composed of 28 metacentrics and 14 submetacentrics; 84 FN (fundamental number). Polyploidy and sex dimorphism were not observed in the present species. The chromosome number of L. somjinensis was the same as its congeners, but there was a difference in karyotypes.
