Abstract

The karyotype analysis of Kichulchoia brevifasciata was carried out, known as an end-angered small endemic cobitid fish of Korea. Five females and one male were collected from Geum-san-myeon, Goheung-gun, Jeollanam-do, Korea and its gill, kidney and digestive tract tissues were treated by flame-drying technique. The karyotype was found to be 2n= 48 from 33 cells; 16 meta-submetacentric and 32 subtelo-telocentric chromosomes; 64 FN (fundamental number). This karyotype showed a remarkably different karyotype formula from Niwaella multifasciata which is closely related to this species.

멸종위기에 처한 한국 고유종인 미꾸리과(Cobitidae) 소형어류 좀수수치, Kichulchoia brevifasciata의 핵형을 분석하였다. 전라남도 고흥군 금산면에서 6개체를 채집하여 핵형분석 결과 염색체 수는 2n=48 으로서 16 meta-submetacentric, 32 subtelo-telocentric chromosomes로 구성되어 있었으며 FN=64 이었고 유연관계에 있는 수수미꾸리, Niwaella multifasciata와 핵형과 구성에 있어 큰 차이를 나타냈다.
