Abstract

The microhabitat of Iksookimia hugowolfeldi was surveyed in two sites, Geogeum Island and Jangheung. I. hugowolfeldi in Geogeum Island inhabits mainly pool. This water system consists of sand and cobble and has a shallow water (0.1~0.8 m depth) with slow currents (0.1 m/s). 0+ years old inhabits pool consist of sand and lives in a less than 0.3 m depth. I. hugowolfeldi in Jangheung population inhabits mainly pool consists of sand and cobble and lives in a shallow water (0.1~0.8 m depth) with slow currents (0.1 m/s) compared to the stream of Geogeum Island. With some different fish species, sympatric species collected at Geogeum Island and Jangheung population are 7 species in 4 family identically in the two sites.

잉어목 미꾸리과에 속하는 한국고유종 남방종개의 하상구조, 유속, 유폭, 하폭 등의 서식처 특성을 전라남도 고흥군 금산면 거금도와, 전라남도 장흥군 안양면 수문리 지점에서 조사하였다. 거금도 개체군은 유속이 0.1 m/s, 수심 0.8 m 이하의 하상이 모래와 잔자갈로 이루어진 소에서 집단으로 서식하였다. 또한 당년생 치어는 수심이 0.3 m 이하인 모래 하상의 소에 대부분 분포하였다. 장흥 개체군 또한 유속이 0.1 m/s, 수심 0.8 m 이하의 하상이 모래와 잔자갈로 이루어진 소를 선호하였다. 거금도와 장흥의 동소서식종은 각각 4과 7종으로 나타났으며 집단내에서 남방종개는 우점 및 아우점하는 것으로 확인되었다.
