Abstract

Analysis of the fish community in Yeongwol Hanbando wetland in Korea was investigated from April to October 2012. During the survey period, total 33 species belonged to 10 families and 7,107 individuals. There were 18 Korean endemic species (52.94 %), including to Acheilognathus signifer. Also, the dominant species were Zacco koreanus at St. 1, 2, 3 & 5, as well Acheilognathus signifer at St. 6, and Pseudopungtungia tenuicorpus at St. 7, respectively, and these species were inhabited in the midstream. But at St. 4, Carassius auratus was dominance, so there appeared to characteristics of downstream or lentic habitat. Also, according to the similarity analysis on fish species and their individuals in each sites, they were divided into three major groups (A,B and C). Among them, group C (St. 4) showed the special inverse characteristics as a stagnant pond. unlike the river branch (group A) and anthropogenic disturbances receiving stream point (group B), Therefore, the ecosystem of Yeongwol Hanbando wetland is considered to very unique and these characteristics are not found in other stream ecosystems and it is confidently believed that the ecological value is very high.

2012년 4월부터 10월까지 영월 한반도습지의 어류군집에 대하여 조사한 결과는 다음과 같다. 조사기간 동안 출현한 어류는 총 10과 33종 7,107개체였으며, 이 중 한국고유종은 묵납자루를 포함하여 총 18종(52.94%)이었다. 또한 각 지점별 우점종은 St. 1, 2, 3, 5에서는 각각 참갈겨니(Zacco koreanus)였으며 St. 6에서 돌고기(Pungtungia herzi), 그리고 St. 7에서 묵납자루(Acheilognathus signifer)로서 하천 중상류역에 서식하는 어종이 우점하였으나, St. 4에서는 붕어(Carausius auratus)가 우점하여 하천의 중 하류역 또는 정수역의 특성을 나타내었다. 또한 각 조사지점을 대상으로 유사도 분석을 실시한 결과 크게 3그룹(A, B, C)으로 나뉘어졌으며, 이중 그룹 C(St. 4)는 하천 지점(그룹 A)과 인위적인 교란을 받은 하천지점(그룹 B)과는 다르게 정수역의 특징을 나타내었다. 이와 같이 영월 한반도습지는 하천과 정수역의 특징을 지닌 매우 독특한 습지생태계로 판단되며, 생태학적 가치가 매우 높은 것으로 확신된다.
