Abstract

The purpose of this study was to analyze fish communities in the Wonju stream located in Wonju-si in Gangwon-do, and to evaluate the health of the stream through past and present changes. We performed investigations four times from May 2015 to September 2016. In the survey, 5,201 individuals which belonged to 27 species and 9 families were collected. Zacco platypus was the dominant species and Pungtungia herziwas the subdominant species. Eight Korean endemic species (Acanthorhodeus gracilis, Zacco koreanus, Coreoleuciscus splendidus, Squalidus gracilis majimae, Microphysogobio yaluensis, Iksookimia koreensis, Koreocobitis rotundicaudata, Coreoperca herzi) were observed and showed a ratio of 16.54%. The fish community of dominance ($0.72{\pm}0.10$), diversity ($1.37{\pm}0.32$), evenness ($0.61{\pm}0.13$), and richness ($1.70{\pm}0.23$) were evaluated. According to our analysis of tolerance guilds, the total individual number of intermediate species was higher than the sensitive and tolerant species. As a result of the trophic guild analysis,the omnivore and insectivore species were relatively high. The value of the qualitative habitat evaluation index (QHEI) in the wonju stream was averaged 121.2 (${\pm}23.4$), indicating a suboptimal condition. Stream health showed that the fish assessment index (FAI) value was an A to C grade in the Wonju stream. A correlation coefficient analysis with FAI and various factors was analysed statistically, and had a high correlation in QHEI, with the omnivore species, insectivore species, intermediate species, sensitive species, dominance, diversity, evenness, and richness.

본 연구는 강원도 원주시에 위치한 원주천의 현재의 어류상을 파악하고, 과거와 현재의 변화를 통하여 하천 건강성을 평가하고자 하였다. 현지조사는 2015년 5월부터 2016년 9월까지 총 4회 조사를 실시하였다. 조사결과 총 9과 27종 5,201개체가 출현하였으며, 피라미(Zacco platypus)가 우점하고, 돌고기(Pungtungia herzi)가 아우점한 것으로 나타났다. 한국고유종은 총 8종으로 고유종 빈도는 16.54%로 분석되었다. 군집분석 결과 평균 우점도지수는 0.72 (${\pm}0.10$), 다양도지수는 1.37 (${\pm}0.32$), 균등도지수 0.61 (${\pm}0.13$), 풍부도지수 1.70 (${\pm}0.23$)으로 분석되었다. 내성도 길드 분석 결과 중간종의 개체수 비율이 높게 나타났으며, 섭식도 길드 분석 결과 전반적으로 잡식종의 비율이 상대적으로 높게 분포하였다. 물리적 서식지 평가지수(QHEI) 분석결과 평균 121.2(${\pm}23.4$)로 양호한 서식처 환경을 나타냈으며, 어류평가지수(FAI)를 분석한 결과 대부분 A~B등급으로 하천건강성이 양호한 것으로 분석되었다. FAI와 다양한 항목 간의 상관성 분석결과 QHEI, 잡식종, 충식종, 중간종, 민감종, 우점도, 다양도, 균등도, 풍부도는 통계적으로 높은 상관성을 갖는 것으로 분석되었다.
