Abstract

Community structure of fish and inhabiting status of endangered species, Cobitis choii and Gobiobotia naktongensis were investigated in the Ji Stream, a tributary of the Geum River Drainage System of Korea from May to October 2011. Ten to 23 fish species inhabited upper stream (St. 1~St. 4) with a Aa-Bb river type composed of mostly pebble and cobble bottoms, 16~28 species did middle stream (St. 5~St. 7) with a Bb type composed of mostly cobble and boulder bottoms, and 20-29 species did lower stream (St. 8~St. 10) with a Bb-Bc type composed of mostly sand bottoms. A total of 44 species belonging to nine families were found in the stream during the survay. The dominant species were in the order of Zacco platypus (37.2%), Pungtungia herzi (5.8%) and Pseudogobio esocinus (5.5%). Other abundant species included Acheilognathus lanceolatus (5.3%), Zacco koreanus (5.2%), Hemibarbus longirostris (4.9%) and Squalidus gracilis majimae (3.5%). Among residing species, 16 species were endemic to Korea, two (Cobits choii and Gobiobotia naktongensis) were endangered, and one (Micropterus salmoides) was non-indigenous. The similarity index based on species composition and abundance clearly delineated the fish community of the Ji Stream according to the three major sections, which were defined at the above. Dominance index gradually decreased toward downstream, while diversity, evenness and species richness indexes gradually increased toward downstream. The two endangered species, C. choii and G. naktongensis co-occurred at the lower stream due to the prevalence of a sandy substratum.

본 연구는 금강 지류인 충남 청양군 지천의 어류군집 및 멸종위기종 미호종개와 흰수마자의 서식현황을 파악하기 위하여 2011년 조사를 실시하였다. 지천 상류(St. 1~St. 4)는 하천형이 Aa-Bb형 또는 Bb형이고 하상구조는 자갈과 돌의 비율이 높았으며 10~23종의 어류가 서식하였고, 중류(St. 5~St. 7)는 하천형이 Bb형이고 하상구조는 돌과 큰돌의 비율이 높았으며 16~23종의 어류가 서식하였으며, 하류(St. 8~St. 10)는 하천형이 Bb-Bc형이고 하상구조는 모래의 비율이 높았으며 20~29종의 어류가 서식하였다. 전체 출현한 어종은 모두 9과 44종이었고, 우점종은 피라미 Zacco platypus (37.2%), 아우점종은 돌고기 Pungtungia herzi (5.8%)와 모래무지 Pseudogobio esocinus (5.5%)였으며, 그 다음으로 납자루 Acheilognathus lanceolatus (5.3%)와 참갈겨니 Z. koreanus (5.2%), 참마자 Hemibarbus longirostris (4.9%), 긴몰개 Squalidus gracilis majimae (3.5%) 등의 순으로 우세하게 출현하였다. 출현종 중 고유종은 16종(36.4%)으로 비교적 높게 나타났고, 멸종위기종은 미호종개와 흰수마자 2종이, 외래어종은 배스 Micropterus salmoides 1종이 출현하였다. 지점들 간의 군집유사도를 분석한 결과 상류(St. 1~St. 4)와 중류(St. 5~St. 7), 하류(St. 8~St. 10)로 나누어지고, 우점도는 하류로 갈수록 대체로 낮아지는 반면, 다양도와 균등도, 종풍부도 하류로 갈수록 대체로 높아지는 경향을 보였다. 하류에서 출현한 멸종위기종 미호종개와 흰수마자의 서식현황을 정밀조사한 결과, 두 종 모두 하상이 모래인 곳에 집단을 형성하여 서식하고 있어 주목되었다.
