Abstract

We investigated the characteristics of fish communities and habitat status of endangered species Rhodeus pseudosericeus in Heuk Stream, a tributary of the Han River, from April to October 2018. During this period, we collected 47 species of 14 families from 10 survey stations using kick nets, cast nets, and long bag set nets. The dominant and subdominant species were Zacco platypus (37.6%) and Z. koreanus (13.8%), respectively. The next most abundant species were Squalidus gracilis majimae (11.1%), Pungtungia herzi (7.7%), Rhodeus pseudosericeus (5.0%), Microphysogobio yaluensis (4.3%), and Hemibarbus longirostris (3.0%). Among the fish collected, 19 species (40.4%) were Korean endemic species. Endangered species were R. pseudosericeus and Acheilognathus signifer while exotic species were Micropterus salmoides and Oncorhynchus mykiss, and land-locked species were Plecoglossus altivelis and Rhinogobius brunneus. The community analysis showed that the dominance and evenness indexes were mostly low and that the diversity and richness indexes were high. Moreover, the river health (index of biological integrity) was mostly excllent (1 site is good, 9 sites are very good). R. pseudosericeus inhabited widely from St. 3 to St. 9 in Heuk Stream, and its population size was large. Age groups for R. pseudosericeus estimated by the frequency distribution of total length in spawning season (April) indicated the 32~45 mm group as 1-year old, the 46~59 mm group as 2-years old, 60~69 mm group as 3-years old, and the 70~89 mm group as 4-years or older. Total length range of male and female was similar, and the sex ratio of female (426) to male (394) was 1 : 0.95. A. signifer, which had been released in Heuk Stream, inhabited from St. 4 to St. 5, but its population size was small. Lastly, this paper discusses a conservation plan for fish in Heuk Stream.

한강지류 흑천의 어류군집 특성 및 멸종위기종 한강납줄개의 서식양상을 밝히기 위하여 2018년 4월부터 10월까지 조사를 실시하였다. 조사기간 동안 10개 지점에서 족대와 투망, 일각망으로 채집된 어류는 14과 47종이었다. 우점종은 피라미(Zacco platypus, 37.6%), 아우점종은 참갈겨니(Z. koreanus, 13.8%)였고, 그 다음으로 긴몰개(Squalidus gracilis majimae, 11.1%), 돌고기(Pungtungia herzi, 7.7%), 한강납줄개(Rhodeus pseudosericeus, 5.0%), 돌마자(Microphysogobio yaluensis, 4.3%), 참마자(Hemibarbus longirostris, 3.0%) 등의 순으로 우세하게 출현하였다. 출현종 중 한국고유종은 19종(40.4%)이었고, 멸종위기종은 한강납줄개와 묵납자루(Acheilognathus signifer)가, 외래어 종은 배스(Micropterus salmoides)와 무지개송어가(Oncorhynchus mykiss)가 채집되었으며, 육봉형 어종은 은어(Plecoglossus altivelis)와 밀어(Rhinogobius brunneus)가 채집되었다. 군집분석에서 대부분 우점도와 균등도는 낮고 다양도와 풍부도는 높게 나타났으며, 하천건강성은 매우 양호(매우 양호: 9개 지점, 양호: 1개 지점)로 나타났다. 한강납줄개는 St. 3~St. 9까지 폭넓게 서식하고 있었으며 개체군 크기가 컸다. 전장빈도분포도로 한강납줄개의 연령을 추정한 결과, 산란기인 4월을 기준으로 암수 구별없이 전장 32~45 m는 만 1년생, 전장 46~59 mm는 만 2년생, 전장 60~69 mm는 만 3년생, 전장 70~89 mm는 만 4년생 이상으로 추정되었다. 성비는 본 조사기간에 암컷은 426개체, 수컷은 394개체가 채집되어 1 : 0.95이었다. 흑천에 도입된 묵납자루는 St. 5~St. 6에 서식하고 있었고, 개체군 크기는 작았다. 끝으로 흑천에 서식하는 어류의 보전방안에 대해 논의하였다.
