Abstract

This study investigated the fish fauna of Jeonjucheon and Samcheon Streams, flowing through the city of Jeonju, through surveys conducted at 10 sampling sites using kick net and cast net. The fish fauna collected included 10 families and 36 species, with a total of 2,064 individuals. Samcheon had 8 families and 30 species with 1,074 individuals, Jeonjucheon had 8 families and 26 species with 986 individuals. The dominant species was Zacco platypus with 1,202 individuals, and a total of 153 individuals of the subdominant were Pseudogobio esocinus. In Jeonjucheon Stream, a total of 567 individuals of the dominant species were collected as Z. platypus and 99 individuals of the subdominant species were collected as Pungtungia herzi, and there was no significant change in the stream environment except for the confluence site. Further expanded research covering the entire Jeonjucheon and Samcheon Streams region, accompanied by regular monitoring, is essential to record and understand fluctuations in fish fauna.

전주 시내를 관통하여 흐르는 전주천과 삼천의 어류상을 연구하기 위해 총 10개 정점을 선정한 뒤 족대와 투망을 이용하여 조사하였다. 출현한 어류는 4목 10과 36종 2,064개체이다. 삼천에서 4목 8과 30종 1,074개체, 전주천에서 3목 8과 26종 986개체가 채집되었다. 전체 우점종은 피라미로 총 1,202개체(58.35%)가 채집되었고, 아우점종은 모래무지로 총 153개체(7.43%)가 채집되었다. 삼천의 우점종은 피라미로 총 635개체(59.12%) 채집되었고, 아우점종은 모래무지로 140개체(13.04%) 채집되었다. 전주천의 우점종은 피라미로 총 567개체(57.51%) 채집되었고 아우점종은 돌고기로 총 99개체(10.00%) 채집되었으며, 합수부를 제외하면 하천의 환경에 큰 변화가 없었다. 복원사업 전 삼천의 전주 시내 구간 어류상은 느린 유속과 모래가 깔린 하상으로 이를 선호하는 어류가 채집되었으나, 복원사업 후 여울이 발달하는 등 환경변화로 인해 어류상의 차이가 있는 것으로 생각되며, 전주천은 복원사업 이전과 비교했을 때 종 수가 크게 증가한 것으로 파악된다. 따라서 도심하천인 전주천과 삼천의 어류군집에 대해서는 좀 더 장기적인 모니터링이 필수적인 것으로 판단된다.
