초록

남한강 지류 흑천에 재도입(2010~2012년)된 묵납자루의 서식현황을 밝히기 위해 2017년부터 2018년까지 서식현황을 조사하였다. 조사결과 2017년(2회 조사)에는 329개체를, 2018년(4회 조사)에는 723개체를 채집하었고, 서식범위는 방류지점을 포함하여 약 5 km 구간이었다. 묵납자루의 집단서식지는 방류지역소의 상류부로 유속이 있고 수심 0.4~1.2 m이며 큰돌과 돌이 많은 곳이었다. 산란기는 산란행동 및 당년생 치어 크기로 볼 때 4월부터 6월로 추정되었으며, 성비는 암컷 438개체, 수컷 412개가 채집되어 1 : 0.94였다. 연령은 4월을 기준으로 전장 32~43 mm는 만 1년생, 50~61mm는 만 2년생, 62~75mm는 만 3년생, 76~89 mm는 만 4년생 이상으로 추정되었다. 연령별 구성비는 채집시기에 따라 차이를 보였지만 1년생(또는 당년생), 2년생, 3년생, 4년생 이상의 순으로 높게 나타나 안정적인 연령구조를 보였다. 따라서 흑천에 복원을 위해 재도입된 묵납자루는 성공적으로 정착하여 안정적인 개체군을 이루고 점점 확산되는 경향을 보였다.

This study was conducted from 2017 to 2018 to determine habitat aspects of Acheilognathus signifier, an endangered species reintroduced (2010~2012) to Heukcheon Stream, a tributary of the Hangang River, Korea. A total of 329 individuals were collected in 2017 (two surveys) and 723 individuals were collected in 2018 (four surveys) at about 5 km habitat area, including the discharge station. A. signifier's habitat was about 0.4 to 1.2 meters deep in slow water flow upstream of the discharge area. It was a place with many boulders and cobbles. The spawning period was estimated from April to June in terms of spawning behavior and collected juvenile size. Sex ratio of females (438) and males (412) was 1 : 0.94. Estimated age of A. signifier based on their total length distribution during the spawning period (April) indicated that 1-, 2-, 3-year old groups and more than 4-year-old group were 32~43 mm, 50~61 mm, 62~75 mm, and 76~89 mm, respectively. Age-specific composition costs differed depending on the timing of the collection. They were relatively high in the order of first-year (juvenile)>third-year> and fourth-year or higher, showing a stable age structure. Thus, A. signifier reintroduced to Heukcheon Stream has successfully settled down and formed a stable population, showing a tendency to proliferate.
