초록

2015년 5~6월에 전라북도 남원시 식정동 섬진강 수계 요천에서 한국고유종 섬진자가사리 Liobagrus somjinensis의 자연산란장 11개 지점에 대한 특징을 조사하였다. 자연산란장은 하상기질에 따라 256 mm 이상의 큰돌 (boulder)이 놓여진 상부와 자갈 (pebble)과 모래 (sand)로 이루어진 하부로 구분되었다. 큰돌 아래의 자연산란장은 작은 구멍 안에 난괴 (egg mass)를 형성한 알 덩어리와 섬진자가사리 1개체 (수컷)가 위치하였고 어떠한 저서성 무척추동물이나 유기물이 없는 깨끗한 상태였다. 알은 구형의 노란색으로 투명한 막으로 둘러싸여 있었고 알 크기는 $3.31{\pm}0.15mm$ (n=30)로 나타났다. 큰돌 아래 자연산란장에서 확인된 각 알 덩어리는 유사한 발생단계였고 각각은 상실기에서 안구 형성기까지 나타났다. 11개의 자연산란장에서 확인된 알수는 평균 $121{\pm}35.5$ (84~176)개였고 암컷의 난소에서 확인된 포란수는 $143{\pm}31.3$ (110~232)개였다.

The characteristics of 11 spawning sites in the natural environment of the Korean endemic species, Liobagrus somjinensis were investigated in the Yocheon (stream) of Seomjingang (river), located in Sikjeong-dong, Namwon-si, Jeollabuk-do, Korea from May to June 2015. The spawning sites had largely two parts, the upper region close to the surface of the waters and under region at bottom: the upper part was covered with a large and flat boulder over about 256 mm in size, whereas the under part consisted mainly of pebbles and sand. The large boulder put on the upper region may be seen as a bulwark for guarding eggs laid at the under (bottom) region. All the sites under the boulder showed a similar structure having a small hollow filled with an egg mass and an individual (male). The spawning bottoms left clean having no any benthic invertebrates and detritus. The egg shape was spherical, yellow and covered with a transparent membrane and the egg size was $3.31{\pm}0.15mm$ (n=30) in diameter. The development stage of each egg mass under the boulder was almost same from morula stage to formation stage of eye lens. The average number of eggs in 11 spawning sites was $121{\pm}35.5$ (84~176) and the average number of female fecundity in ovary was $143{\pm}31.3$ (110~232).
