강원도 홍천군 서면 반곡리에서 1999년 3월부터 2000년 2월까지 Gobiobotia brevibarva를 대상으로 산란생태를 조사 연구하였다. 본 종의 서식지는 유속이 빠르며 하상이 작은돌, 자갈로 이루어진 여울역이었다. 산란장은 수심 20~50 cm, 유속 0.6~1.3 m/sec 그리고 하상구조는 cobble과 boulder로 이루어진 곳이었다. 암 수 성비는 1 : 0.86이었으며 산란성기는 수온이 $18{sim}20^{circ}C$가 되는 5월이었으며 생식활동의 시작은 암컷 체장 50 mm, 수컷 체장 40 mm 이상이 되어야만 성적으로 성숙하였다. 평균포란수는 평균 $2,040{pm}400.57$개, 난의 직경은 $1.98{pm}0.06;mm$였다. 성숙란은 밝은 노란색을 띤 완전한 구형으로 침성란이었다.
The reproductive ecology of Gobiobotia brevibarba was investigated at Hongchen River of Bangokri, Seomyon, Hongcheongun, Kangwondo, from March 1999 to February 2000. The favorite habitat was a stretch of river with fast flow and a stream bed mostly covered with cobbles and pebbles. The spawning ground was a riffle area 20~50 cm deep, with a current velocity of 0.6~1.3 m/sec, and a bottom consisting of cobble and boulder. The sex ratio of female to male was 1 : 0.86. Peak spawning season was May when water temperatures rose to $18{sim}20^{circ}C$. Male and females became sexually mature when they attained more than 40 mm and 50 mm in body length, respectively. The average number of eggs in the ovary was $2,040{pm}400.57$ and the egg diameter was $1.98{pm}0.06;mm$. The matured eggs were demersal, spherical, and dimmed light yellow in color.
