초록

멸종위기에 처한 우리나라 고유 담수어류인 얼룩새코미꾸리 Koreocobitis naktongensis의 호르몬 처리에 의한 산란행동을 관찰하기 위하여 2010년 4월 20~27일까지 산란시기에 성 성숙 호르몬(Ovaprim)을 주사하여 산란행동을 관찰하였다. 산란행동을 분석한 결과 산란 전 행동, 산란행동, 산란 후 행동으로 구분되었다. 산란 전에는 주로 휴식과 유영을 반복하였다. 호르몬 주사 후 평균적으로 11~12시간 경과하면 산란행동을 시작하여 암·수 1 : 1로 1~18회 산란하였고, 수중에서 수컷이 골질반을 이용하여 암컷의 등지느러미 뒷부분의 몸을 원의 형태로 감싸안고 산란이 이루어졌다. 산란 후 행동에서는 특별한 난 보호행동은 보이지 않았으며 산란에 참여하지 않은 개체들이 수정란 일부를 섭식하는 것이 관찰되었다.

The Nakdong nose loach, Koreocobitis naktongensis is an endangered freshwater fish endemic to Korea. The spawning behaviour of the K. naktongensis was observed after treating Ovaprim in laboratory aquarium from 20~27 April 2010. The behavioral patterns were categorized into three stages of pre-spawning, spawning and post-spawning behaviors. Before spawning K. naktongensis usually repeated taking a rest and swimming. On average, initial spawning activity started 11 to 12 hours later after injection with Ovaprim. During the spawning period, the number of spawning acts ranged from 1 to 18. The spawning ratio of female to male was 1 : 1. The male embraced the back of the female's dorsal fin with his lamina circularis. It looked like a complete circle at that time. After spawning, parental care was not observed. Individuals not participating in spawning have been observed to feed on some of the fertilized eggs.
