영문 초록

Reproductive ecology of Odontobutis interrupta have been investigated in the Han river and the Imjin river, Korea from 2001 to 2003. The habitat was pool area of the middle or lower part of the stream. The major cohabitation fishes were Rhynchocypris oxycephalus, Zacco platypus and Rhinogobius brunneus. Spawning season was from May to June with the water temperature in 18～25℃ and the prosperous period was May (18～21.5℃). The current velocity of the spawning ground was 0～30 cm/sec and water depth was 39.8±10.262 cm (25～62 cm, N= 15). Mature male made the nest and had territory. The male leaded the female in the nest and spawning with reverse posture. After the spawning, the parental male guarded the eggs until hatch (nesting(♂) - lead(♂) - follow(♀) - spawning(♀) - ejaculation(♂) - guard(♂)).
