| Research Abstract |
A research was conducted to clarify spawning and nursery grounds of the fishes living in the river of mountainous area, the Ou River located near LOUANG PHRABANG, Northern Laos. Species and individual numbers collected in dry seasons were much higher than those of rainy season. Fishes in dry season used river itself as spawning and nursery grounds. These results will reverse the common sense that freshwater fishes of tropical area spawn and grow in a flood plain in rainy season.
