Abstract
The distribution patterns of Oryzias latipes, was revealed in Marugame, Kagawa in 2001-2003 and 2011. Between the surveys, O. latipes did not decrease significantly, though a land conversion of rice field into the residential zone had progressed. The presence probability of O. latipes was predicted using the land use, river system, the distance from the nearest pond, elevation and slope. As the result, the area of the mainstream and ponds within 100 m of a sampling site negatively affected the presence probability of O. latipes. The area of rice field and residential zone within 100 m of a sampling site positively affected the presence probability. The results indicated the possibility that the boundary zone between the rice field had become suitable as a habitat for O. latipes.
