| Research Abstract |
The distribution of the oriental weatherloach, Misgurnus anguillicaudatus, together with related environmental factors were surveyed at 52 ditches of modernization in the Kuninaka region on Sado island. Analysis with GIS, GLM and AIC revealed that positive factors for the loach density were differed from each season. We also produced a GIS map that the predicted the density of loach across all ditches within the Kuninaka region. We discuss how the potential distribution map can be applied to the management of the oriental weathetloach.
