Re-connecting the ecological network in the ditches of modernization of paddy field for the oriental weatherloach (Misgurnus anguillicaudatus) on Sado island

对佐渡岛国中地区52个现代化沟渠的东方雨泥鳅（Misgurnus anguillicaudatus）分布及其相关环境因子进行了调查。GIS、GLM和AIC分析表明，不同季节泥鳅密度的有利因素不同。我们还制作了一张GIS地图，预测了国中地区所有沟渠的泥鳅密度。我们讨论了如何将潜在分布图应用于东方风沙的管理。

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.
