As is true for any organism, the population of Oncorhynchus masou is influenced by the habitat. This study investigated the relationship between the population of young cherry salmon and the river environment, toward gaining knowledge necessary for conservation, improvement, and restoration of the river environment. Based on a survey of the Meppu River in the Shiribeshi Toshibetsu River system, we assessed variables in the physical environment, including flow velocity, water depth, Froude number, area of pools and riffles, amount of food supplied from upstream, position and elements expressing a location’s suitability as a resting place for Oncorhynchus masou, and we clarified the optimal environmental conditions for Oncorhynchus masou.}, pages = {477--482}, title = {サクラマスの生息環境向上のための河川物理環境の評価}, volume = {11}, year = {2005}, yomi = {ヤベ, ヒロキ and ナカツガワ, マコト and ウラベ, ヒロカズ and ナカジマ, ミユキ} }
