Experimental 100 sweet fishes (Plecoglossus altivelis altivelis) were extinct during one hour of flushing dam sediments. To establish the cause of the death of the sweet fishes, the samples were collected from Kurobe River in order to examine their gills and stomach, which showed tissue damage and choke-up with clay particles, derived from the fl ushed dam sediments. For comparison between dam sediments and choke-up with clay particles, were analyzed using X-ray powder diffraction and scanning electron microscopy equipped with energy dispersive analyzer. Abundant smectite, chlorite, mica clay minerals and kaolin minerals were found in the gill and stomach of the death body of sweet fishes, suggesting effects of the sediments on downstream ecosystems.}, pages = {40--45}, title = {ダム排砂時のアユのエラに認められた粘土鉱物}, volume = {46}, year = {2007} }
