| Abstract;Distribution of the delicate loach, Niwaella delicata, was investigated at upper reaches of Kiso River in Nagano Prefecture on summer season from 2002 to 2003. The fish was present in 9 points of the upper reaches of the Kiso River that includes the main stream, the Sue River, the Nishino River, the Outaki River, the Ogawa River, the Akazawa River, the Adera River, and the Kakizore River. It was indicated that Niwaella delicate had been widely distributed throughout the upper reaches of the Kiso River before 1954, but recently the habitat had been fragmented in the main stream and restricted to the headwater reach of the tributary of the Outaki River.
