The method to pump up ayu fish (Plecoglossus altivelis T & S) from beneath dam to upper stream of a river was tested. Also, the reactions of the fish to various acoustic noises and to several colored boards were observed. The results obtained are summarized as follows: 1) It was found that ayu fish can be pumped up by fish pump from beneath dam to upper stream of a river (Figs. 1, 2, and table 1). 2) The fish was stimulated by the under water noises of low frequency, and it is suggested that the pumping efficiency could be increased by using these acoustic noises (Tables 2, 3, and Fig. 4).
