The catches of fishes in number by gill nets in the Sarutani Reservoir which was filled in 1956,were in vestigated in August, 1963. The contents of the catch at Sakamoto as well as at Sakamoto-ichiba in 1963 were similar to that in 1962 (Figs. 1 and 2). This result confirms the estimation stated in the previous paper that the composition in number of fish fauna in the reservoir changed to that of the stagnant water type from that of the running water type which is seen in the tributary at present. Considerings that the yearlings are not able to be catched by gill nets in August, the above mentioned change took place from 1960 to 1962.
