To examine the function of artificial reefs for gathering fishes, fish faunas were observed by using SCUBA on artificial reefs in sandy and rocky bottom areas and on natural reefs around Hatsu Shima Island, and compared among the reefs. There was a slight difference in the fish faunas between the two artificial reefs, but totally these faunas were same as those on the natural reefs. Fishes gathering around the artificial reefs were classified into three types according to the activities in the daytime: 1) settled, 2) active and 3) floating-types. For settled and active-type fishes, the artificial reefs functioned the same as natural reefs. For floating-type fishes which act in the nighttime, the artificial reefs functioned as a rest place in the daytime. The artificial reef which was located in sandy bootom area and isolated from natural reefs was seemed to have strong gathering effect for floating-type fishes.
