This paper is a report on research into the fish gathering around a large-scale high -rise artificial steel reef set up in May, 1999, located off Nagano, Yamaguchi prefecture in the Sea of Japan. The research was carried out from 1999 through 20 for the fiscal year. The research was performed mainly by diving and fishing. The result was that the gathering of jack mackerel and yellow tail was most remarkable in autumn; and shows that this artificial reef is more effective in gathering these fishes than the other existing artificial reefs. Also, the research shows that predators such as amberjack and true bass gathered in the artificial reef as the quantity of small fish food source increased.
