高層魚礁の開発と実用化 Development of Large-scale High-rise Artificial Reef and Its Practical Application
This paper describes an experimental large-scale, high-rise artificial reef designed by the authors with theintention of developing an offshore fishing ground in deeper waters and a large-scale, high-rise reef for practicaluse based on application of the results obtained from the experiments. The experimental reef, the world's largestartificial reef with a height of 35m and 4,000m<sup>3</sup> in volume, is located 20km off Nezugaseki, Yamagata Prefecture,in the northem part of the Sea of Japan, in the neighborhood of a natural reef (Ohse Reef) known as an excellentfishing ground for red sea bream (Pagrus major). Observation by diving and trial fishing have shown that a largenumber of fish of various species gathered and stayed around this artificial reef. The reef is now being used inpractical operation, and similar artificial reefs are being built in many other fishing grounds.
