The fish catch of snow crab Chionoecetes opilio in the Sea of Japan peaked in 1970 at approximately 16,000 tons. Since then the catch has been in decline and efforts to recover these marine resources are performed. One such effort (a project subsidized by Fisheries Agency since 1982) involves the installation of artificial nursery reefs on the sea beds inhabited by snow crabs to serve as MPA (Marine Protected Area) to protect the crabs. Currently, these sanctuaries have been established in 29 places which cover a total area of 32,900ha. Furthermore, Fisheries Agency started the frontier project in 2007. In this project, installation of the artificial nursery reefs of 21 places which cover a total area of 8400ha are planned from 2007 to 2014, and installation of 10 places, 4000ha was completed now. In this research, we sought to clarify the effects of these artificial nursery reefs on the protection of snow crabs.project on this matter, being bio-logging science one of the most useful tools for this kind of research.
