Abstract

In tropical to subtropical marine areas, coral bleaching frequently occurs probably due to environmental destruction and global warming, and coastal ecosystems are degrading. JFE Group is engaged in technological development for restoring coral reefs, which have been damaged due to bleaching, etc., by combining the coral-implanting tool, which was developed by Tokyo University of Marine Science and Technology to prepare the substrate for coral larvae, and the carbonic solid of iron-steel slag “MARINE BLOCK^®.” This paper reports on the healthy growth of young coral on Marine Block in the ongoing test in the actual sea.
