METHOD FOR MARINE CULTURING OF CORAL AND APPARATUS THEREFOR

PROBLEM TO BE SOLVED: To provide a method for marine culturing of coral by which young polyps are protected from competition with seaweeds, etc., deposition of floating mud and depletion of eating damage, etc., and the depletion of the young polyps metamorphosed from planular larvae can thereby be prevented as much as possible to raise the survival rate of the coral relocated to a natural sea area until the young polyps set on adhesion beds and metamorphosed from the planular larvae grow to young coral of a prescribed size having a hard tissue and to provide an apparatus therefor. SOLUTION: The method for marine culturing of the coral is carried out by composing culturing tools as follows. The one or two or more adhesion beds in which the planular larvae set are fixed to holding means. The resultant culturing tools are mounted on a buoyancy imparter floated on the sea surface of the natural sea area and held in positions at a prescribed height from the sea bottom. The young polyps set on the adhesion beds and metamorphosed from the planular larvae are cultured in the natural sea area while being protected with a polyp protecting means until the young polyps become the young coral having the hard tissue and are relocated to the sea bottom of the natural sea area. The apparatus for marine culturing of the coral is equipped with the culturing tools, the buoyancy imparter and the polyp protecting means. COPYRIGHT: (C)2005,JPO&NCIPI
