METHOD FOR ARTIFICIALLY PROLIFERATING CORAL REEF AND BED FOR ARTIFICIAL PROLIFERATION

摘要

PPROBLEM TO BE SOLVED: To attain artificial proliferation of a coral reef and perform proliferation and renaturation of the coral reef and perform creation of a seaweed bed and raising of fishing ground without having bad influence on environment. PSOLUTION: Embedding holes are provided in each block of shirasu welded tuff and small pieces of coral reef are fixed into the embedding holes and the block is arranged on the sea bottom and fixed. Since the diameter in the hole bottom of each embedding hole is made larger than the diameter of hole opening of the each embedding hole, small pieces of coral reel fixed to the holes are stabilized. Color tone of coral reel can be beautified by adding coal to the bottom of the each embedding hole. PCOPYRIGHT: (C)2006,JPO&NCIPI
