ARTIFICIAL FISH REEF USING METAL NET BAG CONTAINING STONE

摘要

PURPOSE: An artificial fish reef using a metal net bag containing stone is provided to minimize the danger of breakage and burying during construction, and to prevent it from moving caused by an ocean current. CONSTITUTION: An artificial fish reef(10) is fabricated by using a metal net(11) having rectangular parallelepiped appearance. Stones of specific size is filled in the metal net bag to a desired height. A porous three-directional pipe(13) is installed on the top side of the stones. The stones serves to facilitate the sinking of the artificial fish reef when it is thrown toward the bottom of the sea, and serves to prevent it from moving caused by an ocean current. The porous three-directional pipe devises the smooth flow of the ocean current by preventing the ocean current from being congested. Therefore, the aggravation of the water quality is prevented. Also, the stones is constituted by using waste stones and the porous three-directional pipe is fabricated by using wastes, thereby the reuse of waste-materials is facilitated.
