Marine forest structure

Abstract

The present invention is to provide a marine forest structure by which many kinds of fishes and shellfishes can gather and inhabit and to which useful seaweeds such as of Laminariaceae and the like can adhere to propagate when the structure is submerged and disposed on the bottom of the sea. Provided is a marine forest structure 1 which is composed of a base 2 in which legs 5 are protruded from a peripheral edge of a flat plate 4 in which plural holes 6 are provided in a central part and a peripheral part thereof and two kinds of pillar bodies 3 a, 3 b whose lengths are different. The marine forest structure is constructed such that a plurality of pillar bodies 3 a which has a predetermined height are raised from and fixed to the holes 6 of the flat plate 4 and that pillar bodies 3 b which has a height lower than that of the pillar bodies 3 a with the predetermined height are raised from and fixed to the plural holes 6 of the periphery of the flat plate 4.

1 . A marine forest structure characterized by being constructed in such a way that a plurality of holes are provided in parallel in a central part of a base, that a plurality of holes are provided with a predetermined space in a peripheral part of said base, that pillar bodies with a predetermined height are raised from and fixed to the plural holes of the central part of said base, and that pillar bodies whose height is lower than that of the pillar bodies of said central part are raised from and fixed to the holes of the peripheral part of said base.  
   
   
       2 . The marine forest structure according to  claim 1 , characterized by being constructed in such a way that a plurality of legs are allowed to protrude from an outer peripheral edge of a flat plate arranged in the central part of said base.  
   
   
       3 . The marine forest structure according to  claim 1 , characterized by being constructed in such a way that the pillar bodies raised from the central part of said base and the pillar bodies raised from the peripheral part of the base are respectively mutually coupled through a frame which is coupled with the base or that the respective pillar bodies are accommodated in a frame body which is fixed to the base.  
   
   
       4 . The marine forest structure according to  claim 1 , characterized by being constructed in such a way that said pillar bodies are constituted by variety of materials such as scrap wood of telegraph poles, thinning wood of mountains and forests, or the like.  
   
   
       5 . A marine forest structure characterized by being constructed in such a way that pillar bodies with a predetermined height are raised from and fixed to a central part of a base, and that pillar bodies whose height is lower than that of the pillar bodies of said central part are raised from and fixed to a peripheral part of said base.  
   
   
       6 . The marine forest structure according to  claim 5 , characterized by being constructed in such a way that a plurality of legs are allowed to protrude from an outer peripheral edge of a flat plate arranged in the central part of said base.  
   
   
       7 . The marine forest structure according to  claim 5 , characterized by being constructed in such a way that the pillar bodies raised from the central part of said base and the pillar bodies raised from the peripheral part of the base are respectively mutually coupled through a frame which is coupled with the base or that the respective pillar bodies are accommodated in a frame body which is fixed to the base.  
   
   
       8 . The marine forest structure according to  claim 2 , characterized by being constructed in such a way that the pillar bodies raised from the central part of said base and the pillar bodies raised from the peripheral part of the base are respectively mutually coupled through a frame which is coupled with the base or that the respective pillar bodies are accommodated in a frame body which is fixed to the base.  
   
   
       9 . The marine forest structure according to  claim 2 , characterized by being constructed in such a way that said pillar bodies are constituted by variety of materials such as scrap wood of telegraph poles, thinning wood of mountains and forests, or the like.  
   
   
       10 . The marine forest structure according to  claim 3 , characterized by being constructed in such a way that said pillar bodies are constituted by variety of materials such as scrap wood of telegraph poles, thinning wood of mountains and forests, or the like.  
   
   
       11 . The marine forest structure according to  claim 6 , characterized by being constructed in such a way that the pillar bodies raised from the central part of said base and the pillar bodies raised from the peripheral part of the base are respectively mutually coupled through a frame which is coupled with the base or that the respective pillar bodies are accommodated in a frame body which is fixed to the base.
