2. Description of the Related Art Due to unusual marine conditions in the waters near Japan, and damage by fish, sea urchins, turban shells, abalones, and other algae-eating organisms, the shore where swordfish, kelp, alame, etc. had been breeding up to now disappears, and lime thereafter. Algae etc. make it calcareous and cause "iso-yake".

Various methods and apparatuses for growing seaweeds and seaweeds in the sea have been proposed as a method for recovering from this sea-burn.
The inventor of the present invention has proposed a seaweed bed creation mat for growing seaweeds and creating a seaweed bed in Japanese Patent Application Laid-Open No. 9-140284. In Japanese Patent Application Laid-Open No. Hei 10-237843, a net-like three-dimensional structure to which artificial seagrass is attached is installed on a river or a coast,
It aims to prevent erosion of riversides and beaches and to inhabit shellfish and algae. Also, Japanese Patent Application Laid-Open No. 11-89477 proposes a method for laying artificial seaweed to be laid on the seabed.

[0004] These known techniques are effective in protecting the seashore and growing natural seaweeds and seaweeds. There are drawbacks that it takes a long time to attach and that the attached natural spores are limited to spores of seaweed and seaweed in the vicinity. Further, the present inventor has disclosed in Japanese Patent Application No. 11-231581.
In order to remove red tide algae that cause red tide, the article proposes to attach spores of Donariella, a kind of seaweed, to artificial seagrass. However, both this known technique and the above-mentioned known technique have a drawback that attached spores and germinated sprouts are washed away by the sea current because they are made of thin ribbon-shaped leaf-like artificial seaweed.
