SEAWEED BED DEVELOPMENT BY USING PLASTIC ARTIFICIAL TURF TYPE ALGAL REEF BOARD

摘要

PPROBLEM TO BE SOLVED: To provide a technology for improving environmental conditions such as sea sand, mud, nutritious salts, environmental hormones, agrochemical, detergents, or the like, and difficulties for seedling production, or the like, in the artificial development of a seaweed bed for eelgrass, or the like. PSOLUTION: The subject plastic artificial turf type algal reef board is applied and fixed on an artificial concrete fishing reef already installed in the sea but exhibiting not sufficient algal bed-developing effect so as to develop the seaweed bed by a small budget. Also, without using any concrete at all, and when using the plastic artificial turf type algal bed boards from the beginning, since it is possible to fix them at the sea bottom or by leaving them from the sea bottom with a small fishing boat, a cost for developing the seaweed bed becomes extremely inexpensive, and suitable for a public construction. Problems such that a conventional seaweed bed construction requires a high cost by using a high priced concrete and using a boat having a platform, and since it has a high hydrogen ion concentration, the sea weeds do not attach easily, and from second year on, the reef is covered with protozoea, shellfishes, or the like, to widely reduce the growing conditions of the seaweeds, or the like, and the seaweed bed developmental effect is not satisfied, are solved.
