ARTIFICIAL SEAWEED BED MATERIAL

PROBLEM TO BE SOLVED: To provide an artificial seaweed bed material using an inexpensive material, maintaining flexibility over a long period, raising an affinity for organisms and saving labor and time for the final treatment required during disposal. SOLUTION: The artificial seaweed bed material is obtained by using a foam of a polyolefin resin as a principal material, adding carbon powder to the foamed resin and forming the resultant artificial seaweed bed material into a sheetlike state. The artificial seaweed bed material is cut to a suitable size to form each sea tanglelike floating body 4. The resultant floating body 4 is connected to a weight 2 and a base 1 is installed in the water bottom of the sea, lakes or marshes or rivers. The floating body 4 drifts waveringly in water by buoyancy of its own to provide a habitat suitable for the organisms. Furthermore, a foam of a biodegradable resin is used as the principal material and the carbon powder is added to the foamed resin. Thereby, the artificial seaweed bed material is formed into the sheetlike state. COPYRIGHT: (C)2003,JPO
