20140251225 | COMPLEX FLOATING WETLAND EQUIPMENT - An otter habitation section, an overland section, an inclined-surface section, a first spawning section, a second spawning section and a roost are all provided. Accordingly, otters and birds can sufficiently obtain preys, and fishes secure a spawning ground suitable for spawning characteristics. Therefore, the otters, the fishes and the birds can inhabit together. Further, since frames are made of wood for providing buoyant force or the frames are made of stainless steel for reinforcing strength and wood for providing buoyant force, a small amount of polyethylene foam is required. Accordingly, it is possible to obtain floating wetland equipment with a simple structure. Furthermore, the wooden frames itself provide a spawning ground of fishes. | 09-11-2014 |
