<P>PROBLEM TO BE SOLVED: To provide a square-shaped temporary constructed building type aquatic organism-culturing water tank divided as small parts, made of concrete and utilizing sun light as growing light. <P>SOLUTION: This square-shaped culturing water tank body 1 divided as the small parts is formed by using L-Shaped concrete blocks L having a prescribed dimensions in accordance with the civil engineering and construction standard. A chevron-shaped or dome-shaped temporary constructed roof having sun light permeability is formed. Far infrared light-generating coating is applied on the inside and outside of each of such building type water tanks to generate far infrared light minus ions. Culturing water temperature is maintained at a predetermined temperature by heat-insulating the inside and outside of the water tank and mounting a heating device. A part of Elton's ecological pyramid is derived by mounting a water-culturing device, a filtering device and the heating device in the tank, cultivating the inside of the culturing water tank for activating a carbon assimilation activity by hanging cultured tangles 27 and artificial tangles 26 in the tank to promote the homogenization of water quality, and the generation and growth of plankton and microorganisms, and then discharging target aquatic organisms. <P>COPYRIGHT: (C)2012,JPO&INPIT |
