PROBLEM TO BE SOLVED: To develop an apparatus for transporting live fishes by a simple, small-sized container while keeping their lives. SOLUTION: Water in a cooler box thermally insulated by a heat insulating material is kept at a low temperature by cooled air and simultaneously oxygen is supplied to water. Further a heat conduction plate to be cooled by a Peltier element is immersed in water in the container and the temperature is dropped to make the live fishes in a torpid state in water. Consequently, the consumption of oxygen is extremely controlled, the existence of the live fishes are maintained and their freshness is retained. When the live fishes are returned to normal- temperature water, the live fishes recover activity in an original state.
