PROBLEM TO BE SOLVED: To prevent preying on each other, to reduce stress and to prevent the damage or the like of each individual by securing a wide migrating space at the transportation of fries or the like of tuna, and to promote the growth under transportation. SOLUTION: A continuous, endless and sealed running water passage 20 is formed so as to wind almost each surrounding of a plurality of core pillar bodies 10 stood as supporting members while alternately changing the right and left turning directions, and a water current passing in one direction in the water passage 20 is formed. The live fish F is transported while being grown in the water current. The water passage 20 is constituted by setting difference in levels at least at a height interval of the surrounding part 22 in the upper and lower direction between the arc-shaped surrounding part 22 following the outer periphery of each of the parallelly arranged core pillar bodies 10, and the terminal part position of the surrounding part 22, and obliquely connecting the terminal part of one surrounding part 22 with the terminal part of the other surrounding part 22 in the upper and lower direction to integrally continue the surrounding connecting parts 23 in a mutually crossed state in the plane view between the mutual core pillar bodies 10.
