PURPOSE:To enable to admit fishes separately according to their types, by holding parallel water penetrative partition plates tobe removable, in plural layers in a water tank, furnishing a water intake at the bottom of the tank and water flow outlets at the side walls of the partition plates of those layers, and connecting those outlets to exhaust pipes through switch valves. CONSTITUTION:Parallel water penetrable partition plates, 2 formed of a frame 14 stretched wtih a wire net 13, are held removable by supporters 15 in plural layers inside a water tank 1. At the bottom of the water tank is furnished a water intake 8 connected to a seawater suction pipe 10, a valve 7, and a pump 9, and, at the side wall of each partition plate 2 is furnished a water flow outlet 4, which is connected to an exhaust pipe 5 through a switch valve 6. Since the water tank nnis not required to circulate to the seawater under the ship's bottom, a loss of cruising speed is avoided, and furthermore, fished can be admitted independently according to their types, to prevent living fishes, from weakening.
