PROBLEM TO BE SOLVED: To provide a method for extremely advantageously culturing migratory fishes, capable of spawning parent fishes in a vessel in natural state and efficiently obtaining many health juveniles by charging adult fishes into water in the vessel and changing many conditions of water in the vessel so as to make these conditions gradually coincide with specific conditions. SOLUTION: Adult fishes are charged into water in a vessel and conditions of temperature, pressure and further, water quality, etc., in the vessel are changed so as to make these conditions gradually coincide with the conditions of a spawning ground. This culturing apparatus 1 for aquatic life has a pressure tank 60 for charging aquatic lives and water therein, a relay tank 20 for storing water feeding to the pressure tank 60 once under atmospheric pressure and controlling the pressure, a water feeding means 30 for feeding water in the relay tank 20 into the pressure tank 60, a water temperature controlling means and a water control means in the pressure tank 60.
