PROBLEM TO BE SOLVED: To provide an overland culturing apparatus capable of corresponding to danger-free culturing technique capable of corresponding to red tide, infectious diseases and change in water temperature and further corresponding to water purification and not polluting ocean by using sound-free and vibration-free simple facilities without using conventional pumps containing blowers and compressors and without requiring soundproof, vibration-proofing and cooling facilities. SOLUTION: This overland culturing apparatus feeds fresh water or sea water in which dissolved oxygen concentration is automatically increased to a rearing tank and a septic tank by using a pump for a gas-liquid mixed stream and sets rearing environment which is preferable to fishes and shellfishes by utilizing characteristics of the sound-free and vibration-free pump having low speed rotation and rears fishes and shellfishes and continuously carries out purification of organic materials, discharge of formed sludge of phosphorus and nitrification of ammonia and denitrogenation by effectively realizing aerobic properties and anaerobic properties, and as necessary, carries out the control of water temperature, pH and sterilization and drug administration and maintains rearing environment which is friendly to fishes and shellfishes.
