CULTURE EQUIPMENT FOR FISHES AND SHELLFISHES

PROBLEM TO BE SOLVED: To provide a rearing equipment for fishes and shellfishes, with which rearing is advantageously carried out in terms of profit, and pathogenic bacteria in natural water can be prevented from entering a rearing water tank by switching operations between a closed circulation system and an over-flow system. SOLUTION: The rearing equipment for fishes and shellfishes is equipped with the rearing water tank 1 for rearing fish and shellfish, a solid substance removal tank 2 for removing solid substances in water, an ammonia removal tank 3 for removing ammonia in water, a sterilization tank 4 for sterilizing water, a temperature regulator 5 for regulating a water temperature, an oxygen supply apparatus 6 for supplying oxygen to water and a circulation pump 7. The rearing equipment for fishes and shellfishes is equipped with two routes exchangeable between a closed circulation route 8 for circulating water in the rearing water tank 1 through the solid substance removal tank 2, the ammonia removal tank 3, the sterilization tank 4, the temperature regulator 5 and the oxygen supply apparatus 6 by the action of the circulation pump 7, and an over-flow route 9 for supplying natural water through the sterilization tank 4 to the rearing water tank 1 and discharging water in the rearing water tank 1.
