PROBLEM TO BE SOLVED: To provide a device of culturing fish and shellfish which can be installed in any place, can culture the fish and shellfish densely in a small quantity of water and gives an excellent yield of adult fish, and to provide a method of culturing the same.SOLUTION: In a device having, in a plurality of fish tanks 2, 2 and 22, a circulation water supply passage 5 from respective pump, a circulation return water passage 6 mounted between a fish tank and the pump, and a screen filter device 7 mounted in the circulation return water passage 6 for filtering discharged water continuously, recovering fish excrement and residual bait and circulating culturing water in each fish tank, when an oxygen sensor 20 in each fish tank detects not more than 90% of an oxygen saturation degree, an automatic controller 21 opens a valve 3B in an oxygen water supply passage 3A of a fish tank regarding the detection to supply high concentration oxygen water to the culturing water of the tank regarding the detection, maintain the stable high concentration state of oxygen of the culturing water and culture a large amount of fish in a small quantity of water.COPYRIGHT: (C)2014,JPO&INPIT【課題】 本発明は、設置場所を選ばず、少水量でかつ高密度で魚介類の養殖をすることができ、成魚の歩留率の優れた魚介類養殖装置と方法を提供する。【解決手段】 複数の魚槽2、2、22に、それぞれポンプから循環給水路5と、魚槽からポンプの間に循環還水路6とを設け、循環還水路6に設けたスクリーンフィルタ装置7により、排水を継続的に濾過して魚糞・残餌を回収し、各魚槽内の飼育水を循環させるようにした装置において、各魚槽毎に酸素センサ20で酸素飽和度90%以下を検知したとき、自動制御装置21が検知に係わる魚槽の酸素水供給路3Aにおけるバルブ3Bを開放して、高濃度酸素水を、当該検知に係る魚槽の飼育水に供給し、飼育水の安定した酸素高濃度状態を維持させ、少ない水で多量の魚を養殖する。【選択図】 図2
