To provide aquaculture equipment improving taste and safety.SOLUTION: Aquaculture equipment 100 includes: a water tank 101 storing seawater W and accommodating shellfish or fish subject to aquaculture; water intake means 112 for introducing underground seawater into the water tank 101; and drainage means 103 for draining the seawater W in the water tank 101; and changes the seawater W in the water tank 101 by causing the drainage means 113 to drain the seawater W in the water tank 101, while causing the water intake means 112 to introduce the underground seawater. The aquaculture equipment further includes a bubble generator 7 that generates microbubbles with the grain size of not less than 10 μm and not more than 100 μm to supply the inside of the water tank 101 therewith, and generates nano-bubbles with the grain size of less than 10 μm to supply the inside of the water tank 101 therewith.SELECTED DRAWING: Figure 1 【課題】味と安全性の向上を図った養殖装置を提供する。【解決手段】海水Ｗを貯留し養殖対象となる貝類または魚類を収容する水槽１０１と、水槽１０１内に地下海水を導入する取水手段１１２と、水槽１０１内の海水Ｗを排水する排水手段１０３と、を備え、取水手段１１２で地下海水を導入しつつ、排水手段１１３で水槽１０１内の海水Ｗを排水することで、水槽１０１内の海水Ｗの入れ替えを行う養殖装置１００であって、粒径１０μｍ以上１００μｍ以下のマイクロバブルを生成し水槽１０１内に供給すると共に、粒径１０μｍ未満のナノバブルを生成し水槽１０１内に供給するバブル発生装置７を備えた。【選択図】図１
