An aquaculture system is provided. The aquaculture system includes a cultivation pond, a water circulation unit, a water quality detector, and a water processing module. The cultivation pond for storing the water has a recirculation inlet and recirculation outlet. The water circulation unit is in fluid communication with the cultivation pond to allow the water in the cultivation pond to circulate through the water circulation unit. The water quality detector is used to detect the quality of the water to obtain water quality information. The water processing module includes an electrolytic gas generator and a control unit to improve the quality of water. The control unit receives the water quality information and adjusts the applied voltage on the electrolytic gas generator according to the water quality information to control the gas species and a ratio of the gases generated by the electrolytic gas generator.一種水產養殖系統包括養殖池、水體循環單元、水質偵測器以及水質處理模組。養殖池蓄積養殖水並具有循環入水端以及循環出水端。水體循環單元流體連通養殖池,使養殖水通過水體循環單元進行循環。水質偵測器偵測養殖水的水質,以獲得水質資料。水質處理模組包括電解式氣體產生器以及控制單元。電解式氣體產生器可產生第一氣體與第二氣體至水體循環單元,以改善水質。控制單元電性連接於電解式氣體產生器以及水質偵測器,其中控制單元接收水質資料,並根據水質資料調整電解式氣體產生器的電壓值,以控制電解式氣體產生器所產生的氣體種類與輸出氣體比例。1‧‧‧水產養殖系統10‧‧‧養殖池10a‧‧‧循環出水端10b‧‧‧循環入水端20‧‧‧水質偵測器30‧‧‧水體循環單元31‧‧‧出水管路32‧‧‧進水管路33‧‧‧泵浦34‧‧‧第一控制閥35‧‧‧第二控制閥40‧‧‧水質處理模組41‧‧‧過濾單元42‧‧‧純水供應裝置42a‧‧‧供水單元42b‧‧‧離子交換樹脂43‧‧‧電解式氣體產生器43a‧‧‧第一輸出管43b‧‧‧第二輸出管44‧‧‧控制單元440‧‧‧對照表A1‧‧‧第一氣體A2‧‧‧第二氣體50‧‧‧雲端主機60‧‧‧遠端監控裝置70‧‧‧供水端口70a‧‧‧進水閥80‧‧‧排水端口80a‧‧‧排水閥
