An average value of a plurality of environmental pH values measured at the depth position of a breeding pond, an average value of a plurality of environmental temperature values, an average value of a plurality of environmental dissolved oxygen values, and a plurality of environmental salinity values An average value. For example, the aquaculture environment monitoring method described in item 1 of the scope of patent application, wherein in step (S60), t _pH , t _t , t _OD and t _s in the relational expression of the control judgment rule are respectively in the target aquaculture pond An environmental pH value to be monitored, an environmental temperature value to be monitored, an environmental oxygen capacity value to be monitored, and an environmental salinity value to be monitored are measured at the depth position. According to the aquaculture environment monitoring method described in the first item of the scope of patent application, in step (S70), each of the plurality of actuators includes a motor waterwheel and a pump. According to the aquaculture environment monitoring method described in the first item of the scope of patent application, the at least one water quality platform monitoring system and the embedded central processing system both have a shell, and the shell is made of a heat-resistant and corrosion-resistant plastic material. According to the aquaculture environment monitoring method described in item 1 of the scope of patent application, an outer surface of each of the plurality of sensors is covered with a filter. According to the method for monitoring an aquaculture environment according to item 6 of the scope of patent application, the at least one water quality platform monitoring system is arranged on an axis of at least one of the motor waterwheels. According to the aquaculture environment monitoring method described in item 1 of the scope of patent application, at least 5 sets of the water quality platform monitoring system and at least 5 sets of the actuators are installed in each subdivision of the target aquaculture pond.
