Abstract: The present invention generally relates to a smart nanosensor-based system for the early and predictive monitoring of dissolved oxygen depletion in aquaculture water bodies. The system includes a submersible sensor probe with a nanostructured sensing element for quantifying the dissolved oxygen concentration, a temperature sensor, and a communication module for transmitting the measurements of the sensor to a processing unit. The sensing element is designed using nanotechnology to increase the sensitivity of the sensor and to respond quickly to changes of the dissolved oxygen concentration. The processing unit runs an artificial intelligence model set to detect temporal patterns in current and historical dissolved oxygen measurements, water temperature, and time-of-day data that indicate an impending oxygen depletion scenario. The present invention is a monitoring system that is capable of predicting a trajectory for the dissolved oxygen and estimating a time to a species- specific predetermined threshold. This is in contrast to conventional monitoring systems which have a limited capacity to provide current dissolved oxygen measurements and/or a reactive alert to a threshold of dissolved oxygen. If the depletion is predicted to occur within a fixed time period, the system issues an early warning signal and, in an automatic embodiment, switches on a corresponding aeration device via a control relay before the critical oxygen condition is reached. The system can monitor the dissolved oxygen and adjust the aeration based on continued monitoring of the sensors, which allow it to know when the dissolved oxygen has stabilized within a safe range. A closed-loop system of nanomaterial-enhanced sensing, predictive artificial intelligence, species-specific threshold configuration and automatic preventive aeration is achieved to prevent sudden oxygen collapse, limit mortality of aquatic organisms and enhance aquaculture management.
