Fish Farm Monitoring System

Technology Overview

This technology aims to monitor the water quality in real-time to ensure that fishes are farmed in optimal conditions at all time. A prototype system was built to demonstrate the features of control and monitoring capabilities needed for a fish farm. Water quality issue is a challenge for aquaculture as water has direct impact on the health of the fishes. Hence, water quality parameters must be monitored and controlled to ensure that the aquaculture system is optimum. The technology contributes to better fisheries management and environmentally sustainable aquaculture by using the latest control technologies.

The technology proposes the control and data communication architecture to achieve the required monitoring specifications. The main control system includes Programmable Logic Controller (PLC), Human Machine Interface (HMI) and IoT gateway. A prototype system was implemented with the latest process sensors and transmitters needed in a fish farm. Additionally, the system also implemented an auto-alert function with Email and SMS notifications to a user. The alerts generated allow the user to have an instantaneous action required for the water parameters from the control tolerances. The system is also attached with a web camera to enhance the monitoring solution with visualization capability.
