Abstract This paper is about the development of a mobile app for integrated control and real-time monitoring of smart fish farms based on the Internet of Things (IoT). The important role of this project is to control water processing in a recirculating, smart fish farm. The proposed smart fish farm consists of two water tanks, a balancing tank, and a recirculating aquaculture system (RAS). In this aquaculture, the water flow process is regulated by the proportional integral derivative (PID) controller along with water-level ultrasonic sensors, water temperature sensors, and dissolved oxygen (DO) and potential hydrogen (pH) sensors. Remote control and the real-time monitoring are performed by using the Message Queue Telemetry Transport (MQTT) protocol, with the measured big data stored in lab servers. This designed aquaculture system operates in manual mode, automatic mode, and in remote mode by using a mobile device. To verify the performance of the designed system, field tests were conducted in the Future Creative Technology Research Institute of the Busan University of Foreign Studies and at Jangsucheon Ltd. of Gangwhado Island. Based on the experimental results, it satisfies the required performance of a smart fish farm.
