Smart IoT-based Feeder System for Koi Fish (Cyprinus rubrofuscus) Aquaculture

Aquaculture is a method of cultivating marine life from coastal waters for the purpose of producing food, commercial products, and restoration of the water ecosystem. The adoption of technologies provided innovative approaches, particularly in the realm of Industry 4.0 in enhancing the efficiency and sustain ability of aquaculture practices. This research focuses on incorporating an IoT -based feeder system for koi fish (Cyprinus rubrofuscus) which aims to monitor the environment and control the quantity of food given to the school of fish. This system comprises IoT sensors, actuators, and micro controller units linked to the internet for surveillance of waterlife quality optimal for the growth and cultivation of the fish. The main components of the system are ESP32 micro controller, water quality sensors and servo motors. The integrated software is programmed for a timely feeding cycle and instant data processing. The installed systems, such as ThingSpeak, allow remote monitoring and control providing the agriculturist analytical data and instruments for the visualization of the tank control and feeding schedules. As such, the application of the IoT technology in aquaculture leads to a progression in cultivating fish farming through a customizable intelligent feeder system. Moreover, incorporating an intelligent feeder system increases the efficiency in productivity for fish farming achieving a more sophisticated and sustainable aquaculture management practice.
