Abstract: To promote the healthy development of aquaculture, by hardware architecture and software design, we developed a digital management system for pond culture based on.NET framework technology and Access database. The hardware architecture consists of water quality monitoring and management system, automatic feeding system and feeding decision system. According to the information such as water temperature, dissolved oxygen, pH and fish growth, we determined the reasonable feeding amount and the best feeding time, which realized the digital management for pond culture. The experiment shows that the system can monitor and control water quality in real-time to realize accurate feeding; it reduces feed conversion ratio by 20% averagely, and increases feeding amount by 1.5~2.0 times.
